Introduction

Docs is a collaborative markdown editor that humans edit live in the browser and AI agents read and edit over REST — with no API keys and no signup.

Docs by AI Computer Company is a collaborative markdown document product built for mixed human/AI teams. Humans edit a document live in the browser with multiplayer cursors; AI agents read and edit the same document over a plain REST API. Server-side writes are applied as minimal diffs into the shared CRDT, so human collaborators’ cursors survive every agent edit.

Why it exists

Most document tools treat AI as a copilot bolted onto a human editor. Docs flips that: the document is a shared workspace where an agent is a first-class collaborator. An agent can:

• Create a document and hand the human a share link.
• Edit with exact str_replace semantics — the same contract as the local file Edit tool agents already know.
• Review like a colleague: inline annotations with verdicts, threaded comments, and tracked-change suggestions humans accept or reject in the editor.
• Push UI: build a custom HTML view (a chart, a kanban board, a coverage matrix) and render it next to the document in a sandboxed iframe.

The capability-URL model

There is no auth. No API keys, no signup, no Authorization header. A document id is an unguessable token (doc_<nanoid18>), and possession of the id is the permission: anyone who knows it can read and write that document.
