What’s on your mind?

A workspace for your writing

Bring your files, editor, Claude and Codex together to explore ideas and write alongside your sources.

Make it sound like you

A preset persona still sounds like someone else. Point the agent at your past posts and edits, and new drafts sound like you.

From files to context

Find references in your documents, PDFs and recordings with text extraction and search. Add search by meaning or build linked wiki pages when your project needs them.

Doc diff ≠ Code diff

Review suggested edits inside your document, with additions and deletions shown in the surrounding prose.

How it works

An idea is enough to start writing. Begin with an empty project or bring your own material; a wiki and search setup are optional.

  1. Open a project

    Open a local folder or create an empty one.

  2. Talk it through

    Explore ideas with Claude or Codex.

  3. Draft and revise

    Write it together, with your agent beside you.
