India loses lakhs of crores to document fraud every year. Fake job letters, forged court notices, fabricated bank PDFs — they arrive on WhatsApp at midnight, look official, and panic you into paying. SeerSign gives you forensic-grade signals in seconds, without sending your file anywhere.

A fake court notice lands at 11 PM. Stamp, seal, case number — your name on it. Enterprise forensics costs lakhs; ordinary people had nothing free and local.

SeerSign turns panic into evidence: font mismatches, ELA hotspots, checksum failures — explained in plain language.

Built by Seerror for India: Aadhaar/PAN/GSTIN math, Indian letterhead patterns, UPI receipts, WhatsApp-forward tells, and a growing fake-template database — all running offline in Chromium.
