AI didn't democratize intelligence. It centralized it.
Your context lives on their servers. Your patterns train their models. fai reverses that.
15 supported agents · 1 vault · Your machine
fai is a local tool that captures your AI coding context and carries it forward — across sessions, across tools, across models. Install once, context compounds from day one.
How fai works
Every AI session follows the same four steps — capture what happened, seal it into your vault, synthesize patterns, inject context into the next session. Fully automatic.
CAPTURE
Hooks fire as you code
Automatic. Zero config. Runs in your agent.
History, not snapshots
Your context is plain git — branches, commits, merges. Every session branches off, captures your work, and seals back. You can diff any two sessions or roll back.
If the history of code used to be valuable IP, the history of context is today's Intelligence Transformation's IP.
Plain markdown. Git-backed. Diff it, branch it, audit it. Yours forever.
What happens when you seal a session?
When you end a session, fai seals it — extracting patterns, decisions, and open questions into your vault. Here's what that looks like:
CAPTURES
Active captures highlighted
Everything you discussed, decided, and discovered this session.
Works with everything
fai connects to 15 AI tools through MCP. One vault, all your tools.
