Autograph Analyzer

Upload a photo or scan of an autograph. The tool estimates how human-like the strokes appear (vs plotter/machine patterns). This is a heuristic score — not forensic authentication.

Tips for better accuracy
  • Crop tightly to the autograph (reduce background).
  • A flatbed scan is better than a phone photo.
  • Avoid shadows, glossy reflections, and strong paper texture.
  • If the signature is very faint, increase contrast before uploading.
