What does Foam do?
Foam is a VS Code extension that transforms your Markdown notes into a structured knowledge graph. It works by analyzing the wikilinks between your files and building a visual map of how your ideas connect. Instead of just storing files, Foam creates relationships between concepts that both you and AI tools can navigate.
The tool uses standard Markdown syntax with double brackets for linking [[like-this]], and it automatically maintains these connections. When you rename a file, Foam updates all references to prevent broken links. The graph visualization feature shows clusters of related ideas and orphaned notes, helping you identify gaps in your knowledge. The foam-cli tool provides terminal access to your notes with JSON output for automation, and the upcoming foam-mcp integration will allow AI agents like Claude Code to traverse your knowledge graph intelligently.
Foam is ideal for developers, researchers, and writers who work in VS Code and want to organize their thoughts systematically. It helps you build a personal knowledge base that grows with you, using open formats that ensure your data remains accessible regardless of which tools you use in the future. The MIT license and local-first approach mean you own your data completely.
