FloodProof

During disasters, old or foreign footage goes viral with false captions. During the August 2026 Nepal floods, an Alaska glacier clip was shared as the Rasuwa GLOF. Fact-checkers cannot keep up, and "is this fake?" AI scores cannot be checked. FloodProof takes a video link or upload plus the claim, and returns an evidence report anyone can inspect: earlier copies of the footage proven frame by frame by a deterministic matcher (SIFT + RANSAC, not an AI guess), upload dates re-checked independently, Muse clues from the frames and the narration, and a check against disaster records (Copernicus EMS, GloFAS, Open-Meteo, GDELT). The verdict is one of three labels, never a fake score. On 17 already-debunked viral clips it proved an earlier copy for 10, with 0 false accusations, at about 1.4 to 1.7 cents per check. Each report includes a shareable debunk card in English, Nepali and Hindi.
