Write first. Revise with AI.

AI that writes in
your voice.

Prose builds a voice profile from your own writing, then suggests edits word by word. Accept what helps, reject what doesn't. Your files stay on your disk, and nothing you send the AI is stored or trained on.

An editor that edits with you

Local-first, private, and built around the diff, not the chat window.

Word-level diffs

Suggestions land inline, word by word. Accept or reject each change on its own, in source or WYSIWYG mode.

Discuss, then diff

Talk through the draft. Every file keeps its own thread. When you're ready, the rewrite lands straight in review: inline diffs for small changes, side-by-side for a full pass.

Private by default

Your files stay on disk as plain markdown. Nothing you write is stored on our servers, and no model provider retains it or trains on it.

Writing voices

Rewrites that sound like you

Drop in a few writing samples and Prose builds a voice profile: your tone, your sentence rhythms, your signature phrases. Every AI rewrite then adopts that voice, across every preset.

  • Voice profile generated once from your samples
  • Applied to Improve, Shorten, Translate, and Custom alike
  • Switch voices with a click
  • Edit the profile yourself; it's just a document
