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.
Free templates.
Download the starting point, edit the specifics, sign in CyberSygn. Every template in the library has been validated against the detector — drop it in and every field appears automatically.
The field-placement tax.
Enter how many documents you send per month and what your time is worth. We'll show the math on what manual field placement is costing you.
SHA-256 audit cert
Every signed PDF gets a fingerprinted certificate that holds up in court.
Browser-local
Detection runs in your browser. Bytes never leave the page until you choose to send.
ESIGN + UETA
Same federal-level legal weight as DocuSign, HelloSign, and Adobe Sign.
100% regression
Detection accuracy passes 499 of 499 real-world contracts plus 120 synthetic tests across 12 categories.
Built on Cloudflare
Edge-deployed. Low latency everywhere. The same network Google uses.
Origin members.
— of 100 Origin spots claimed. When the cap fills, the rate disappears. Forever.
Before you decide.
Yes. From your dashboard, one click, no email required. You keep access through the end of the billing period. Origin members lose the $9-for-life lock if they cancel, but every other tier is fully reversible.
Yes. CyberSygn is ESIGN Act (United States) and UETA-compliant. The audit certificate captures every signing event, IP address, timestamp, and the SHA-256 fingerprint of the original document. Same legal weight as DocuSign or HelloSign in any U.S. jurisdiction.
No, ever. Free-tier signups consent to anonymous, content-free field-position data being added to our detection-improvement corpus. Paid tiers opt out by default. Signed PDFs are stored long enough for the signing flow to complete, then expire. Read the full privacy policy.
No. Signers click a unique magic link and sign in their browser. No signup, no password, no app to install. The most-hated part of DocuSign-style flows is the part we removed.
Cancel anytime from your dashboard in one click — the next month does not bill, and you keep access through the end of the current period. Try the free Demo first (3 documents, no credit card) to confirm the detection works on your contracts before subscribing.
Pricing.
Most e-signature tools meter your documents and charge for every seat. CyberSygn does not. Pick a plan, send as many contracts as you want, cancel in one click. Start free, no card.
The typical solo e-signature plan runs $20 to $25 a month and still caps how many documents you can send. CyberSygn Solo is $12 a month for unlimited.

100% on our regression set of 499 real-world contracts and 120 synthetic test PDFs across 12 detection categories. 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.
Demo is free for 3 documents lifetime, no card required. Solo is $12 per month for unlimited documents. Studio is $29 per month for a 3-seat team with shared workspace and member roles. Two early-adopter options exist while founding spots remain: Origin at $9 per month locked for the life of your account (first 100 customers) and Lifetime at $299 one-time (first 50 customers).
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.
Origin members.
One hundred Origin spots. Once they fill, the rate goes up and never comes back down. Origin members get the first production builds, a direct line to the founder, a vote on what we build next, and a permanent place on the Origin wall.
