The problem
The day it gets challenged
An algorithmic decision is disputed. A regulator opens an inquiry. Your logs cannot prove what the model saw, when it ran, or what it returned. Your word is not evidence.
AI Act compliance · Article 12 evidence
CarveTrace seals every AI decision into a tamper-evident evidence bundle that any auditor, regulator, or counterparty can verify themselves — without trusting you, and without your data ever leaving your infrastructure.
The problem
An algorithmic decision is disputed. A regulator opens an inquiry. Your logs cannot prove what the model saw, when it ran, or what it returned. Your word is not evidence.
The proof
CarveTrace captures every event your AI system emits, seals it into a cryptographic chain, and timestamps it through an independent RFC 3161 timestamping authority. The result is an evidence bundle that opens in an independent verifier — running in any browser.
The control
CarveTrace runs in your infrastructure. We do not host your data. We do not see your logs. We do not gate your verifier behind our infrastructure — it runs in your browser, on hardware you control, even offline. The cryptography is the trust — not us.
