Last verified:
What is ODocs.co?
ODocs.co is a collaborative document platform designed as 'the document layer for the agent era,' enabling software engineers, product managers, and AI agents to collaborate on shared documentation. The tool allows users to share Claude Code sessions with product managers, share context between separate agent sessions, and share Claude Code context between engineers. It functions as a multiplayer draw.io and document tool specifically built for human and AI agent collaboration.
Key features include no-login access (similar to draw.io), three ways to create documents (web interface, REST API, and MCP connector), REST API access at https://api.odocs.co/api/docs/{id}, and MCP (Streamable HTTP) integration at https://api.odocs.co/mcp. Documents are identified by UUIDs after #/doc/ in the URL. The platform supports real-time collaboration where humans, product managers, different Claude Code sessions, and agents can all easily edit together.
ODocs.co is specifically for software engineers working with AI coding tools like Claude Code, product managers who need to review engineering context and PRDs, and teams using AI agents who need to share context across sessions. The tool eliminates the need for login while providing API-native and MCP-native integration for seamless agent workflows.

Frequently asked questions about ODocs.co
What is ODocs.co?
ODocs.co is a free, no-login collaborative document system that enables humans and their AI agents to edit documents together. It serves as 'the document layer for the agent era,' specifically designed for software engineers and product managers to collaborate on information from Claude Code or agent sessions, and for sharing context between separate agent sessions.
Do I need to log in to use ODocs.co?
No, ODocs.co requires no login. Similar to draw.io, you can create and use documents immediately without creating an account or signing in. You just click 'create new doc' and start working.
How can I create documents in ODocs.co?
There are three ways to create documents: through the web interface by clicking 'create new doc', via the REST API at https://api.odocs.co/api/docs/{id}, or through the MCP (Streamable HTTP) connector at https://api.odocs.co/mcp.
What is the REST API endpoint for ODocs.co?
The REST API endpoint is https://api.odocs.co/api/docs/{id}, where {id} is the document ID (UUID) that appears after #/doc/ in the URL.
How do I configure MCP for ODocs.co?
MCP configuration is straightforward: add a custom connector with the URL api.odocs.co/mcp (also defined as https://api.odocs.co/mcp). No additional settings are required after adding the connector.
What is the document ID format in ODocs.co?
The Doc ID is the UUID (unique identifier) that appears after #/doc/ in the URL. For example, if the URL is odocs.co/#/doc/abc123-def456, the document ID is abc123-def456.
Who is ODocs.co designed for?
ODocs.co is designed for software engineers working with AI coding tools like Claude Code, product managers who need to review engineering context and PRDs, and teams using AI agents who need to share context across different agent sessions.
Can product managers collaborate using ODocs.co?
Yes, product managers can go into documents, review PRDs, add comments and feedback (like 'Looks good' or 'Let's make changes'), and even use Claude as a thinking partner to critique PRDs and add comments. Engineers can then read those comments back in their Claude sessions.
How do AI agents interact with ODocs.co documents?
AI agents can read ODocs.co documents using either the REST API or MCP connector. Agents don't need historical knowledge or MCP configuration to read documents - they can simply paste the document URL and the system will read it. Agents can also edit documents automatically based on human comments.
Is ODocs.co free forever?
Yes, according to the Hacker News announcement, ODocs.co is a free collaborative doc system. The website does not mention any paid plans or subscription fees, and it operates without requiring login or account creation.
