Best AI for personal use: which one for which job, and the job they all leave to you
You want an assistant for your own life, not your work. This guide sorts ChatGPT, Claude, Gemini, Copilot and Siri by the job you would hand them, from each company's own pages read on 12 October 2026, then turns to the job most lists skip: keeping track of the life admin you already have.
You are choosing an assistant for yourself: the letter to the landlord, the trip in April, the form from the school, your parents' appointments. Most lists answer a different question, which tool a developer or a sales team should buy. This one stays at home. Everything it says about ChatGPT, Claude, Gemini, Copilot and Siri comes from those companies' own pricing and help pages, read in a browser on 12 October 2026. Equerry, the personal assistant from the company that publishes this guide, comes up near the end, for one job only. If you are choosing an assistant for your work, our comparison of AI executive assistants is the page for that.
The five, side by side
US prices as each company publishes them. Pricing pages often show your local currency, so the figure you see may differ.
| Assistant | Free plan | Paid plans (US, as published 12 October 2026) |
|---|---|---|
| ChatGPT (OpenAI) Web, iPhone, Android | Yes. "The free version of ChatGPT is available to everyone." The pricing page lists it with "Limited memory and context". | Go: "In the US, Go is available for $8 per month" (OpenAI, 16 January 2026); the pricing page adds "This plan may include ads." Plus: "$20/month (billed monthly)". Pro: a higher tier with "Your choice of 3 usage tiers". OpenAI's FAQ: "Go, Free, and Plus plans are designed to be used by individuals." |
| Claude (Anthropic) Web, desktop, iPhone, Android | Yes. The free plan's card lists "Memory across conversations". | Pro: "$20 if billed monthly", or "$17 Per month with annual subscription discount ($200 billed up front)". Max: "From $100" a month. |
| Gemini (Google) Web, iPhone, Android, inside Google apps | Yes, with a Google Account. | Google AI Pro: $19.99 a month or $199.99 a year, with "Family sharing with up to five others". Google AI Plus sits below it and Ultra above it; both are priced on Google's page. |
| Copilot (Microsoft) The Copilot app and Microsoft 365 apps | Yes, with limits. Microsoft's words: "a limited free version of Copilot". | Microsoft 365 Premium: $19.99 a month or $199.99 a year. Microsoft 365 Personal ($9.99 a month) and Family ($12.99 a month) appear on the same page. |
| Siri AI (Apple) The Siri app on iPhone with iOS 27 | No plan to buy. It needs an Apple Intelligence iPhone: Apple's guide says "iPhone 15 Pro, iPhone 15 Pro Max, or iPhone 16 model or later". | None. Apple says "Siri AI is rolling out in English" and that it "will not be initially available in the EU on iOS, iPadOS, and watchOS." |
Best AI for everyday use: which one for which job
A guide, not a ranking. For most everyday jobs any of the four chat assistants will do; the honest differences are plan limits and the account you already have. Where a company's page says something specific about a job, it is quoted.
| The job | Where to start |
|---|---|
| A letter, a complaint, an awkward reply | Any of the four chat assistants. Paste what you received, say who you are and what you want, and ask for a plain version you would actually send. On a compatible iPhone, Apple's guide points to "Write with Siri". |
| Planning a trip | Any of the four. Give it the dates, who is going and what they hate, then push back on the plan. Apple's own example for Siri AI is "Write a day-by-day itinerary for a 3-day trip to New York." |
| Explaining a bill, a form, a letter from the council | Photograph it and ask what it means, what you must do, and by when. Uploads are rationed on free plans; ChatGPT's free plan lists "Limited messages with uploads". Siri AI has "Ask Siri about what's on your screen". |
| Help with homework | Any of the four explains a topic; ask for the method, not the answer. ChatGPT's plan comparison lists a "Study mode". |
| Photos and images | Making them: all four, with limits by plan (ChatGPT's free plan: "Limited image creation"). Finding your own: Siri AI "can search your photos, mail, messages, calendar, and more". |
| Recipes and the house | Any of the four, and this is where telling it about yourself pays off. Google's help page example for Gemini is "Remember that I am vegetarian." |
| Finding something already on your phone | Siri AI, on a compatible iPhone, because it searches what is already there. The chat assistants reach your mail only if you connect it (OpenAI lists "content from connected apps, such as Gmail" among ChatGPT's memory sources). |
What each one keeps between conversations
Say the passport renewal notice arrived in June and you ask about it in November. What happens depends on two things: whether the notice reached the assistant at all, and whether you can see what it kept. From the companies' pages, read on 12 October 2026:
| Assistant | What reaches it | Where you see it, and how you delete it |
|---|---|---|
| ChatGPT | "When Memory is enabled, ChatGPT can remember relevant preferences and details from your chats and other available sources." The sources OpenAI lists: "past chats, saved memories, custom instructions, files in Library, content from connected apps, such as Gmail". So the notice reaches it if you pasted it, uploaded it, or connected the mailbox it sits in. Plans differ: "Limited memory and context" on Free, "Expanded memory and context" on Plus. | Settings → Personalization → Memory. The memory summary "is a high-level view of information that ChatGPT may use to personalize responses. It does not necessarily include every detail or source that Memory can reference." You can correct it, and "You can also ask ChatGPT what it remembers about you." The older Saved memories setting keeps "a more explicit list of individual memory items" instead. |
| Claude | "Claude saves memory as a set of individual topics as you chat." Memory "is on by default for Free, Pro, and Max plans". The memory page we read does not describe uploads as a source. | Settings → Memory. "Everything Claude remembers is listed under Topics." "Select any topic to read it, then use the edit icon to change it or select "Delete" to remove it." |
| Gemini | "Gemini will remember the information or instructions you share with it, even in new chats", Google's example being "Keep track of this: my annual review is on March 15th." Memory of past chats needs you to be 18 or over, a personal Google Account and Keep Activity on; the remember-and-manage feature needs a Google AI plan and is "Only available in the US". | Personal context (in the app: Menu → your profile picture → Personal context; on the web: Menu → Settings & help → Personal context), where Memory turns on or off. To remove something it remembered, Google says to "delete all chats with this info from Gemini Apps Activity". |
| Copilot | Saved memories from your chats. | Settings → Personalization, then Manage next to the Saved memories toggle. "Select the Delete icon next to any memory to remove it from Copilot Memory", or use Delete all memories. "Turning off Copilot Memory doesn't automatically delete already saved memories". |
| Siri AI | What is already on the phone: "Siri AI can search your photos, mail, messages, calendar, and more". The Siri app keeps conversations so you can "pick up where you left off". | Settings → Siri → Keep Conversations. Apple's note: "If you choose 30 days or 1 year, older conversations are permanently deleted." |
The pattern: every one of them remembers what you tell it, and most can see more if you connect an account. None of them opens the renewal notice unless you put it in front of them, by pasting, uploading, connecting the mailbox, or, on a recent iPhone, because it already sits in Mail. For your own life the question is less "which remembers most" than "what do I want to hand over, and can I see what it did with it".
The job most lists skip: keeping track of the life you already have
Most of the admin in a life is not a chat. It is a renewal notice that arrives eleven months early, a school letter with three dates in it, an appointment confirmation for your mother, a warranty card in a drawer, a thing the pharmacist said on the phone. It arrives in five places and is needed in none of them, until it is.
Equerry is built for that job. In the words of its App Store page: a personal concierge who keeps track of your life. Tell it what to keep watch on, from the passport renewal to Mom's appointments, and get your day laid out each morning. The same page adds one line, because the word concierge promises more than this: it never sends, buys or books on your behalf.
Getting things into it works the way you already use an iPhone:
- Forward the email, or CC it. The renewal notice, the school letter, the appointment confirmation: forward it to your own Equerry address (something like
sam@mail.getequerry.app). For a thread that will keep going, with the school or the contractor, CC the address instead, and later replies keep arriving as long as people keep it on the thread. The original stays in your own mailbox, and it never asks for your inbox. What Equerry remembered from it is listed in Settings → Your memory, each line marked as from that email, and you can delete any line. - Share a PDF, a photo, a link or some text from any app with the share sheet: the warranty card you photographed, the clinic's web page, the lease.
- Type a note, or record a voice note in Equerry. "The pharmacist said the new dose starts Monday." When an answer draws on a note you saved, it carries a source chip: tap it to see the passage Equerry used and open the original.
- Ask later, in plain words. "When does the passport expire?" is answered from what you sent it, not from the whole internet.
"Keep watch" and "your day laid out" are Routines you set up, and they do exactly this:
- A Watcher runs on a schedule you pick (hourly, every six hours or daily) over your archive, the web or both, and pings you when a run finds something new on its topic.
- A Reminder is a push on a date you pick, once or repeating, with the text you wrote.
- A Morning Brief is the day laid out each morning. It is a Routine you set up, not something that is on by default.
It never sends, buys, books or calls on your behalf. Here is what it does look like:
| What you send | What you ask | What you get back |
|---|---|---|
| The passport renewal notice, forwarded from your email. | "When does the passport expire, and what do they need from me?" | The date and the list, taken from the notice you forwarded. What it kept from that email is listed in Settings → Your memory, marked as from it. |
| A photo of the dishwasher's warranty card, shared from Photos. | "Is the dishwasher still under warranty?" | The answer, worked out from the dates on the card you shared. |
| A note you typed after the clinic called about your mother. | "When is Mom's next appointment, and what should she bring?" | The answer with a source chip to your note; tap it to read the passage it used. |
If you also set a Reminder for the appointment, the push arrives on the date you picked, with the words you wrote.
Four fair objections, answered with what it does and does not do
These came up, almost word for word, in a public thread about what ordinary people are supposed to do with assistants.
"My life's not complicated." Then it is one place for the five things that are: the passport, the car service, the school forms, your parents' appointments, the warranty. Forwarding is the whole setup. And if there is nothing you need to keep track of, you do not need something to keep track of it. That is a fair place to land.
"I don't need an agent to book my hair appointment." Good, because it books nothing. It never sends, buys, books or calls on your behalf. It keeps the confirmation you forwarded, answers when you ask about it, and if you set a Reminder, it pings you on the date you picked with the words you wrote. The appointment is still yours to make.
"It's a time suck." There is nothing to organise, tag or file, no folders to design and no accounts to connect. You send it the thing when it arrives, which takes as long as a forward, and ask when the question comes up. The time it saves is the hunt.
"Not for people who can't reboot a phone." If you can forward an email and type a question, you can use it. Setting up asks for this: sign in with Apple; answer five quick questions in a chat so it knows who you are; pick the address you will forward things to (a name you choose, then @mail.getequerry.app); add that address to your contacts, or skip; pick one helper to start with (a morning brief, a watcher, a reminder, or one you describe), or skip that too; and say yes to notifications if you want the pushes. You need to be 18 or older.
Pro is $39.99 a month or $329 a year in the US. One subscription covers a household: Pro works with Apple Family Sharing, in the App Store description's words "with up to 5 additional family members on one subscription", each with their own private archive, and the group shares one monthly usage limit.
Keep ChatGPT, Claude, Gemini, Copilot or Siri for the letter, the trip and the homework; they are good at it and most of it is free. Use Equerry for the job they leave to you: the handful of things in your life that arrive early and matter late.

Frequently asked questions
What is the best AI for personal use?
There isn't one winner, because the jobs differ. For writing, planning and explaining things, the four chat assistants (ChatGPT, Claude, Gemini and Copilot) all do the work, and the differences that matter are price, where it runs and how you control what it remembers; the tables on this page lay those out from each company's own pages, read on 12 October 2026. For finding something already on your iPhone, Siri AI searches your photos, mail, messages and calendar on a compatible model. For keeping track of your own paperwork, the renewal notice, the school letter, the appointment, the useful question is what reaches the assistant and whether you can see what it kept. Equerry, the personal assistant from the company that publishes this guide, works only from what you send it and lists what it remembered so you can delete any line.
Which AI is best for everyday life?
The one you will actually open. If you live in Google apps, Gemini has a free plan with a Google Account, and Google AI Pro can be shared "with up to five others" in a family group. ChatGPT's free plan is "available to everyone" and OpenAI's help center lists Plus at "$20/month (billed monthly)". Claude's free plan card lists "Memory across conversations". Copilot has "a limited free version" and comes with Microsoft 365 plans. Siri AI comes with iOS 27 on a compatible iPhone (an iPhone 15 Pro, 15 Pro Max, iPhone Air, or any iPhone 16 or later), in English first. For the everyday admin itself, the renewals and appointments, see the section on keeping track of the life you already have.
Is ChatGPT or Gemini better for personal use?
For writing, planning and explaining, they overlap heavily, and neither company's pages make a claim about personal life that the other doesn't. The differences you can check: plan structure (OpenAI says its Go, Free and Plus plans "are designed to be used by individuals", while Google AI Pro offers "Family sharing with up to five others"); memory controls (ChatGPT under Settings → Personalization → Memory, with a summary you can correct and the option to ask it what it remembers; Gemini under Personal context, where removing something it remembered means deleting the chats that contain it from Gemini Apps Activity); and age (Gemini's memory of past chats needs you to be 18 or over). Pick by the account you already live in.
Can an AI assistant keep track of my appointments and renewals?
Yes, if the appointment reaches it. All five remember what you tell them in a chat. ChatGPT can also draw on "content from connected apps, such as Gmail" if you connect them, and Siri AI searches the mail and calendar already on a compatible iPhone. What none of them does on its own is receive the confirmation email. With Equerry you forward the confirmation or the renewal notice to your own Equerry address, ask about it later in plain words, and, if you want a nudge, set a Reminder for the date you pick, with the words you wrote. It never books or changes the appointment.
Do I need an AI assistant if my life isn't complicated?
Probably not for the chat part, and maybe not at all. If you have nothing you need to keep track of, you do not need an assistant to keep track of it. The case for one is narrower than the ads suggest: a handful of things, the passport, the car service, a parent's appointments, the school forms, arrive months before you need them and sit in the wrong place when you do. If that is you, the whole setup is forwarding an email. If it is not, keep your money.
Will an AI assistant book things for me?
Some products are built to act for you, booking, calling and paying from accounts you connect. Those are a different category, and our comparison of AI executive assistants covers them for work. The five chat assistants on this page are mostly for asking and writing; what each one does on your behalf changes by plan, so read the plan page before you count on it. Equerry never sends, buys, books or calls on your behalf. It keeps the confirmation you forward, answers questions about it, and reminds you on the date you pick.
