Answers from your documents, with the receipts.

Upload your files, ask in plain language, and get answers that cite the exact passage they came from. Check any claim in one click.

  • No credit card
  • Private workspace
  • Delete your data any time

Every answer cites its sources

Each claim links to the passage it came from, so you can verify it.

Private by design

Your workspace is isolated from every other one at the database query layer.

Delete means delete

Removing a document, project or account removes the data, not just hides it.

Honest about gaps

If your documents don't contain the answer, Brainy says so instead of guessing.

How it works

From a pile of files to an answer you can check

1

Add your documents

Drop in PDF, Word, slides, spreadsheets, web pages or plain text. Brainy reads and indexes them for you.

2

Ask a question

Use everyday language. Brainy searches by meaning and by exact words, then writes an answer from what it finds.

3

Check the source

Open any citation to see the exact passage and page, and decide for yourself whether it supports the answer.

What you get

Built for finding things, not just storing them

Search by meaning and by words

Finds the right passage even when you don't remember the wording, and exact terms when you do.

Cited answers

Numbered citations on every answer, with a references panel showing the supporting text.

Projects and mind maps

Group documents by topic and explore the concepts in them. Click a concept to ask about just that part.

Chat scoped to what you pick

Ask across everything, or limit a question to one concept or document.

Team workspaces

Invite colleagues and give each one a role: owner, admin, member or viewer.

Google Drive, Notion and Confluence

Coming soon

Connect your sources once and import from the folders you allow.

Trust and security

Your documents are yours. We say exactly how we handle them.

We haven't completed a formal SOC 2 audit yet, and we won't pretend otherwise. What we can do is show you how data is isolated, who we rely on, and what happens when you delete something.

Read how we handle your data

Workspace isolation

Every query is scoped to your organisation before it reaches the database.

Sign-in you control

A self-hosted, open-source identity provider using the OIDC standard.

Encrypted in transit and at rest

TLS for all traffic, and encrypted object storage for uploaded files.

A short, public vendor list

Every third party that touches your data is named on the security page.

Questions people ask first

What happens to my documents?

They are stored in your private workspace, parsed and indexed so you can search them. Nobody outside your workspace can query them, and you can delete any document, project or your whole account.

Which AI providers does Brainy use?

Your question and the most relevant passages are sent to the AI providers named on our security page to write an answer. We list each one and what it is used for.

Is Brainy really free?

Yes, while it is in beta. We will announce plans well before anyone is charged, and nothing is billed today.

How accurate are the answers?

Answers are built only from your documents and show their citations. Brainy can still make mistakes, so check the source for anything important.

Is Brainy ready for production use?

It is a beta. It works and we use it, but expect changes and rough edges. Tell us what you find, we read everything.
