[Taffysearch] Add support for multiple video platforms

I built Taffysearch because i needed it for my own research. it turns any YouTube channel into a searchable knowledge base: transcripts, summaries, the kind of stuff you'd need if you're trying to pull insights from hundreds of videos. I was the only user for weeks. used it constantly. didn't think much about selling it. then someone paid. first customer. cool, probably a fluke. this morning i woke up and a YouTuber with 1.7M subscribers signed up to use it on his own channel. second paying customer. i know two customers is nothing. i'm not pretending this is a success story yet. but there's something about that second sale that hits different. the first one could be luck. the second one means someone else independently decided this thing is worth paying for. for anyone here who's shipped something and is still refreshing stripe waiting for that first dollar: it took me weeks of using my own product every day before anyone else cared. the product got better because i was a real user with real frustrations, not because i was "doing customer research." my playbook going into 2026: 1. build something i actually need 2. be honest about whether i'd pay for it myself 3. if it adds real value, tell people about it that last one took me a while. i used to think marketing was annoying. now i think if your product genuinely helps someone, you're doing them a disservice by keeping it to yourself. I think it was steve jobs who said that but stuck with me. two customers. long way to go. but the direction feels right.
