NexArt is an AI evidence layer that turns any AI execution into a Certified Execution Record: a portable, cryptographically sealed, and independently verifiable proof of what was executed, on which inputs, by which system. It is designed for engineers, compliance teams, and regulated industries that need to answer auditors, regulators, customers, or courts with defensible evidence—before the question is asked. With a lightweight SDK, you can record inputs, parameters, outputs, and context at runtime, then certify the record through an attestation node. Third parties can verify the record's integrity without needing an account or access to your internal systems. NexArt supports confidential execution via cryptographic commitments, keeping sensitive data private while still proving the execution. It complements observability tools, providing portable proof rather than just operational insight. Use cases include AI agent actions, customer-facing decisions, approval workflows, incident reviews, and audit assurance. NexArt aligns with frameworks like the EU AI Act, ISO/IEC 42001, SOC 2, and NIST AI RMF, but does not itself make a system compliant.
