What’s on your mind?

Your agent,
inside your knowledge base

It works side by side with you on your docs, and keeps your knowledge base up to date as it grows.

Side by side with your agent

Your docs stay open beside the chat. When your agent edits one, Review shows each change inside the prose, so you can undo or keep it.

Your knowledge base, kept up to date

Ask your agent to file new material, update your notes and link them back to their sources. It reads PDFs, Word docs and scans too, with the text extracted on your computer.

Bring the agent you already use

Claude, Codex or Antigravity runs on your own subscription, and we charge nothing extra. Pick a persona or write your own, then point the agent at your past posts so drafts start closer to your voice.

How it works

An idea is enough to start. Begin with an empty folder or bring your own material.

  1. Open a project

    Open a local folder or create an empty one.

  2. Talk it through

    Explore ideas with Claude, Codex or Antigravity.

  3. Draft and revise

    Write it together, with your agent beside you.
