Peerdraft

Open your Obsidian notes to people, tools, and AI agents

Peerdraft is the collaboration layer between Obsidian and everything else. Connect your notes to other people and devices via real-time Obsidian-to-Obsidian sync or web editor, to tools via RESTful API, and to AI agents via MCP integration. Supports both real-time collaboration and asynchronous workflows. Changes sync automatically whether you're working together or independently.

Note: Only the creator of a shared document or folder (Peerdraft Space) needs an account. Collaborators can access and work on shared content without signing up.
