I built NotesGutter for VS Code, Cursor etc to stop "comment rot." Instead of 20-line comments cluttering your source, you attach rich Markdown notes and Excalidraw diagrams to specific lines via small anchors.

The Workflow:

Markdown Side-Peek: High-fidelity documentation for complex logic. Infinite Canvas: Draw architecture diagrams directly linked to functions. Git-Native: Notes are stored in a .notesgutter folder. They version with your code and work 100% offline. Privacy: No cloud. No tracking. Your data stays in your repo.
