SiteSight is an AI site-progress auditor for small construction contractors. Today, progress on Indian sites is tracked through WhatsApp photos and Excel BOQs, so every running bill is argued line by line, and existing progress tools need 360° cameras and BIM models that a G+2 residential job doesn't have.

SiteSight starts from the architect's drawings: Muse Spark reads the structural sheets and proposes the bill of quantities, with every number traced to its page (on a real drawing set it found 12 columns and 10 footings, matching the schedules). On site, the engineer just takes phone photos and adds a voice note. SAM 3.1 segments columns and brickwork; Muse Spark verifies every detection and rejects what isn't real (rebar cages, scaffolding, tarps, neighbouring buildings), measures, and assigns construction stages (shuttering → reinforcement → concreting). When it can't see enough, it asks for a specific photo instead of guessing. Work that is only inferred is kept out of the bill until a photo proves it. The engineer reviews, and SiteSight produces a bill-ready PDF with evidence, at roughly $0.15–0.20 of AI per site visit.
