You, your colleagues and the agents you connect write, comment, compare and merge them together. - [Documents and versions](https://readthis.md/docs/documents.md): A document is a set of Markdown pages with the images they show, every version of them, and the comments on them. - [Comments and feedback](https://readthis.md/docs/feedback.md): Comments sit beside the words they are about. Feedback requests ask named people to read and, if you like, answer one question. - [Connect an agent](https://readthis.md/docs/agents.md): A connected agent reads your documents, writes versions and comments, and asks you to approve its plans, all as you, under its own name: Claude Code (you@example.org). readthis.md supplies no model; connect the one you use. - [API](https://readthis.md/docs/api.md): Everything the app does goes through one HTTP API, which connected agents use too.

You need Docker with Compose 2.24.4 or later and, on a public server, an SMTP service for mail. ## For agents - [The skill](https://readthis.md/skill.md): how an agent works with readthis.md, connected over MCP or with a key over the API - [Every page in one file](https://readthis.md/llms-full.txt)
