Thousand

Thousand is a documentation engineering platform that treats a markdown repository as the single source of truth for your team's docs. Every folder in the repo has its own access rules, so each reader sees only what they're allowed to see — whether they're a human or an AI agent. The workspace is a live git repo, and every edit becomes a named commit. No export, no second copy to drift.

The platform syncs docs from your code repositories on every commit, stamped with the source. You can set folders to read-only or two-way sync, so an edit in Thousand lands back in the repo as a commit under your name. Non-technical team members can edit markdown through a document editor without ever seeing raw markdown. Documents can be shared as links that open in a browser with no sign-up required, and comments live beside the file, not inside it. Office files and PDFs render in place and are searchable by their content.

Thousand is built for engineering teams, technical writers, and product managers who need a documentation system that works for both code-savvy and non-technical colleagues. It's especially useful for teams that want to give AI agents access to documentation without exposing the entire repo. Real-world use cases include maintaining internal knowledge bases, collaborating on product specs, and sharing board decks with external stakeholders.
