ProofFlow helps people turn the procedures they know into visual checks they can review against a video. It is built for everyday tasks such as packing an order, assembling a kit, or following a workshop procedure. A user describes what should happen, and ProofFlow helps create a Proof Plan with clear, observable checks. The user reviews and approves that plan before uploading a short video. Each run keeps the exact version of the checks that was approved. The results connect each finding to video timestamps and tracked objects, so users can inspect the evidence themselves. Findings are marked as observed, not observed, or uncertain. If something is hidden or unclear, the app keeps that uncertainty visible. I wanted to make this useful without requiring people to collect a training dataset or train a custom model. The working demo includes two packing videos with saved model evidence that judges can explore directly.
