Ampersand is a local markdown editor that suggests edits as inline diffs. Accept what helps, reject what doesn't — your words stay yours.
Local-first, model-agnostic, and built around the diff — not the chat window.
Suggestions land inline, word by word. Accept or reject each change on its own, in source or WYSIWYG mode.
Powered by Ampersand Cloud — no keys to juggle. Switch models per task without leaving the document.
Your files live on disk as plain markdown. No accounts to read, no lock-in to leave, no sync to wait on.
Drop in a few writing samples and Ampersand builds a voice profile — your tone, your sentence rhythms, your signature phrases. Every AI rewrite then adopts that voice, across every preset.
Free forever as a markdown editor. Plans turn on managed AI models and monthly credit.
