Backcat’s timestamped answer machine
A web app that turns YouTube videos into timestamped concepts, people, and cited answers you can research across collections.
Field notes
Backcat describes a five-stage pipeline: audio ingestion, timed windows, embeddings, a graph of concepts and people, and retrieval. Its proposed answer format preserves a video and mm:ss citation, with the in-app player seeking to the cited moment instead of opening YouTube. Collections can overlap, allowing one video to support multiple research topics. The homepage also describes daily query caps and an immediate kill switch, while documentation and benchmarks are listed as forthcoming.
