We don't hide how the engine works. We show you the byte-for-byte determination.
Resonance Labs is currently one-of-one. It's the only publicly available product that combines:
This final piece closes the loop on true auditable, defensible tracing.
The complete structured parse of your contract, every section, definition, party with aliases, and exact character ranges (sourceSpans). Full JSON output included. No summaries. No guessing. You see exactly what the engine saw.
Every finding is pinned to the precise sentence with red underlines and character offsets. Click any flag and jump straight to the triggering text.
A permanent SHA-256 hash of your input plus the complete result, plus run_id, engine version, timestamp, and provenance data. Re-run the same contract anytime, the hash will match.
See exactly how the engine moved from raw detection to final score. Pentagon dimensions (Structural Integrity, Obligation Balance, Liability Exposure, Economic Integrity, Temporal Integrity) plus Vendor vs Customer power balance, all visible and adjustable.
Every receipt's fingerprint is automatically published to a public blockchain. Anyone can independently verify that the exact analysis happened at the exact time and has never been altered. No trust required.
No black box. No hallucinations. No model drift. No “trust us.”
Just deterministic rules, full transparency, and mathematical proof.
The only contract verification engine that opens the hood and shows you the engine.
Upload any contract. Open the Raw Engine Diagnostic and Receipt tabs. You will see exactly what we saw.
Not trying to be better at drafting.
We're the last tool you can defend before you sign.
We are the only verification layer that turns every contract you touch into something you can actually defend, in court, to a regulator, or to your malpractice carrier.
Run every vendor template, every client-facing agreement, and every high-stakes NDA through Resonance Labs before you sign or deliver it.
You still use Harvey, Spellbook, or Ironclad for speed and redlines. You now use Resonance Labs for something no other product on the planet can deliver.
The same contract will always produce the exact same result, today, next year, or in discovery. Every finding is character-anchored. Every analysis produces a cryptographic receipt. Every receipt is anchored to an immutable public blockchain ledger.
No other tool on the market can say this. Because no other tool actually does it.
This is the last tool you review before you sign, and the first one that can actually be defended in court.
