The AI that remembers what people told you.
Most AI memory is what you told the AI. Tracebrain remembers the other side: every person you talk to, in whichever app you talk to them (Telegram and WhatsApp today) - who they are, what you promised each other, and what stopped being true.
Working as a team? Tracebrain is also a second brain for companies: one memory the whole team's conversations write into. See Tracebrain for companies.
What it remembers
Not what you told an assistant. What people told you.
Tracebrain is a personal memory brain that builds itself from your conversations, in every app you have them: one living profile for every person you talk to, a nightly review of what was decided, promised and paid, and your promises turned into tasks, all in Markdown files you own.
People who search for an AI that remembers everything usually mean one of two things. Some want an assistant that remembers them: their preferences, their projects, the context they are tired of repeating. Chat assistants have grown a memory for that, and it works the way you would expect. It holds what you chose to tell it, in the words you used.
The others want help with a different kind of forgetting. Not forgetting themselves, but forgetting other people: the name of a client's partner, the date somebody moved, the thing you promised in a chat three weeks ago and never wrote down. That memory cannot come from what you tell an assistant, because the problem is exactly that you did not notice it at the time. It has to come from the conversations themselves.
That is what Tracebrain reads. It keeps every one-to-one message in the note of the person who sent it, a group's messages in the group's own note, and every night it reads what is new and writes down what is worth keeping. You do not tag, type or summarise anything. The memory grows while you talk to people the way you already do.
One person, one month
Everything it remembers about Amara after four weeks of chats.
An invented client and an invented month. Each week is what the nightly pass added; nobody typed any of it.
Who she is, and the first promise
Week 1 · 14 to 20 September. Amara asks you to build a website for her bakery. By the next morning her profile says she runs a sourdough bakery called Zakwas in Gdańsk, and Reminders carries the promise you made in the same thread: a homepage draft by Friday 18 September, which also lands on your task list. On Friday you send it, she answers "Love it", and the task closes on its own.
The people around her
Week 2 · 21 to 27 September. She mentions that her sister Ifeoma is joining the bakery in October, and that Marek, her accountant, will send you the invoice details. Both appear under Also knows, linked to their own notes. She sends three voice messages in a row and writes that typing is for after closing time: that goes into About, because it is how to reach her. Her birthday, 3 November, fills the empty birthday field.
What she is after
Week 3 · 28 September to 4 October. She is looking for a second shop in Oliwa, and she wants to test a gluten-free loaf in spring. The first is a fact about her life right now, so it goes into About. The second is a hook for a later conversation, so it goes into Ideas.
Something stops being true
Week 4 · 5 to 14 October. On 9 October she writes that she signed the lease in Oliwa. "Looking for a second location" is no longer true, so it moves to Earlier, marked until 9 October, and About gains the new fact: a second shop opening in December. You promise her a quote for online ordering by 16 October; she still owes you the menu photos. Both are open.
Amara Nwosu

Look at what is not on the card. There is no summary of the month, no sentiment score and no paraphrase of every message. A profile is short on purpose: it keeps what you would want to know before you next write to her, and the full conversation stays underneath it, newest first, for the day you need the exact words.
How it remembers
Four rules, so the memory can be trusted.
Every fact has a day
A line in a profile is tied to the message it came from and carries that message's date, not the date it was processed. You can always ask where a fact came from and get an answer.
Ended is not deleted
When a later message shows a fact stopped being true, it moves to Earlier with the day it ended. The past stays readable, and the present stays current.
Your own lines are yours
A line you wrote by hand is never moved or removed by the nightly pass. You can edit or discard any line the pass wrote, on the person's page.
The conversation is never edited
Messages are only ever added to a person's history, never rewritten, so every profile can be checked against what was actually said.
The landscape
AI that remembers, by what it remembers.
Every memory product is built from something. What it is built from decides what it can know about the people in your life.
| Product | Built from | Price | What it knows about other people |
|---|---|---|---|
| Mem | Notes you write, voice notes you record, email you forward; Gmail, Slack and Todoist on Pro | Free; Plus $9 a month; Pro from $29 a month | Only what you wrote down about them |
| Kin | Your conversations with its AI advisors, and a guided journal | Not stated on its site | What you told Kin about them |
| Screenpipe | Your screen and audio, recorded and kept on your computer | Free download; plans not listed on its home page | Whatever crossed your screen or was said near the microphone |
| Tracebrain | Your conversations in the apps you connect; Telegram and WhatsApp today, one-to-one and groups | $20 per month, after 7 days free. No free plan | What they told you, in their words, dated, with what you promised each other |
Read on 18 October 2026 from mem.ai, mykin.ai and screenpipe.com. Each of the three remembers something Tracebrain does not: Mem your own notes and voice, Kin your reflections, Screenpipe everything on your screen. If the memory you are missing is your own thinking, one of them is the better choice.
Asking it
Ask about someone before you write to them.
A memory is only as good as the moment you reach for it. In the Tracebrain app, every person has a page with the profile, the open promises and the latest messages together. Most of the time that page is the answer to “what do I know about Amara?”
The rest of the time you are already talking to an AI assistant. Tracebrain runs an MCP server, so Claude, ChatGPT, Cursor and other MCP clients can read your people, days and tasks when you ask. “Catch me up on Amara before my call” then gets the shop, the lease, the photos she owes you and the quote you owe her, instead of a polite reply that the assistant does not know who Amara is.
Honest limits
What it does not remember.
What was never written
A conversation in a café leaves nothing in a chat, and what is said on a call or in a meeting stays out until those connectors ship.
Channels and bots
Group chats are read when you choose them at setup. Channels and bots are skipped, and so is a Telegram group too big to be a conversation.
Where each channel stands
Live today: Telegram, WhatsApp and Emails. Being built: LinkedIn, Meetings and Phone calls. Planned: Slack, iMessage, Instagram, Signal, Calendar, Voice memos, Agreements, Invoices and Company documents. The connectors page has the detail.
You
It keeps a page about you too, but only from lines you wrote yourself. It is not a diary and does not track how you feel.

The rest of the memory.
A profile of every person is one of three things Tracebrain writes. The other two are a note for every day and a list of what you owe.
AI second brain
Second brains by what they are built from, a finished profile and a day, MCP, and the vault in Obsidian.

Questions people ask about AI that remembers.
Is there an AI that remembers everything?
Not one that remembers everything you did, and the products that come closest record your screen or your microphone all day. What can be remembered completely is narrower and more useful: everything that was written to you. Tracebrain keeps every message from the chats you connect, one-to-one and group, filed under the person or the group it came from, and writes a profile of each person from what they wrote. Nothing in it depends on you remembering to write it down.
What is a personal memory assistant?
An assistant whose job is to remember on your behalf, so you can ask it later. Most of them remember what you tell them. Tracebrain remembers what other people told you: who they are, who they mentioned, what you promised each other and the details worth keeping, like a birthday, a move or a new job. It is a personal CRM you never fill in, kept as Markdown files you own.
How is this different from the memory in a chat assistant?
An assistant's memory is built from your conversations with the assistant. It knows what you chose to tell it, in the words you used. Tracebrain is built from your conversations with people, so it knows what they told you, in their words, on the day they said it. The two work together: through the MCP server, Claude, ChatGPT, Cursor and other MCP clients can read your Tracebrain memory when you ask them about someone.
What happens when something stops being true?
It moves, it does not vanish. Every fact carries the day of the message behind it. When a later message shows that it ended - a new job, a new city, a search that is over - the fact goes to Earlier with the day it stopped, and the new one takes its place. A year later you can still see that Amara was once looking for a shop, and when she found it.
Can I correct what it remembers?
Yes. Any line on a person's page can be edited or discarded, and a line you wrote yourself is never moved or removed by the nightly pass. The messages underneath are never edited: the history is append-only, so a profile can always be checked against what was actually said.
Does it remember passwords and card numbers people send me?
They stay in the message history, where they arrived, and never reach a profile. Card numbers, IBANs, passwords, door codes and one-time codes are masked before any model reads a line, and a proposed fact that contains one is dropped.
Who can read my memory?
Tracebrain is hosted in Germany and keeps one isolated vault per person. To write the profiles, the text of new messages is sent to Anthropic's Claude models and the result comes back. The Privacy Policy names every company that touches anything and what each one sees.
What does it cost?
$20 per month after a 7-day free trial, with no free plan. The pricing page says what is in it, how to cancel, and that the export of your vault keeps working after you stop paying.
Start
Your history is already a month of memory.
A connected app brings its history with it, so the first profiles are written from conversations you have already had. A week is enough to see whether it remembers your people better than you do.
$20 per month after 7 days free. A card is taken when the trial starts; cancel before it ends and you pay nothing.
