How it works.
Upload a PDF. CyberSygn finds the fields. Pick in-person signing on the spot, or send private links to remote signers. You get the signed PDF and a tamper-evident audit certificate the moment the last signer completes.
Any PDF works. Or photograph paper documents with your camera and we'll compose them into a PDF locally. Detection then runs in your browser and highlights every field.
Pass the iPad around if your signers are present. Or route a private link to each remote signer. No accounts, no passwords, no setup on their end.
You get the flattened PDF plus a tamper-evident audit certificate with every event, IP, and a SHA-256 fingerprint, the moment the last signer completes.

100% on our regression set of 37 real-world contracts and 10 synthetic test PDFs. The detector walks the PDF operators and matches labeled patterns including Signature:, /s/, (Initial), Date:, X______, and [ ]. Word documents are converted to PDF in the browser before detection.
No. Signers click a unique magic link and sign in the browser. No signup, no password, no app to install.
Yes. CyberSygn replaces DocuSign, Dropbox Sign, and SignWell for the case where you do not want to drag and drop signature fields onto every document. The detection step is what is different. Every other capability (multi-signer routing, magic links, audit trail, signed PDF download) is parity with the competition.
Detection runs in your browser. The PDF never leaves your device during the detection step. When you invite remote signers, the original PDF is stored in Cloudflare KV with a 30-day TTL, encrypted at rest, and auto-deleted after 30 days unless you download it.
It documents the audit trail (every event timestamp, IP, user agent, and a SHA-256 fingerprint of the original PDF). Legal weight depends on jurisdiction. We are not lawyers. The certificate is evidence, not a guarantee.
Free for 3 documents per month. Solo is $12 per month for unlimited documents. Founding is $9 per month locked for life, first 100 customers only. Team is $29 per month for 3 seats.
Yes. Word files are converted to PDF in your browser before detection runs, so the entire pipeline post-upload is PDF-native.
Yes. Manage your subscription from the dashboard. Cancellation takes effect at the end of the current billing period. No phone call required.
