Here’s what each one remembers, connects to, costs and does without being asked, what ChatGPT still does well, and when you need more than a chat. By **Trent**, founder of Retenna 25 October 2026 23 min read **Last checked 25 October 2026 How we checked** Facts come from each maker’s own website, help pages, pricing pages and App Store listing, and link to their source. Prices and ratings are from the US App Store and the makers’ own pages on 25 October 2026. These assistants change month to month, so check the maker’s page before you choose. Retenna is our product and isn’t out yet: where we describe it, it’s what it’s built to do, and its examples show how it works, not test results. In 30 seconds - **If your life runs on Google:** Gemini works with Gmail, Calendar and more, and briefs you each morning in the US, though its most personal features aren’t in the UK or the EEA. - **For thoughtful help with your inbox:** Claude remembers you even on its free plan, and once you connect Google it can draft emails and add events, asking before each action. - **For errands done for you:** Muse from Meta books, buys and follows up with your OK, in the US for now. Copilot suits homes on Outlook and Microsoft 365, and Perplexity gives quick answers with sources. - **ChatGPT is still a strong all-rounder**, with memory, scheduled tasks and Google connections, but ads now appear on its Free and Go plans. - **Retenna** runs its own AI, built deeper for everyday life: every lifestyle expert in one app, each with a full space, answering your everyday questions already knowing you. Not out yet; [early access is open now](https://retenna.ai/#join-final). ## The short answer There’s no single best alternative; it depends on where your life already lives. Gemini is the natural pick if you use Gmail and Google Calendar, Copilot if you use Outlook and Microsoft 365, and Claude if you want careful help with your inbox and calendar. Muse from Meta goes furthest at doing errands for you, in the US for now, and Perplexity is quickest for answers with sources. All of them are general assistants: they help when you ask. If you want your everyday questions answered by something that already knows you, and your outfits, meals, training, rest and plans looked after and planned around each other, that’s what we’re building Retenna to do, with its own AI, built deeper for everyday life. ## Why people look for a ChatGPT alternative ChatGPT is still the assistant most people start with, but a few things have changed this year: - **Ads.** OpenAI started testing [ads in ChatGPT](https://help.openai.com/en/articles/20001047-ads-in-chatgpt) in the US in February 2026, and they now run in [89 countries](https://openai.com/index/chatgpt-ads-expands-26-new-countries/). They appear on the Free and Go plans; Plus and above stay ad-free. - **Proactive updates went away.** Pulse, which researched personal updates for you overnight, was [retired in June 2026](https://help.openai.com/en/articles/6825453-chatgpt-release-notes). You can still ask ChatGPT to schedule a daily briefing. - **Price.** Plus is $19.99 on the [App Store](https://apps.apple.com/us/app/chatgpt/id6448311069), and Pro now comes in $100, $200 and $500 tiers. - **Where you live.** Some of OpenAI’s newest features aren’t everywhere: personal Pro accounts [can’t use Dots](https://help.openai.com/en/articles/20001530-getting-started-with-your-dot), its always-on agents, in the UK, the EEA or Switzerland. And there are everyday reasons: wanting an assistant that already knows your Google or Microsoft apps, different privacy terms, a style of answer you prefer, or something that does more than talk. When you’re choosing one to plan your life with, look for five things: **memory** you can see and change, **your calendar and email** connected, **reminders and routines**, whether it **gets ahead of you** or only answers, and what it **does with what you tell it**. ## The alternatives at a glance We looked at the biggest general assistants people use to plan their days, chosen by reach and by what they can do with your calendar, email and reminders. ChatGPT is included, fairly, for comparison. US prices and App Store ratings, checked 25 October 2026.

Voice conversations, photo uploads and image generation are built into the app. Ask, and it will plan a week of meals, a workout or a trip in seconds. **Worth knowing**Ads appear on the Free and Go plans. Free and Go can run three scheduled tasks at a time, and Free runs them in broad windows such as the morning rather than at an exact time. On personal plans your chats can be used to train OpenAI’s models unless you turn off “Improve the model for everyone” in [data controls](https://help.openai.com/en/articles/7730893-data-controls-in-chatgpt).

In the US, [Daily Brief](https://support.google.com/gemini/answer/17077455?hl=en) sums up what needs you each morning from Gmail, Calendar and your chats, and learns from what you mark helpful or dismiss. Gemini Spark, an agent that manages tasks for you, is for Google AI Ultra subscribers. **Worth knowing** [Personal Intelligence](https://support.google.com/gemini/answer/16598406?hl=en), which lets Gemini draw on your connected apps, isn’t available in the UK, the EEA, Switzerland or Nigeria, and Daily Brief is US-only, in English. With Keep Activity on, your chats can help train Google’s models and some are read by [human reviewers](https://support.google.com/gemini/answer/13594961); Google says your Gemini chats aren’t used to show you ads.

[Pro](https://claude.com/pricing) adds research, task handoff and scheduling. **Worth knowing**Searching your past chats is for paid plans. You [choose](https://privacy.claude.com/en/articles/10023580-is-my-data-used-for-model-training) whether your chats help train Claude, and incognito chats never do. Its proactive app, Claude Duet, is a research preview for invited Pro and Max subscribers in the US; we cover it in [our AI agents comparison](https://retenna.ai/articles/proactive-ai-agents-compared). ### Meta AI and Muse Maker Meta Cost Free; Muse has paid plans for heavier use App Store [Meta AI 4.7 from 283K](https://apps.apple.com/us/app/meta-ai/id1558240027); [Muse 4.9 from 350K](https://apps.apple.com/us/app/muse-from-meta/id6760173601) Best for Errands done for you, and help inside WhatsApp Meta has two.

[Muse](https://about.fb.com/news/2026/09/introducing-muse-personal-ai-agent/), launched on 8 September 2026, is a personal AI agent with its own cloud computer. Its [App Store page](https://apps.apple.com/us/app/muse-from-meta/id6760173601) says it manages scheduling conflicts, books reservations, sets reminders, follows up with people, tracks your budget and price drops, and can build a workout or meal plan from data you choose to share, track calories and adjust your training day by day. It checks with you before sensitive actions, such as sending an email or making a purchase. **Worth knowing**Muse is rolling out in the US, is rated 18+, and warns that it “may be inaccurate or take unexpected actions”. Since 16 December 2025, Meta has [used people’s chats with its AI](https://about.fb.com/news/2025/10/improving-your-recommendations-apps-ai-meta/) to personalise the content and ads they see in most regions, though it says chats about health, religion, politics and other sensitive topics aren’t used for ads. Meta says Muse doesn’t share your conversations, or the data on its computer, with its ad systems. ### Microsoft Copilot Maker Microsoft Cost Free with limits; Microsoft 365 Personal $99.99, Family $129.99, Premium $199.99 a year App Store [4.7 from 1.4M ratings](https://apps.apple.com/us/app/microsoft-copilot/id541164041) Best for Homes that run on Outlook and Microsoft 365 In August 2026 Microsoft [merged](https://support.microsoft.com/en-us/microsoft-365-copilot/learning/changes-microsoft-copilot-app) its personal Copilot app with the work one, and the app now calls itself “the AI built for work”. With a personal account you can still chat, create images and upload files for free within limits, and [connect](https://support.microsoft.com/en-us/microsoft-copilot/connecting-microsoft-copilot-to-other-services) Outlook.com, Gmail, Google Calendar and Contacts, OneDrive and Google Drive, so it can find your emails, files and events. With personalisation on, it [remembers](https://support.microsoft.com/en-us/microsoft-copilot/privacy-faq-for-microsoft-copilot) details such as your name, interests and goals. A [Microsoft 365](https://www.microsoft.com/en-us/microsoft-365/buy/compare-all-microsoft-365-products) plan brings Copilot into Word, Excel, Outlook and OneNote, with higher limits. **Worth knowing**Group chats, podcasts and Deep Research were retired for personal accounts on 18 August 2026, and Copilot Tasks moved to Cowork, which needs Microsoft 365 Premium; Personal and Family subscribers lost access. Your conversations can be used to train Microsoft’s models unless you opt out, and if personalised ads and personalisation are both on, your Copilot history helps personalise the ads you see. ### Perplexity Maker Perplexity AI Cost Free; Pro $20 and Max $200 on the App Store App Store [4.8 from 518K ratings](https://apps.apple.com/us/app/perplexity-ai-agent-search/id1668000334) Best for Quick answers and research, with sources Perplexity is an answer engine: every answer comes with its sources.

[Connect Gmail and Google Calendar](https://www.perplexity.ai/help-center/en/articles/12168040-connecting-perplexity-with-gmail-and-google-calendar), and it can search your inbox and see and change your calendar; sending emails and creating events from the Assistant happens in its Comet browser. **Worth knowing**It can only work with one primary calendar, not shared or secondary ones. Perplexity says it may use what’s in your memory to improve its models unless you turn off AI Data Retention. ### Retenna Ours Maker Retenna, that’s us Cost Free early access, with founding pricing for life Where Coming to iPhone, Android and the web; the UK among the first countries Best for Everyday questions and running every part of your life Retenna is more than a chat assistant. It runs its own AI, built deeper for everyday life, and it’s every lifestyle expert in one app: a stylist, a beauty and grooming expert, a personal trainer, a nutritionist, a wellbeing coach, a planner for your days, occasions and trips, and a personal shopper, each with a full space and real tools of its own. They remember what matters to the people you love, share one living model of you, and plan your week together inside your rules. An assistant runs through all of them and answers your everyday questions already knowing you: ask in a few words, and it knows the rest. It shares a calendar and lists with your partner or household, and it brings your history over from other apps, such as your food diary, your workout history and your wardrobe. **Worth knowing**It isn’t out yet. Everything here is what it’s built to do, and early access is open now. Retenna is coming to iPhone, Android and the web. The UK will be one of the first countries, and we’ll confirm the others nearer the time. A general assistant stays useful for broader questions outside everyday life, such as work, research and study. Others you’ll come across: [Grok](https://apps.apple.com/us/app/grok-ai/id6670324846), from xAI, is popular for real-time news and conversation from X. The always-on agents, Grok Bot, OpenAI’s Dots, Claude Duet and Muse, are compared in [Muse vs Dots vs Grok Bot vs Claude Duet](https://retenna.ai/articles/proactive-ai-agents-compared). ## Side by side: what each can do for your life The top rows are where the assistants have caught up with each other. The lower rows are where planning a life needs more than a chat. The key is under the table. Checked 25 October 2026 against each maker’s own pages. Retenna is ours and not out yet: its column shows what it’s built to do. | What it does | Retenna | ChatGPT | Gemini | Claude | Meta AI and Muse | Copilot | Perplexity | | --- | --- | --- | --- | --- | --- | --- | --- | | Remembers you between chats | Yes | Yes | Yes | Yes | Yes | Yes | Yes | | You can see, change or forget what it knows | Yes | Yes | Yes | Yes | Yes Muse | Partly | Yes | | Works with your calendar and email | Yes | Yes | Yes | Yes | Yes | Yes | Yes | | Reminders and routines | Yes | Yes | Yes | Yes Pro | Yes | Yes 365 Premium | Not mentioned | | Gets ahead of you without being asked | Yes | Partly | Yes US only | Yes Duet, US preview | Yes Muse, US | Not mentioned | Not mentioned | | Does things for you, with your OK | Yes | Yes Dots, Pro | Yes Spark, Ultra | Yes | Yes Muse, US | Yes 365 Premium | Yes In Comet | | Your own rules for what it does without asking | Yes | Yes Dots, Pro | Not mentioned | Not mentioned | Not mentioned | Not mentioned | Not mentioned | | A full space for each part of your life | Yes | Not mentioned | Not mentioned | Not mentioned | Partly | Not mentioned | Not mentioned | | Plans each part of your life around the others | Yes | Ask in chat | Ask in chat | Ask in chat | Partly | Ask in chat | Ask in chat | | A reason and an Undo for every plan | Yes | Not mentioned | Not mentioned | Not mentioned | Not mentioned | Not mentioned | Not mentioned | Yes The maker documents it. Condition Only on a certain plan, app or country: Claude’s scheduling on Pro; Copilot’s Cowork on Microsoft 365 Premium; Gemini’s Daily Brief in the US and Spark on Google AI Ultra; Claude Duet as a US preview; Muse in the US; ChatGPT’s Dots on Pro and Business Premium; Perplexity’s actions in its Comet browser. Partly A lighter version: briefings you schedule yourself, now that ChatGPT’s Pulse has gone; turning Copilot’s memory off, which forgets everything at once, rather than changing one thing; or Muse coaching your workouts, meals and sleep in its chat, from data you share, and adjusting your training as your week shifts. Ask in chat It can help if you explain the rest of your week in the conversation. Dash Not mentioned in the maker’s own materials. That doesn’t prove it can’t. Memory, your calendar and your email are now standard. What none of the assistants mentions is a space of its own for your wardrobe, your training, your skin or your sleep, or a reason and an Undo for everything it does. They’re built to answer and to act when you ask, not to run the parts of your life together. ## Where Retenna goes further: four words, three days planned Any of these assistants can help you prepare for an interview if you ask, and the ones connected to your calendar can see it’s there. Retenna is built to take it from there, across your whole life. On Monday night, you type four words: “I got the interview!” **What it already knew**The interview is on Thursday at 10:00, 40 minutes away, and your dentist is at 09:30 the same morning. It has learned that you sleep badly before big days, feel sharpest in the charcoal suit, are flat the morning after a hard session and skip breakfast when you’re nervous. The 09:22 train was late four times this month. And Jo, who hires people for a living, offered to help. Monday 21:05 · just now Your dentist moved from Thursday at 09:30 to next Tuesday, at the same practice. **Why:** it clashed with the interview. Done for you Tuesday 18:00 · the people you love A 30-minute practice run with Jo, before your prep. **Why:** Jo hires people for a living, and offered to help. Waits for your yes · involves Jo Tuesday 19:00 · your assistant 90 minutes of prep, with a one-page brief on the company and the people interviewing you. **Why:** prep on Wednesday night would cost you sleep. Done for you Wednesday 18:00 · your trainer Wednesday’s HIIT class swapped for a 30-minute walk. **Why:** hard sessions leave you flat the next morning. Done for you Wednesday 21:30 · your stylist and wellbeing coach The charcoal suit picked for the morning, a wind-down, and an alarm for 07:00. **Why:** you feel sharpest in it, and you sleep badly before big days. Done for you Thursday 07:30 · your nutritionist and assistant A light breakfast planned, and the 08:52 train, with 25 minutes to spare. **Why:** you skip breakfast when you’re nervous, and the 09:22 was late four times this month. Done for you A clash caught before it cost you the morning, and sleep, training, food, clothes and travel joined up, from four words. So on Thursday, all you have to do is walk in. That’s the difference between an assistant and a team of experts. Each part of your life has its own space in Retenna, with the depth of a dedicated app: your whole wardrobe, with no limit on how much you add, plus your colours, shape and try-on; your training, with sets, reps and weights that change mid-workout, and race plans built back from race day; your meals, recipes and food shop, with meals logged from a scan of your plate, a barcode or your voice; your rest and sleep; your skin, hair and grooming; your days, occasions and trips; your shopping; and the people you love. Each has its own guide, comparing it with the top apps: [stylist](https://retenna.ai/articles/ai-stylist-app), [beauty and grooming](https://retenna.ai/articles/ai-skincare-makeup-app), [personal trainer](https://retenna.ai/articles/ai-personal-trainer-app), [nutritionist](https://retenna.ai/articles/ai-nutritionist-app), [sleep coach](https://retenna.ai/articles/ai-sleep-coach-app), [planner](https://retenna.ai/articles/ai-planner-app), [trips](https://retenna.ai/articles/ai-trip-planner-app), [personal shopper](https://retenna.ai/articles/ai-personal-shopper-app) and [the people you love](https://retenna.ai/articles/ai-birthday-gift-reminder-app). Our [all-in-one lifestyle app comparison](https://retenna.ai/articles/all-in-one-lifestyle-app) shows how it all compares with family and life organisers. In Retenna, try-on from your photos, health features such as counting calories and nutrients, and buying are for adults (18+). Neither Retenna’s experts nor these assistants are doctors, registered dietitians, physiotherapists or therapists, and plans that respect allergies don’t replace checking labels. ## How it learns, and how you stay in charge Every expert shares one living model of you. It learns from what you do, what you choose and what you tell it, and each thing it learns says where it came from, such as “You feel your best in the navy blazer”, from your wear notes, or “Sore for two days after leg day”, from your training log. 1. **Day one** It asks. Your sister is in town on Thursday night: what would you like to do? You plan it, and it remembers. 2. **Within weeks** It suggests. “You always make time for family. Dinner with her on Thursday at 19:00, and move your gym session to Friday lunchtime?” 3. **In time** It decides the way you would. Dinner booked at the place you both like, the gym moved, and the invite for your sister waiting for your yes. **Your rules**You choose what it simply does and tells you about after, and what waits for your yes. Your own plans and places you’ve used before start as done for you; anywhere new and new spending ask first; anything that involves another person always asks first. Every plan comes with the reason and an Undo, and if you keep undoing the same kind of plan, it notices and suggests a rule. **What it knows is yours**You can see, change or forget anything it has learned, and export or delete everything Retenna holds about you. ## What happens to what you tell it An assistant you plan your life with will learn a lot about you. Here’s what each maker says it does with that, and where its most personal features work: - **ChatGPT.** On personal plans, your chats can help train OpenAI’s models unless you turn that off in [data controls](https://help.openai.com/en/articles/7730893-data-controls-in-chatgpt). Ads appear on Free and Go. - **Gemini.** With Keep Activity on, chats and information from connected apps can train Google’s models, and some chats are reviewed by people and kept for up to three years. Activity is deleted after 18 months by default, and Google says chats aren’t used for ads. [Privacy hub](https://support.google.com/gemini/answer/13594961). - **Claude.** You choose whether your chats help train Claude, in its [privacy settings](https://privacy.claude.com/en/articles/10023580-is-my-data-used-for-model-training); incognito chats never do. - **Meta AI and Muse.** Meta AI chats help personalise the content and ads you see, apart from sensitive topics. Muse keeps your conversations away from Meta’s ad systems, and you can opt out of them training Meta’s models. - **Copilot.** Conversations can train Microsoft’s models unless you opt out, and can personalise ads if you allow personalised ads. [Privacy FAQ](https://support.microsoft.com/en-us/microsoft-copilot/privacy-faq-for-microsoft-copilot). - **Perplexity.** What’s in your memory may be used to improve its models unless you turn off AI Data Retention. - **Retenna.** Your Retenna is private to you. Everything it knows is locked to your account and walled off from everyone else’s, on Microsoft Azure’s secure cloud, encrypted when stored and on the way. We never use your information to train public AI models. We never sell your information, and detailed analytics and personalised ads are optional, for adults only, and off unless you say yes. **Where they work**Several of the most personal features are US-first: Gemini’s Daily Brief, Muse and Claude Duet. Gemini’s Personal Intelligence isn’t in the UK, the EEA, Switzerland or Nigeria, and personal ChatGPT Pro accounts can’t use Dots in the UK, the EEA or Switzerland. Check before you pay for a feature. Retenna is coming to iPhone, Android and the web. The UK will be one of the first countries, and we’ll confirm the others nearer the time. ## How to choose Pick a general assistant by the apps you already use. If you want your everyday questions answered by something that already knows you, and the parts of your life looked after, not just talked about, that’s Retenna. It works happily alongside any of them. ### For a general assistant - **ChatGPT** Still the broadest all-rounder, with memory and scheduled tasks Ads on Free and Go. - **Gemini** If your life runs on Gmail and Google Calendar Its most personal features aren’t in the UK or the EEA. - **Claude** Careful help with your inbox, calendar and big decisions Memory on the free plan too. - **Muse from Meta** Errands, bookings and bills handled for you, with your OK US only for now; Meta AI is in WhatsApp everywhere it’s offered. - **Copilot** If you live in Outlook and Microsoft 365 - **Perplexity** Fast answers and research, with sources you can check ### For running every part of your life Ours · coming to iPhone, Android and the web Retenna Every lifestyle expert in one app, running its own AI built for everyday life, each expert with a full space of its own, sharing one living model of you. They answer your everyday questions, plan your outfits, meals, training, rest, days, occasions, trips and shopping around each other, remember the people you love, and work inside your rules, with an assistant across all of them. - Style - Beauty and grooming - Training - Food - Rest - Days, occasions and trips - Shopping - The people you love [Get early access](https://retenna.ai/#join-final) Whichever you pick, check three things first 1. **What it does with your chats**: whether they train its models or shape the ads you see, and how to say no. 2. **Whether its best features work where you live**, and on the plan you’ll pay for. 3. **What it does without asking**, and how easily you can see and undo it. ## How Retenna works About Retenna · that’s us Every lifestyle expert, one mind that knows you. Retenna isn’t a general-purpose assistant with a lifestyle mode. It runs its own AI, built deeper for everyday life, in a complete lifestyle app, with an expert and a full space for every part of your life, and the depth of a dedicated style app, training app, meal planner and planner in one place. Four words, “I got the interview!”, and the dentist moves, prep and a practice run are planned, the hard workout becomes a walk, and the suit, the early night and the 08:52 are sorted, each with its reason and an Undo. What makes Retenna different 1. **Every expert, in one app.** A stylist, a beauty and grooming expert, a personal trainer, a nutritionist, a wellbeing coach, a planner for your days, occasions and trips, and a personal shopper, each with a full space of its own. They remember what matters to the people you love, and an assistant runs through all of them. 2. **One living model of you.** It learns from what you do, what you choose and what you tell it. On day one it asks; soon it suggests; in time it decides the way you would. You can see, change or forget any of it. 3. **Every expert plans together.** They share one picture of your week, so a change in one reshapes the rest: leg day moves, so dinner is ready that night; brows move, so any redness settles before the party. 4. **Everything inside your rules.** You choose what it simply does and what waits for your yes. Every plan comes with the reason and an Undo, and anything that involves another person always asks first. It answers your everyday questions already knowing you, and any assistant above stays useful for broader questions, such as work, research and study. Retenna is coming to iPhone, Android and the web. The UK will be one of the first countries, and we’ll confirm the others nearer the time. Early access is open now.

Gemini if your life runs on Google, Copilot if it runs on Outlook and Microsoft 365, Claude for careful help with your inbox and calendar, Muse if you’re in the US and want errands done for you, and Perplexity for answers with sources. For everyday life, with an expert for every part of it and answers that already know you, we built Retenna. It isn’t out yet; early access is open now. **Is there a free ChatGPT alternative?** Yes. Gemini, Claude, Meta AI, Copilot and Perplexity all have free versions, and Claude’s includes memory and Google connections. The most proactive features usually need a paid plan or a US account. Joining Retenna’s early access is free, and founding members keep founding pricing for as long as they keep their plan. **Which AI assistant is best for planning my week?** The one connected to your calendar. Gemini (Google), Copilot (Outlook and Google), and ChatGPT, Claude and Perplexity (Google) can all read your calendar once connected, and Gemini and Claude can add events when you ask. Retenna is built to plan the week itself: your days, training, meals, rest and outfits around each other, ahead of time. Our [AI planner guide](https://retenna.ai/articles/ai-planner-app) compares the planning apps, such as Motion and Structured. **Does ChatGPT have ads now?** On the Free and Go plans, yes. OpenAI began testing ads in the US in February 2026 and now runs them in 89 countries. Plus, Pro and the business plans are ad-free. **Which ChatGPT alternatives work in the UK and Europe?** Most of the assistants here are offered in the UK, but Muse is rolling out in the US first, and some of the others’ most personal features aren’t available. Gemini’s Personal Intelligence excludes the UK, the EEA and Switzerland, Daily Brief is US-only, Muse and Claude Duet are US-first, and personal ChatGPT Pro accounts can’t use Dots in the UK, the EEA or Switzerland. Retenna is coming to iPhone, Android and the web. The UK will be one of the first countries, and we’ll confirm the others nearer the time. **Is Retenna a ChatGPT alternative?** For everyday life, yes. Retenna runs its own AI, built deeper for everyday life, and answers your everyday questions already knowing you: what to wear to Thursday’s dinner, what to cook with what’s in the fridge, whether to train after two short nights. Behind those answers is every lifestyle expert in one app, with a full space for each part of your life, one living model of you and plans made together. ChatGPT and the other general assistants stay useful for broader questions outside everyday life, such as work, research and study. **Is Retenna built on ChatGPT?** No. Retenna runs its own AI, built for everyday life, so it goes deeper on your style, skin, training, food, rest, plans, shopping and the people you love. It isn’t built on ChatGPT, Gemini or any of the assistants here. It runs privately on Microsoft Azure, and your information is never used to train public AI models. **Can I use Retenna and ChatGPT together?** Yes. Retenna answers your everyday questions and runs your outfits, meals, training, rest, plans and shopping, already knowing you. ChatGPT, or any assistant here, stays useful for broader questions outside everyday life, such as work, research and study.

Everything it knows is locked to your account and walled off from everyone else’s, on Microsoft Azure’s secure cloud, encrypted when stored and on the way. You can see, correct, export or delete what Retenna holds about you, including anything it has learned. If you turn learning on, it learns from what you do and tell it to personalise your own experience, and what it learns stays with your account, never used for anyone else. We never use your information to train public AI models. We never sell your information, and detailed analytics and personalised ads are optional, for adults only, and off unless you say yes. ## Sources - ChatGPT: [App Store](https://apps.apple.com/us/app/chatgpt/id6448311069), [memory](https://help.openai.com/en/articles/8590148-memory-in-chatgpt), [Google apps](https://help.openai.com/en/articles/10408842), [scheduled tasks](https://help.openai.com/en/articles/10291617-scheduled-tasks-in-chatgpt), [release notes](https://help.openai.com/en/articles/6825453-chatgpt-release-notes), [ads in ChatGPT](https://help.openai.com/en/articles/20001047-ads-in-chatgpt), [ads in 89 countries](https://openai.com/index/chatgpt-ads-expands-26-new-countries/), [data controls](https://help.openai.com/en/articles/7730893-data-controls-in-chatgpt), [getting started with your dot](https://help.openai.com/en/articles/20001530-getting-started-with-your-dot) - Google Gemini: [App Store](https://apps.apple.com/us/app/google-gemini/id6477489729), [release notes](https://gemini.google/us/release-notes/?hl=en), [Personal Intelligence](https://support.google.com/gemini/answer/16598406?hl=en), [Daily Brief](https://support.google.com/gemini/answer/17077455?hl=en), [schedules](https://support.google.com/gemini/answer/16316416?hl=en), [calendar actions](https://support.google.com/gemini/answer/15305236?co=GENIE.Platform%3DDesktop&hl=en), [privacy hub](https://support.google.com/gemini/answer/13594961) - Claude: [App Store](https://apps.apple.com/us/app/claude-by-anthropic/id6473753684), [pricing](https://claude.com/pricing), [memory and chat search](https://support.claude.com/en/articles/11817273-use-claude-s-chat-search-and-memory-to-build-on-previous-context), [Google Workspace connectors](https://support.claude.com/en/articles/10166901-use-google-workspace-connectors), [model training](https://privacy.claude.com/en/articles/10023580-is-my-data-used-for-model-training), [Claude Duet](https://support.claude.com/en/articles/17631495-get-started-with-claude-duet) - Meta: [Meta AI on the App Store](https://apps.apple.com/us/app/meta-ai/id1558240027), [Muse on the App Store](https://apps.apple.com/us/app/muse-from-meta/id6760173601), [Introducing Muse](https://about.fb.com/news/2026/09/introducing-muse-personal-ai-agent/), [AI chats and recommendations](https://about.fb.com/news/2025/10/improving-your-recommendations-apps-ai-meta/) - Microsoft Copilot: [App Store](https://apps.apple.com/us/app/microsoft-copilot/id541164041), [Copilot app changes](https://support.microsoft.com/en-us/microsoft-365-copilot/learning/changes-microsoft-copilot-app), [connectors](https://support.microsoft.com/en-us/microsoft-copilot/connecting-microsoft-copilot-to-other-services), [privacy FAQ](https://support.microsoft.com/en-us/microsoft-copilot/privacy-faq-for-microsoft-copilot), [Microsoft 365 plans](https://www.microsoft.com/en-us/microsoft-365/buy/compare-all-microsoft-365-products) - Perplexity: [App Store](https://apps.apple.com/us/app/perplexity-ai-agent-search/id1668000334), [memory](https://www.perplexity.ai/help-center/en/articles/10968016-memory), [Gmail and Google Calendar](https://www.perplexity.ai/help-center/en/articles/12168040-connecting-perplexity-with-gmail-and-google-calendar) - Also mentioned: [Grok on the App Store](https://apps.apple.com/us/app/grok-ai/id6670324846), [OpenAI Dots](https://openai.com/index/introducing-dots/) Spotted something out of date?
