LeaseLens is a zero-hallucination legal auditor and deposit-evidence shield for international students and expats who must sign leases in languages they cannot read. Drop in a lease from Germany, the UK, France, New York or Japan: Muse Spark Open flags risky clauses, but deterministic Python verifies every quote character-for-character against the raw document and every citation against a statutory registry before anything is shown — then drafts a bilingual objection letter. On move-in day, SAM 3.1 segments damage from photos or a narrated walkthrough video, guided by Muse Voice transcription, and seals the evidence into a SHA-256 handover protocol. At move-out, a similarity-registered IoU engine proves pre-existing damage despite camera shift. One click compiles everything into a tamper-evident Master Case Dossier PDF. Built for the Meta Global AI Developer Hackathon with Meta models end to end, a local CreditShield budget ledger, and 197 automated tests guarding every claim it makes.
