How AI Field Detection Works

1

Visual Scanning

The AI scans the document visually — identifying signature lines, underscores, boxes, and typical field layouts that appear across thousands of contract types.

2

Semantic Understanding

It reads the text surrounding each potential field. "Sign here", "Authorized Signatory:", "Effective Date:", and similar language confirm field type and purpose.

3

Field Placement & Assignment

Fields are placed at pixel-perfect positions with the correct type and assigned to the right signer role. You review, adjust if needed, and send.

Frequently Asked Questions

Does it work on scanned PDFs?
Yes. Zignature runs OCR on scanned documents before field detection, so legacy contracts, scanned paper forms, and image-based PDFs all work. The accuracy is slightly lower on very poor-quality scans, but excellent on standard office scanner output.
Can I correct misplaced fields?
Absolutely. All detected fields open in the visual template builder where you can drag, resize, delete, or change the type of any field. You can also add fields the AI missed. Think of detection as a head start — you have full control over the final placement.
Does it assign fields to the right signer?
Yes. For multi-party documents, the AI identifies which signature block belongs to which party (Client vs Provider, Buyer vs Seller, Employee vs Employer) and assigns fields to the correct signer role accordingly.
What file formats are supported?
PDF (native and scanned), Microsoft Word (.docx, .doc), and rich text formats. Documents up to 200 pages are supported. For very large documents, field detection is applied page-by-page with full accuracy maintained throughout.
