I'm Steve, a solo dev who's spent way too many nights rage-closing YouTube tabs 8 minutes into a video that had 30 seconds of actual signal.
That frustration turned into Focal a browser extension that gives you a WATCH / SKIM / SKIP verdict on any YouTube video before you click play. Hover a thumbnail, it reads the transcript, scores information density, and pulls out timestamped bullets and key moments. You can even apply a "lens" like just the steps or no fluff to filter for exactly what you're there for.
I built it mostly for my own ADHD brain, but it turns out a lot of people have the same "is this 20-minute video actually worth it" problem.
