Features
Everything Astrakion gives you to build, organize, and ask your own AI brains — grounded strictly in your own knowledge.
Brains
A brain is a named AI knowledge container. Give it a purpose, a tone, and instructions, then teach it what it should know.
- Custom purpose, tone and answering instructions per brain
- Knowledge-only by default — no hallucinated facts
- Make as many brains as you need, each focused on one thing
Knowledge sources
Three ways to fill a brain, all turned into answerable text the moment you add them.
- Notes — paste text, outlines and rules directly
- Documents — PDFs, Word files and images; text auto-extracted
- Resources — paste a link and the page content is fetched in
Ask & chat
A clean conversation with each brain, grounded in its sources and rendered as readable, formatted answers.
- Markdown answers with clickable links
- Conversation history per brain
- Honest 'I don't know' when the answer isn't in the brain
Brain groups
Bundle related brains and ask them as one. Astrakion consults each brain, then synthesizes a single answer in a unified voice.
- One question, many brains, one coherent answer
- See each brain's individual contribution
- Great for cross-domain questions
Shared workspaces
Collaborate with a team. Invite people into a group and pool the brains everyone is allowed to see.
- Invite teammates by email
- Private by default — share only the brains you choose
- Owner controls membership and sharing
API & MCP access
Reach your brains from anywhere — scriptable HTTP API and a hosted MCP server for AI tools.
- Scoped API keys: read-only or full
- MCP server for Claude, Cursor and more
- Read knowledge, ask questions, or push content back
The whole toolkit
Grounded answers
Knowledge-only mode keeps brains honest — they answer from your sources or say they can't.
Private by default
New brains and groups start private. You decide what to share, and with whom.
Open integration
Standard MCP and a simple HTTP API mean your brains work with the tools you already use.
