Sign it. Seal it.
Prove it.

NsayinoDocs turns a PDF into a legally binding, cryptographically provable document — drafted, routed, and signed without ever leaving the browser.

Paper doesn’t scale, and a scanned signature doesn’t prove anything.

Most offices still route documents the same way they did twenty years ago — and it shows.

Turnaround measured in days

Printing, courier and manual filing stretch a single approval into a week-long errand.

Nothing to verify

A scanned signature or a pasted image proves nothing about who signed, or whether the document changed afterward.

Five tools for one document

Staff bounce between converters, editors and email threads just to get one file ready to sign.

PDF toolkit

Every document tool, in one place

Fourteen document-processing functions run natively in the platform, so staff stop exporting files to third-party converters and losing track of the original.

  • Merge, split, reorder, insert and extract pages
  • Compress, watermark, and add headers or footers
  • Protect with AES-256, or unlock and flatten forms

Digital signatures

A signature that’s legally binding, not just cosmetic

Every signature applies a real PKCS#7 digital signature using RSA/SHA-256, generated from an issued certificate. That gives authentication, integrity checking and non-repudiation that validates natively in Adobe Acrobat.

  • Sequential multi-signer approval, with decline reasons
  • Automatic reminders for signers who haven’t actioned a request
  • One-click verification of every signature’s validity
Editor & forms

Draft, comment and collect data without a second app

A full document editor and form builder live inside the platform, so a document never has to leave the system to get finished.

  • Rich-text editing with track changes and version history
  • Threaded comments for internal review
  • Shareable forms that external parties fill in with no login
● Draft — Annual Compliance Report
