Been building something in this space — jsdoc-scribe. It reads your code's actual AST and generates JSDoc comments + a browsable HTML docs site from it — no AI involved, so it's deterministic (same input = same output every time, no hallucinated descriptions).

Features: auto JSDoc generation for JS/TS, static docs site builder, drift detection (know when docs are stale vs code), lint + autofix for JSDoc issues, and a code quality dashboard. 100% local — no network calls, no API key.

Try it without installing: npx jsdoc-scribe src --write

Or install: npm install --save-dev jsdoc-scribe npm: https://www.npmjs.com/package/jsdoc-scribe
