I wanted a way to search across multiple YouTube videos at once, find every time someone discusses a topic, compare how different creators explain the same concept, or pull all mentions of a keyword across a channel's archive.
The interesting part: it uses Gemini's multimodal capabilities to search visually, not just transcripts. So you can find "the whiteboard diagram" or "when he shows the demo", things transcript-based tools completely miss.
Stack: Next.js, Convex, Clerk, Gemini 3 Flash
Would love feedback from anyone who works with video content.
