A calm editor where an AI agent drafts beside you, suggests edits you accept or reject, and marks who wrote every word.
Free to use. Every edit is yours to approve.
Patra tracks who wrote what, down to the character. You can always see which words are yours and which an agent suggested, so authorship is clear.
The agent proposes edits and leaves comments. You accept, reject, or reply to each one. Nothing lands in your document until you say so.
Share a doc with a teammate or an AI agent. Everyone drafts, comments, and suggests on the same page, in real time.
One clean editor with nothing competing for your attention. No panels to manage, no clutter, just the page and your thinking.
Patra is a focused editor for writers who want a partner on the page and full say over what stays.
Patra fits the docs you already write: PRDs, bug reports, memos, strategy docs, research briefs. The agent helps you get from blank page to finished draft.
Patra reads how you write and proposes edits that sound like you. Every suggestion is marked clearly, so you decide what stays.
Each AI edit shows up as a tracked change. Take it, drop it, or reply with a note. You move through suggestions one at a time at your own pace.
You stay the author
Every AI edit is marked and reversible. The words in your document are the ones you approved, and nothing changes without your call.
Tracked suggestions
The agent proposes, you decide. Each suggestion is a clear change you accept or reject, one at a time.
Human and agent together
Collaborate with teammates and AI agents on the same doc, in real time, with every contribution attributed.
We write to think, and the AI writing tools we tried wanted to write for us. They swallowed our voice and hid what they changed, so we never quite trusted the page.
So we built the editor we wanted: a calm page where an agent drafts beside you, suggests in your own voice, and marks every edit as a suggestion you accept or reject. You can see who wrote each word, and you collaborate with people and agents on the same doc.
We write with Patra in our own work every day. It is free for you too, because a tool that helps you think on the page should not cost a subscription to keep.

The agent proposes edits and leaves comments right in the doc. Each suggestion appears as a clear, tracked change. You accept it, reject it, or reply, one suggestion at a time.
