LaterLens screenshot

YouTube's Watch Later playlist has no search. LaterLens fixes that — instant search by title or channel, sorting, and cached results. Uses DOM scraping with programmatic scrolling to index videos (YouTube's API doesn't expose Watch Later). Vanilla JavaScript, no build step, no dependencies.

Free. No paywall. No IAP. No subscription. No ads. No data gathering. Use this extension if it'll be helpful to you.
