Similar to DeArrow except with AI right?

Kind of, yes. DeArrow is crowdsourced, and I love that people can submit a better title and pick a real frame from the video. I wanted one step more: the actual answer to the clickbait, right on the thumbnail, without waiting for someone to submit it, since it comes from the transcript. Only works for videos already in YouTLDR's cache for now.

I'm a big fan of SponsorBlock for YouTube too, from the same dev.
