One memory for every AI. You decide what it remembers.
Harakka keeps what your AI learns about you in notes you can read, correct and take with you. Claude, ChatGPT or whatever comes next remember the same things - and nothing is saved until you say yes.

Keep it for the small talk. Keep Harakka for what matters.
The memory inside each AI app is convenient, but you can't see much of it, you can't move it, and it keeps whatever it guessed.
Built-in AI memory
- Saves on its own, in the background
- Locked to one app
- A list of fragments that is hard to review
- Old facts stay true forever
- The same thing ends up saved three times
Harakka
- Your AI proposes, you approve in one tap
- Works in every app that speaks MCP
- Real notes in folders, with full history
- Flags what is out of date and asks you to check
- Checks for an existing note before saving a new one
Three steps, and then you just talk.
Connect your AI
Add Harakka as a connector in Claude, ChatGPT, Cursor or any MCP app. You choose what each one may see and do.
Talk as usual
When something lasting comes up - a decision, a date, a preference - your AI looks for the right note and proposes a line.
Approve what's true
One tap and it lands, dated, in the right note. Say no, and it won't keep coming back. Every AI you use reads the same memory.
Not a black box. A memory you can open.
Everything your AI remembers lives as ordinary notes - in folders, with tags, tables and links. Read them, correct them or write in them yourself, at your desk or on your phone.
Everything your AI wants to remember lands here first. Approve a fact in one tap, and fix a contradiction with the exact line in front of you.
Every edit is a version with a name on it, human or AI. See exactly what changed, and undo it in one click.
Tables for anything with numbers, tags across folders and [[links]] that work both ways.
Press ⌘K on the desktop or tap Search on the phone. It finds the note even when you don't remember the exact words.
Attach receipts, policies and PDFs. Your AI reads the text in them; everything else is there to download.
Also: tap any line to edit it · pin what you're working on · installs on phone and desktop · reads offline
A memory you can trust, and take with you.
You decide, and it tends itself
Everything your AI wants to remember waits in a queue. Meanwhile Harakka keeps the memory from rotting while you're busy.
- An approval queue. Facts are a tap each, or approve a whole batch at once.
- Contradictions come with the fix. You see the exact line as it stands and as it would read.
- Knows when it's stale. Review dates bring a note back for a quick "still true".
- A nightly check-up. Duplicates, summaries that fell behind, missing links and notes nobody finds.
- No duplicates. Before anything new is saved, your AI is pointed to the note that already exists.
- Old facts become history. Give a trip or a price an end date, and afterwards it reads as history.
Yours, on your terms
Decide what each AI may see and do, share parts of it with the people you live or work with, and bring along what other AIs already know.
- Permissions per AI. Read, propose or edit - for everything or only chosen folders.
- Every AI signs in. Disconnect one in Settings and it's out on its next request.
- Shared folders. Your partner gets their own login and their own AI, to those folders only.
- Bring your old memory. Paste what ChatGPT or Claude remembers; pick where each line goes.
It writes the way you want
- Rules per folder. What belongs there, what doesn't, and how to write it. Every AI gets them with every note.
- Precise edits. Your AI changes the section or row that needs it, not the whole note.
- Tidy tags and links. Spelling variants merge as you write; [[links]] work both ways.
It stays yours
- History and undo. Every change is a version: who made it, human or AI, and what changed.
- Plain Markdown. Export any time, or back up every night to a Git repository of your own.
- Search that forgives. Finds the note even when you don't remember the title or the exact word.
Any AI that speaks MCP.
MCP is the open standard AI apps use to connect to tools. Harakka is an MCP server with sign-in, so connecting is a matter of pasting one address.
In ChatGPT, custom connectors need developer mode, and on Plus and Pro they can read but not propose. Harakka's own app works in any browser and installs on your phone and desktop.
Good to know.
Do I have to stop using my AI's built-in memory?
No. Let it keep the small things. Harakka is for what you want to be able to read, correct and bring along when you switch or add an AI.
Where is my data stored?
In a Postgres database, as plain text you can export as Markdown at any time. You'll be able to run Harakka on your own account, so the data never leaves infrastructure you control.
Can my AI change things without asking?
Only if you let it. Each connection is set to read, propose or edit. With propose, nothing changes until you approve - and every edit, by anyone, can be undone.
What does sharing a folder actually share?
Only the folders you pick, and anything you later put in them. The other person never sees your other notes, your queue or your settings, and their AI gets no more than they do.
What will it cost?
Pricing comes with launch. People on the waitlist hear first and get in first.
Why the name?
Harakka is Finnish for magpie - the bird that collects the things worth keeping. It's the one sitting on the k.
Give every AI the same memory - one you can read.
Harakka is in use every day and opening to a small group first.
