I'd save dozens of YouTube videos and Instagram reels every week, thinking "I'll watch this later" or "this has something useful." Fast forward a few months, and I had hundreds of saved videos that might as well not exist. I'd remember a video had this one tip I needed, but finding it? Impossible. So I built Churo to fix this for myself. What makes it different is the semantic search that actually understands meaning, not just keywords. You can search "productivity tips" and it'll surface that video about morning routines you saved six months ago, even if it never used those exact words. We combine YouTube and Instagram in one library, generate comprehensive AI summaries with chapters and flashcards, and let you chat with your entire collection like it's a conversation. I'm most proud of getting the search to feel magical, that moment when it finds exactly what you were thinking of but couldn't quite describe. Also proud I built this whole thing solo while juggling college, learning everything from vector databases to Chrome extensions along the way. It started as scratching my own itch, but seeing other people finally able to find and use what they save? That's incredibly rewarding.
