Save it once. Ask for it from any AI tool.

New Brain keeps what you and your AI tools learn in one place. Ask from any of them and the answer comes back with its source and date.

Get started free
A desk at the end of a busy week: notebook, sticky notes, a printed agenda and a phone, scattered

It all comes in from where you already work.

You don't have to file anything. Save a thought, connect your apps, and your AI tools save as they go.

Claude

Let's settle it: Pro is $15 a month, billed yearly.

Done. I've saved that as a decision, so your other AI tools will know it too.

Saved to New Brain · Decision · Pricing

Say it or type it
Write a note or speak it. On the desktop app, one shortcut opens a box from any app.
Connect your apps
Notion, Google Drive, Gmail, Slack, Jira and GitHub keep New Brain up to date as things change.
Drop in files
PDFs, documents, screenshots and voice notes. New Brain reads the text in images too.
Record meetings
From your laptop with no bot on the call, from your phone in the room, or upload a recording on the web.
Your AI tools save as they go
When you make a decision in ChatGPT or Claude, the tool saves it to New Brain.
Bring your chat history
Import your ChatGPT and Claude exports so nothing you've already said is lost.
Obsidian and folders
The desktop app watches an Obsidian vault or a folder and brings in changes.

You stay in charge of what it knows.

Each saved thing is one of five kinds: a decision, a fact, a status, a preference or a lesson. Each keeps a source and a date.

  • To check. Anything an AI tool worked out on its own waits here until you keep it, fix it or remove it. Things you said straight out are saved right away.
  • Groups, not floods. Facts from a connected app arrive as one group, like "12 facts from the Product Notion space", so you can keep them all at once or look through them.
  • History kept. When something changes, the old version is marked as replaced, never erased. You can see what was true when.
  • "These two don't match." New Brain spots repeats and things that disagree, and offers a fix.

Northwind wants invoices in euros from November.

KeepFixRemove

12 facts from the Product Notion space

Ask here, or in the AI tool you already use.

Ask "What's my day rate for Northwind, and has it changed?" and get "€900 since 3 September. Before that €800." Each line links to the email it came from. If New Brain has nothing on a question, it says "I don't have anything on that."

  • In your AI tools. ChatGPT, Claude, Cursor and the rest look things up in New Brain and write the answer with its source.
  • Pick up where you left off. Back on a project, see where you were, what changed since and what's due.
  • About you. A short guide to who you are and how you like to work, drafted from three questions. Every AI tool reads it first.
  • Saved instructions. Write "how we write a client update" once, and any AI tool can follow it.
  • Weekly digest. What changed and what's due, plus a check for facts that have gone stale.
  • The Map. Everything you've saved as dots around a centre, by area or over time.

ChatGPT

What's my day rate for Northwind, and has it changed?

€900 since 3 September. Before that €800.

Gmail · Rate for Q4 · 3 Sep

What it looks like in a normal week.

  1. Monday, Claude.

    You settle pricing: "Pro is $15 a month yearly." Claude saves the decision. The old $12 idea is marked as replaced.

  2. Tuesday, Google Meet.

    You record a call with a client from your laptop. The summary, two decisions and three action items wait in To check. You keep them all.

  3. Wednesday, ChatGPT.

    "What did we decide about pricing on Monday, and what did the client agree yesterday?" ChatGPT answers both, with links to the Claude chat and the moment in the recording.

Example. Names and times are made up.

A whiteboard after a meeting: the plan still on the left, the rest wiped to faint grey ghosts

Questions, answered.

Do I have to sort things into folders?
No. New Brain files each thing as one of five kinds and links people and projects that show up under different names, like an email name and a Slack handle.
What if an AI tool saves something wrong?
If the AI worked it out on its own, it waits in To check. If it's already saved, fix it and the old version stays in history. You can also set any AI tool so everything it saves waits for you.
What does "source and date" mean?
Every answer says where it came from (an email, a document, a meeting, an AI chat) and when, with a link to open it.
