Simple pricing.
Pay only for results.
One proof engine, five storefronts. The flagship — chargeback defense — has no monthly fee: you pay 15% only when we win.
Chargeback defense
We gather the evidence, build the defense package, and submit it. You pay only when we win the dispute back.
Reflex
Done-for-you dispute defense
No monthly fee. Cryptographic evidence captured before the dispute, packaged to the FRE 902(13)/(14) self-authenticating standard, and submitted automatically. Half the rate of Stripe Smart Disputes (30%) and Chargeflow (25%+).
- ✓ Evidence package + legal framework per dispute
- ✓ Stripe live; Shopify, PayPal, Square, WooCommerce in beta
- ✓ No win, no fee — ever
The same pay-on-win model covers AI-agent purchases and returns & warranty disputes.
Done-for-you services
For when you need hands, not software. Same honest rule on every one: we promise the work and the deadline, never the bank's decision.

The CertNode API
The same engine, as an API: sign critical events — an AI output, an agent action, a document — and verify them anywhere, without trusting the original system. Sign up, get a key, pay by usage.

Enterprise annual prepay: contact sales
Firsthand: prove you made it
Seal verifiable checkpoints of your work as you write. When someone says an AI wrote it, you show the record instead of arguing. One document free forever; $5 a month for all the documents you need. Your words never leave your browser.
Facing a hearing or a client dispute? A one-time Evidence Packet ($19) turns your record into a formatted PDF dossier for the reviewer. Verifying is always free.
Litigation-evidence casts
For active disputes headed to court: a signed, independently timestamped, Bitcoin-anchored evidence package built to the FRE 902(13)/(14) self-authenticating standard. Priced per case — we package it, your lawyer uses it.
Insurance bad-faith evidence
For plaintiff-side attorneys: a self-authenticating record of the claim timeline an insurer cannot wave away.
Proof of creation
For photographers in infringement litigation: proof of priority your lawyer can attach without a foundation witness.
