Built for the era of personal AI

Your personal AI agent's memory of you

Your assistant relearns you in every conversation. memorist fixes that. Keep a simple journal, and it quietly becomes a Memory of You — an evidence-backed, portable profile your AI can rely on. Yours to keep, edit, and carry.

The memorist journal timeline showing entries — a walk with Rex, a call with Mom, a rough meeting, drinks with friends, and photos — each tagged with people and moods.

Your AI meets you as a stranger, every single time.

Every new chat starts from zero. You re-explain your tastes, your history, the people in your life, what you're working toward — and the moment the conversation ends, it's gone. The context that would make your assistant actually useful lives nowhere, or worse, in someone else's black box.

memorist gives that context a home you own. A Memory of You — built from your real life, portable to the AI of your choice, and yours to keep. It's the user-owned memory layer that leading researchers say personal AI needs.

The solution

One memory, every assistant.

You feed micro-journaling, mood, life events, relationships, and preferences into your Memory of You, which any personal AI can draw on.
The Memory of You

An evidence-backed picture of who you actually are.

memorist reads your real entries and builds a clear model of you: your preferences, identity, relationships, goals, and the patterns you'd never spot yourself. Not a quiz. Not a guess. Not scraped behavior — a picture drawn straight from moments you chose to keep.

And every belief links to the real entries behind it. Tap one and read the actual moments, in your own words — nothing is a black box, so you always know why it says what it says. If something's off, freeze it, edit it, or remove it on the spot.

It compounds

The longer you keep it, the more it knows — and the more it can prove.

On day one, your Memory is a sketch: a belief or two, each from a single entry. Ninety days in, it's a detailed picture — and every belief is backed by more of the moments that made it true. It doesn't just grow, it grows more sure of itself, with the receipts to show for it.

The only thing you do is keep a journal.

Open the app and write. A thought, a mood, a person you saw, a meal, an intention you don't want to lose. No account, no setup — in and out in under a minute.

That's the whole ask, and it pays back on its own. But quietly, every entry compounds. The habit is the means; the Memory of You is what it becomes.

The memorist app — capturing a quick journal entry in under a minute.
Connect your AI

Connect your AI — on your terms.

When you're ready, connect the AI you already use and let it draw on your Memory of You, so it knows you from the first message. It's a permissioned connection, not a data dump — your assistant sees only the slice you allow, and only until you turn it off, built on an open standard so your memory works with the assistant of your choice.

You choose what it reads

Pick which parts of your Memory an app can see — your tastes, goals, the people in your life, your work, your identity. Everything else stays out of reach.

On until you turn it off

Access is off until you switch it on, and stays on only until you turn it off. In Connected Apps, one tap disconnects any app and its access ends immediately — it's a loan, not a giveaway.

Your boundaries travel with it

Anything you've hidden or marked private never leaves your device, and the boundaries you've drawn travel with every connection — so an assistant knows what not to assume.

See every read

Open Access history and see exactly what each app looked at, and when — never the words themselves, and nothing an app can edit or erase. Sharing your life with an AI should leave a trail you can actually check.

To answer your assistant's questions, memorist keeps a readable copy of just the slice you shared — the one place it holds readable memory. It's only what you allowed, never anything hidden or private, and it stops the moment you turn access off.

FAQ

Frequently asked questions

What is memorist?

memorist is a private pocket journal that quietly becomes a Memory of You — an evidence-backed picture of your preferences, identity, relationships, goals, and patterns, drawn straight from your real entries. It's a portable profile your personal AI can rely on, and it stays yours.

How does it work with my AI assistant?

You connect the assistant you already use — it reads only the topics you allow, and you can turn it off anytime. Your Memory isn't locked into one assistant: point it at the AI of your choice so your assistant starts every conversation already knowing who you are.

What is the Memory of You?

As you journal, memorist builds a curated model of your preferences, identity, relationships, goals, and patterns — drawn from your real entries rather than a quiz or a guess. You can see the moments behind every belief, freeze what's true, edit what's off, or remove it.

How does memorist build my memory?

It reads the entries you keep and turns recurring signals into short, plain-language beliefs, working on your end-to-end-encrypted data. To do that you connect an AI provider — today that's your own Claude or OpenAI key, and your content goes straight from your phone to that provider, never through memorist. With iOS 27, Apple Intelligence can do this on-device. Your Memory builds dynamically as you journal — nothing is hidden, and you can review or remove anything on the Memory screen.

Where does my Memory of You live, and is it private?

Your entries are end-to-end encrypted, and as memorist builds your Memory it never sees your content: the AI that builds it is the provider you connect with your own key. Today that's Claude or OpenAI, with your content going phone → provider directly. With iOS 27, Apple Intelligence can build and read your Memory on-device. The one time memorist holds readable memory is if you choose to connect an outside assistant — then it keeps just the slice you shared (never anything hidden or private), so it can answer that app, and only while access is on.

Do I need my own AI key?

For journaling and Tempo, no — those work the moment you open the app, with no setup. The Memory of You is the part that uses AI: today you connect an AI provider with your own key (Claude or OpenAI), and your entries go straight from your phone to that provider to build your Memory. With iOS 27, Apple Intelligence can build it right on your device — no third-party key needed. Either way, memorist stays out of the middle.

Isn't this a little creepy?

The opposite. You write only what you choose, you see every piece of evidence behind the memory, you own it, and you can delete it. Sensitive parts never have to leave your device — and when you connect it to an AI, you decide exactly which topics it can read, you can see every read it makes in Access history, and one tap cuts it off. It's a memory you build on purpose — not one built about you.

How is my journal protected?

memorist uses end-to-end encryption. Your entries are encrypted on your device before they reach our servers, using a key stored in your iOS Keychain. We can't read them, and neither can anyone else.

Is memorist free?

Yes. memorist is free to download, and you can start journaling right away without an account. An optional membership unlocks the advanced features — including your Memory of You — along with extras like unlimited entries and entry templates.

You just keep a journal.

memorist turns it into the memory your AI will rely on. Free on iPhone, no account required.
