Agents do real work now.
They need somewhere to put it.

Squire Docs gives the work your agents do a shared document your team can read, edit, and correct.

Coding agents write plans, specs, and reports, and most of it ends up in a terminal scrollback or a scratch file nobody else can see. Squire Docs gives that work a shared document: you and your team read it, edit it, and correct it while the agent is still working, and every change keeps its author.

Why open source. The tool that holds your team's specs and your agents' work should be one you can inspect, run, and keep. Squire Docs is MIT licensed, and the hosted service at squiredocs.com runs the same code. For teams that want one, 21st Harmonic offers managed instances.

What we believe

The document is the interface

You shouldn't have to leave your work to use AI. The agent comes to your page.

Agent work is accountable work

Each edit is attributed to whoever made it, human or agent, and can be undone through version history.

Open to any model or agent

Connect any MCP agent, such as Claude Code, Codex, Cursor, Kiro, or Claude Desktop, and bring your own key from Anthropic, Google (Gemini), OpenAI, z.ai (GLM), or OpenRouter. On squiredocs.com, the built-in assistant also comes with monthly AI credits.

Trust by design

Your docs, your infrastructure: open source, markdown export, and self-hosting.

Who's behind it

Squire Docs is built by 21st Harmonic LLC, a small independent software studio. Small team, fast iteration: when you email us, the person who built the product reads it.
