Read any signaturethe way an examiner would.
Photograph a signature — on a book, a letter, a canvas, a concert stub — and let a trained language model draft the full dossier. Signer, period, medium, market, preservation, every stroke.
Add an optional reference sample and the report ends with a side-by-side forensic comparison on a five-step scale — from Highly Consistent to Highly Inconsistent.
Compare against a known sample.
Every other signature reader looks at one photo in isolation. Signature Identifier lets you upload a reference — another signed letter, a certified autograph, a past document — and returns a stroke-by-stroke comparison with a plain-language verdict.
- Stroke consistency — slant, baseline, pressure, letter joins.
- Idiosyncrasy match — personal flourishes unique to the signer.
- Five-step similarity verdict — easy to quote, hard to misread.

Twenty-seven structured fields per reading — nothing omitted for speed.
Optional reference photo. Five-step similarity scale. Plain-language reasoning.
