03 / VidWise · video research
Ask six videos. Jump to the exact second.
VidWise searches several YouTube transcripts at once and returns an answer with timestamp links back to the source.
The problem
A useful answer can be buried forty minutes into one video and contradicted in another. Scrubbing timelines does not scale once the question spans several sources.
What I built
- Research across up to six YouTube videos in one session
- Semantic retrieval with query expansion and local reranking
- Clickable citations that jump to the matching timestamp
- Subtitle uploads when transcript fetching is unavailable
- An MCP server for using the same search from an agent
What still needs testing
The app and evaluation harness exist, but the published benchmark is a cancelled partial run against an older retrieval stack. It should not support performance claims. A fresh run across all five configurations is still pending.
Current limit: transcript quality and retrieval errors can still produce weak citations. The demo is useful for exploration, not a guarantee that every answer is correct.
