What if your team stopped forgetting?

You're going to think this is just another notes app. It isn't. Brain is a shared memory for your team and every AI they use. Feed it from where you already work — email, Slack, voice, screenshots. It organizes everything into structured notes, then tells you what's gone stale, what conflicts, what's missing, and which decisions are still open. Before you think to ask.

The problem nobody admits

It sounds like your team already knows everything. You just can't find it.

Decisions, ideas and context are scattered across chats, inboxes, docs and people's heads. So every week you re-decide, re-explain and re-discover the same things — and nobody calls it what it is: a tax on your team's attention.

Things you've already lost this month
  • The brief from that client call last month
  • What we actually decided about pricing in February
  • The idea someone shared on Slack at 11pm
  • Why we stopped doing the weekly newsletter
  • The feedback we got the week after launch
  • Where the brand guidelines actually live

Brain remembers it for you.

One private place. Everything your team has ever said, decided, or learned.

Capture from anywhere

If your team uses it, Brain already speaks it.

No new app to live in. Send context from the tools you already use — every channel, every device, every format. Brain handles the rest.

Stay aware

A notes app waits to be asked. Brain notices first.

Stale. Conflict. Gap. Open question. Brain reads its own contents every few minutes and posts what needs attention to your Review queue — before a customer asks, before a teammate misses it.

  1. Day 1

    A blank canvas

    Drop in a few notes, a brief, a Slack export. Brain quietly starts a map of what matters.

  2. Week 1

    Patterns appear

    Clients, projects, rituals and recurring questions surface themselves. Categories you didn't have to create.

  3. Month 1

    It thinks with you

    Ask anything and get answers grounded in your actual work — not the open web.

  4. Month 3

    It starts thinking ahead

    Brain proactively surfaces what you forgot. Follow-ups, stale decisions, unanswered clients, contradictions — quietly flagged before they become problems.

  5. Always

    It works while you sleep

    New brief at midnight? Summarized, tagged and linked to the right project by morning. Your team wakes up to a Brain that moved forward without them.

Agent freedom

Your context is trapped in an AI tool. That was never the plan.

It seems like choosing an AI is a long-term decision now. Because once your team's history, tone and decisions live inside one chat window, moving feels impossible. Brain fixes that by keeping your memory neutral.

Without a central brain
  • Your client history is in ChatGPT's memory — switching means starting over
  • You trained Claude on your tone — but now Cursor is better for coding
  • The team built context in one tool; leaving feels like abandoning a library
  • Every AI promises the world, but your knowledge stays trapped inside it

Switch without losing anything

Brain holds the context. The AI is just the interface. Use ChatGPT today, Claude tomorrow, your own model next quarter — your memory moves with you.

One brain, any agent

Connect Brain to every AI tool your team uses. Each one reads from the same source of truth. No re-training, no re-explaining, no copy-paste.

Future-proof by design

The best AI model six months from now doesn't exist yet. Brain makes that irrelevant — your context is portable, so you are never stuck.

Bring your own AI

Your Brain, inside every AI you already pay for. Coming soon

Brain speaks MCP — the open standard for connecting AI tools to context. Plug it into ChatGPT, Claude, Cursor or your own agent and every answer becomes grounded in your team's actual knowledge.

Model Context Protocol · one source of truth
acme.brain.app/mcp
● Connected · scoped to your workspace
  • Always in context. Ask ChatGPT about a client — it answers from your Brain, not the open web.
  • Permission aware. Each tool only sees what its connected user is allowed to see. RLS, not vibes.
  • Zero copy-paste. Stop pasting briefs into prompts. Your agent has the memory; you just ask.
The pay-off

What a memory actually changes.

A shared memory isn't just nice-to-have. It compounds. Every week, your Brain gets sharper — and so does everything you do with it.

For your team

Onboard in days, not months

New hires absorb years of context instantly. No more 'ask Sarah, she'd know'. Your team's memory is finally a shared resource — not a person.

  • Decisions and their reasoning, preserved
  • Brand voice and playbooks, always at hand
  • No more answering the same question twice
For you

Stop carrying it all in your head

It seems like you're already at capacity. Brain remembers the meeting, the idea, the client preference — so your attention can go somewhere it actually matters.

  • One place to drop anything, from anywhere
  • Ask a question, get the answer with sources
  • Calm mind, sharper focus
For your AI

Make your AI assistant actually useful

Give ChatGPT, Claude or your own agent the missing context about your team. Answers that sound like they came from inside your company — because they did.

  • One-click context for any AI tool
  • No more re-explaining your business
  • Your knowledge never trains anyone's model
Privacy first

Would it be unreasonable to expect your memory to actually stay yours?

Brain holds the most sensitive thing you have — the way your team thinks. We treat it with the seriousness of a vault, not a feed.

Yours. Always.

Your memory belongs to you. Export everything as plain markdown with one click. No lock-in, ever.

Encrypted end-to-endComing soon

Brain is encrypted at rest and in transit. Per-workspace keys, no shortcuts.

Never trained on

Your knowledge never feeds a foundation model. Not ours, not theirs. Full stop.
