Local-first, private semantic search over a large personal VIDEO archive — find the moment, person, object, or spoken phrase across years of family/GoPro footage without uploading it to anyone
People with terabytes of personal video (GoPro, phone clips, family archives) want to search the contents the way photo tools already let them search images: 'find the clip where the kid blows out the candles', by object, face, scene, or spoken word — running locally on their own machine, not a cloud service. Photo managers nailed image search but treat video as a single thumbnail frame, and the pro tools that can do it are editing suites, not household media libraries.
Don't compete with editors — the wanted product is a 'Photos app for video' that runs offline. The real moat is making indexing cheap and tolerable (smart frame sampling instead of every frame, and suppressing Whisper's non-speech hallucinations); whoever makes a non-technical person able to point it at one folder and get useful results overnight wins, because Immich users have been asking for exactly this for over a year and the project keeps deferring it.

Image search is solved (Immich, Google/Apple Photos), but video content search is a stubborn gap: self-hosted photo tools index video as a thumbnail, and the tools that can search video content are pro editors. Open questions builders must beat are processing speed (commenters note it can't take longer to index than to watch) and Whisper hallucination on non-speech audio.
