AI-powered document verification
built for speed, trust and accuracy.
01 — Problem
Manual document review took an average of six minutes per applicant and still missed a meaningful share of doctored or template-generated fake IDs, across dozens of formats and countries — while needing to run fast enough not to lose an impatient applicant mid-signup.
02 — Solution
A classifier identifies the document type on sight, OCR extracts every field, and a verification model checks it against the forgery patterns real fraud attempts actually use — font mismatches, tampered holograms, inconsistent microprint.
