Team FixLens
Built at Meta Global AI Developer Hackathon · Oct 26, 2026 · Remote

FixLens is a home-repair triage app. A user uploads a photo of a home fault; SAM 3.1 segments the faulty region with a box plus pixel mask; Muse Spark writes a structured diagnosis with severity plus reason, likely cause, safety warnings first, ordered repair steps, and a parts list with quantities only and never prices, plus a repair ticket that stays DRAFT and is never sent. It uses SAM 3.1 and Muse Spark through the Meta Model API, with real API calls. All FixLens code was built October 26 to November 2, 2026, during the event window. The demo video shows the real flow on a real ceiling-crack photo: upload, SAM box plus mask on the crack, moderate diagnosis, safety warnings, checklist, parts, draft ticket, and closing card. Roadmap (not built): a future monetization extension with purchase links for parts or services, Facebook Marketplace integration, and ads alongside those links. No real tenant or landlord names or addresses are used; example property, tenant and landlord names in the demo are placeholders.
