Unlimited e-signatures. Radically private.
Drop a PDF and CyberSygn finds every signature line for you. Send it, get it signed, keep the tamper-evident audit trail. Unlimited documents for the price of a single seat elsewhere, and your files never leave your browser until you choose to send.
In their words.

A fair comparison.
DocuSign built the category. These are the plain differences people weigh when they switch. Facts only, so you can decide for yourself.
Unlimited, not metered
Send as many documents as you need on a flat plan. Incumbent plans commonly cap envelopes per user and charge once you pass the limit.
Fields found for you
CyberSygn reads the PDF and highlights every signature line, initial, date, and checkbox. The usual flow is dragging each field onto the page by hand.
One flat price
Solo is a single low monthly price for unlimited documents. Studio adds a shared three-seat workspace. No per-seat math to get to unlimited sending.
Files stay in your browser
Detection runs on your device. Your document does not leave the page until you choose to send it, a claim a server-side signer cannot make.

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
Court-ready evidence: every signing event, IP, timestamp, and a SHA-256 fingerprint.
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.

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. Here is the plain deal: free documents may be used, without any personal content, to improve our field detection. Paid documents never are. Signed PDFs are stored long enough for the signing flow to complete, then expire.
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.

We ran field detection on all 499 real contracts in our test corpus and found signature fields in 499 of 499, plus 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.
Every plan is unlimited and starts with 3 free documents, no card required. Solo is $12 per month for the essentials. Pro is $19 per month and adds the AI co-pilot that drafts and reads your contracts, plus bulk send and priority support. Studio is $29 per month for a 3-seat team. Business is $79 per month for 10 seats with white-label, single sign-on, and the API. Annual billing saves two months. Two early-adopter options remain while spots last: 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.
