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.
