Mindmap.so is a browser-based free mind mapping tool that connects to Notion.
It imports Notion pages and databases as nodes on a canvas. Users can rearrange the nodes, draw connections between them, and open the full content of any page in a side panel. The tool runs entirely in the browser with no installation, uses a simple interface, creates maps quickly, is free to use, and offers clean export and sharing options.
It is intended for people who already keep information in Notion and need a visual way to map relationships between their existing pages and databases.
