Proofwalk turns a narrated walkthrough video of a space into a structured catalog: every item gets a photo, a name, details, a count and an estimated value, grouped by room. Fewer than half of homeowners have a list of what they own (Triple-I, 2023), and after a fire or theft they have to rebuild it from memory. Proofwalk makes that list from a two-minute video. It isn’t tied to one use case: templates cover home insurance inventories, rental move-in/out condition reports, damage claims, stock counts, equipment audits and things to sell, and anyone can write their own. It’s a native Android app (plus a web app and a CLI). You bring your own API key, it estimates the cost and enforces a hard spending limit before anything is sent, and there’s no server or telemetry. While it runs, you watch items appear and lock into place; repeats seen several times fold into one line (“× 6 chairs”); and every merge can be split back. On a real 82-second home video it produced 53 lines covering 64 things, for $0.38. All Proofwalk code was written during the hackathon (commits Nov 3–4)
