The EU AI Act is now mandatory.
Are you ready?
The EU AI Act is now in force. Can you prove how you used AI in your documents? Companies that fail to document, trace, and audit their AI processes face fines of up to €15M or 3% of global turnover. Needine automates that compliance.

See a real certificate. Verify it yourself.
No account needed. Enter a certificate ID and check its integrity, signer, approval chain and blockchain anchor in seconds.
Try the verifier →"Guaranteed document integrity, auditability, and traceability."
Reviewable by any person or organization.
Regulators, auditors, and clients want to know which model, which version, which data, who reviewed it, and who approved it — before they trust any AI-assisted decision. Needine makes all of that provable.
Your company uses AI to produce sensitive documents. Needine gives you verifiable proof of integrity, traceability, and human control.
The structure never changes. Only the data does — and that's where AI delivers maximum value.
Human input & evidence
The team uploads context, source data, and supporting documents. Every piece of evidence is attached to the record before AI is involved.
Data integrity validation
Sources are verified and the payload is canonicalized and hashed. Nothing can be silently altered after this point.
AI drafts — human decides
AI generates the draft, scores trust level, and flags anomalies. The model proposes; it never approves.
Multi-step approval chain
Reviewer → Approver → Signatory. Each action is timestamped and hashed. The full chain becomes part of the cryptographic proof.
Signed document + blockchain anchor
The approved document is issued with an Ed25519 signature, anchored on Arbitrum One via Merkle tree, and publicly verifiable without login.
Built for regulated, high-stakes document operations
Cryptographic signatures
Every document is signed with Ed25519 and includes a canonical hash. Tampering is mathematically detectable — not just logged.
Blockchain-anchored immutability
Certificates are aggregated in a Merkle tree and anchored on Arbitrum One. The on-chain record is permanent and independent of Needine.
Auditable approval workflow
Reviewer, approver, and signatory roles with delegation support. The entire approval chain is embedded inside the signed payload.
AI trust scoring
Each certificate receives a 0–100 trust score based on 8 factors: anomaly detection, spike analysis, duplicate risk, provenance depth, and more.
EU AI Act & GDPR compliance
Automatic risk classification by document type, exportable compliance reports with model registry, and GDPR legal-basis trails.
Audit Rooms
Share a scoped, read-only view with external auditors using a time-limited token. No account required. Perfect for regulatory reviews.
API & SDK integration
REST API with API key auth, TypeScript and Python SDKs, and HMAC-signed webhooks. Integrate Needine into your existing AI pipelines.
Exportable legal evidence
Download any certificate as a self-contained PDF (with QR) or a JSON bundle verifiable offline. Ready for legal proceedings and audits.
The same flow. Across every regulated industry.
Input type, AI task, reviewer profile, and document format change. The audit trail, the approval chain, and the cryptographic proof do not.

EU AI Act ready
Automatic risk classification (high / limited / minimal) per document type. Exportable compliance reports covering model registry, signatories, and blockchain coverage.
GDPR legal-basis trail
Every certificate can declare its legal basis for data processing. Exportable GDPR trail per certificate — ready for data-subject requests and DPA inquiries.
External audit access
Create a scoped Audit Room with a time-limited read-only token. Auditors access the evidence they need — without becoming platform users.
Needine is infrastructure — not just a UI
Your team doesn't need to change how AI pipelines are built. Needine plugs in as the trust and certification layer at the end of any existing workflow.
REST API + API Keys
Authenticate with long-lived API keys scoped by organization. Full Swagger docs at /api/docs. Every endpoint available to the API is available via JWT or API key.
TypeScript & Python SDKs
Drop-in SDKs for Node/TypeScript and Python (LangChain-compatible). createCertificate(), verifyCertificate(), getLineage() — three calls cover 90% of integrations.
Webhooks
Subscribe to certificate.issued, anchor.confirmed, trust.updated, and more. Payloads are HMAC-signed and retried with exponential backoff.
Needine enables companies to issue verifiable documents with evidence, approval chain, and independent anchor, ready for audit, compliance and external review.
