What you get

Everything you need to teach an AI what you know

Build as many brains as you like, each an expert in exactly one thing.

Focused brains

Each brain is a named knowledge container with its own purpose, tone and instructions — a course assistant, an ops handbook, a client file.

Three ways to add knowledge

Paste notes, upload PDFs, Word docs and images, or drop in a link. Astrakion extracts the text and makes it answerable.

Knowledge-only answers

By default brains answer strictly from what you added — and say so when they don't know, instead of making things up.

Clean chat interface

Ask in plain language and get formatted, readable answers with clickable links — backed by your brain's sources.

Brain groups

Bundle related brains and ask them together — Astrakion consults each and synthesizes one answer in a single voice.

Shared workspaces

Invite teammates into a group to pool brains. Every brain is private by default; share the ones you choose.

How it works

From empty to expert in three steps

1

Create a brain

Give it a name and purpose. Tell it how to answer — formal, friendly, instructor-like, whatever fits.

2

Add your knowledge

Paste notes, upload documents, link pages. The brain learns only from the sources you give it.

3

Ask — anywhere

Chat in the app, or connect the brain to Claude, Cursor and other AI tools through the Astrakion MCP server.

Works with your AI tools

Connect your brains over MCP

Astrakion ships a hosted MCP server. Point Claude, Cursor or any MCP-aware tool at it and your brains become live context — read their knowledge, ask them questions, or push new content back for storage and learning. A read-only key keeps it safe; a full key lets agents contribute.
