AI made decisions.
We keep the receipts.
EU AI Act Article 12 Compliance — Open Source SDK
Cryptographic audit trails for AI agents. Comply with the EU AI Act Article 12 using an open-source SDK that integrates in minutes.
The SDK is open-source and free (MIT). Start using it today — no sign-up required.
The problem
The EU AI Act requires traceability.
Your tools weren't built for this.
Splunk gives you logs, not audit trails
Your engineering team uses observability tools for debugging. But a raw timestamp and a JSON blob is not what an EU regulator will accept as proof of compliance.
OneTrust charges €50K+ for features you don't need
Enterprise GRC platforms are built for risk assessments and vendor management — not for tracking what your AI agents decided. You're paying for a data center when all you need is a receipt.
Nobody knows what their AI actually did
The scariest sentence in AI compliance: "I don't know why it made that decision." Without cryptographic receipts, you have no proof — just logs that can be edited, deleted, or denied.
You're caught between the sword of regulation and the wall of budget.
AgentTrail is the way out.
The solution
One receipt per decision. That's it.
AgentTrail generates a cryptographic receipt for every AI agent interaction. The data stays in your infrastructure. No vendor lock-in. No data retention.
Zero data retention
Receipts stay in your S3, GCS, or local filesystem. AgentTrail never sees them. Your data, your control.
Tamper-proof by design
SHA-256 hash chain + Ed25519 signatures. Modify one receipt and the entire chain breaks. An auditor can verify it offline in seconds.
Open-source, auditable
MIT license. Fork it, audit it, extend it. No vendor lock-in. No black boxes. What you see is what your compliance depends on.
How it works
Three steps to tamper-proof compliance
Install the SDK
Add AgentTrail to your project with a single command. Works with OpenAI, Vercel AI SDK, or as a standalone wrapper.
$ npm install @aivoralabs/agenttrail
Every decision generates a signed receipt
Wrap your agent once. Each call automatically produces a cryptographic receipt with SHA-256 hash, Ed25519 signature, and full interaction metadata.
import { wrapOpenAI } from '@aivoralabs/agenttrail-openai'; const client = wrapOpenAI(openai, { agentId: 'legal-ai', complianceMode: 'strict', });
Verify the chain with one CLI command
Generate a self-contained HTML audit report. Green badge = chain intact. Red badge = tampered. Ready for your auditor.
$ npx @aivoralabs/agenttrail-cli verify audit-log.jsonl --output report.html # or if installed globally: $ audit-receipt verify audit-log.jsonl --output report.html ✓ Chain intact: 150 receipts verified ✓ Signatures valid: 150/150 → HTML report written to report.html
Example: Auditor's HTML Report
Self-contained, print-ready, zero external dependencies. Generated by the CLI.
