Nexart

Your AI made a decision. Can you prove it?

About Nexart

NexArt provides organizations with cryptographically signed, tamper-evident records of AI system executions, supporting audit, compliance, and dispute resolution needs. The platform generates Certified Execution Records that capture inputs, outputs, parameters, and model identifiers, allowing third parties to independently verify what an AI system actually executed. Sensitive data can be kept private through cryptographic commitments, and verification does not require a NexArt account. NexArt is suitable for regulated sectors such as finance, insurance, and healthcare. The service offers a free tier for up to 100 certified runs per month, with paid plans for higher usage and advanced features.
