Documentation engine for your codebase — hover tooltips, sidebar panel, zero AI in the loop.
ReA indexes your workspace, extracts function signatures and JSDoc, and surfaces documentation exactly where you need it: hover over a function to see its docs, or browse the full project in the sidebar panel. Everything runs locally — no network requests, no telemetry, your code never leaves your machine.
Features
Hover documentation — move your cursor over any function to see its signature, parameters, and description
Sidebar browser — navigate your entire codebase's documented functions in the ReA activity bar panel
Auto-indexing — ReA indexes your workspace on startup (configurable)
JSDoc extraction — existing JSDoc comments are surfaced as-is; undocumented functions get a generated summary
