verifiable-archive-indexer — Demo video

Film commissions, cinematheques and production companies sit on years of footage that nobody can search, and cataloguing it by hand takes too long. AI can describe video, but a description with no proof behind it is only a guess. verifiable-archive-indexer indexes video in Spanish and attaches evidence to every claim: a quote from the transcript or a time range in the video. Automatic checks flag what disagrees, an archivist reviews the rest, and the catalog exports as JSON or CSV. You can search the archive and jump to the exact second where something appears. I built it with Spanish speaking archives in Latin America and the Caribbean in mind, although I have only tested it with my own voice. On nine clips I recorded, a full inventory prompt raised object coverage from 21% to 63%, with 92% strict precision on the claims I could decide. The README explains what did not work. Everything in the repository was built during the hackathon.
