Praxis - Find my Car

Praxis — Find my Car is a video agent for people who lose a car in dense street parking or residential blocks. Instead of scrubbing hours of camera footage, you ask in natural language.

Community votes recognize the build and do not affect official judging.

Project description
We built on the VAST Builders Challenge stack: neighborhood and street cameras already indexed in our team VSS archive. Search uses Cosmos Embed hybrid retrieval over segment captions; Cosmos Reason supplies the descriptions we search and summarize; YOLO detections help filter vehicle-related moments. Cursor skills drove login, search, agent Q&A, and optional re-ingest when we needed captions tuned to parked cars and curb activity. App logic runs on top of the VSS APIs so the demo is search → evidence clip → answer, not a rebuilt ingest pipeline.
