Early Access · 3 Partners Only
For compliance, risk, and AI teams in regulated industries.

Your AI made a decision.
Can you prove it under audit?

AI regulation is coming. Audit requirements won't wait.

Regulators, auditors, and legal teams are asking. Most organizations using AI in decision workflows have no systematic answer. Evidentia is the infrastructure that changes that.

The Problem

AI is deciding.
Accountability hasn't caught up.

Regulated industries are deploying AI into real decision workflows — finance, healthcare, legal, enterprise operations. The productivity gains are real. So is the exposure.

When an auditor asks "how did your AI reach this conclusion?" — most organizations cannot answer systematically. When a legal dispute arises over an AI output, there is no chain of custody. When a regulator requests evidence of AI behavior, there is no standard format.

This is not a technology problem. It is an infrastructure gap. Evidentia closes it.

🔍

No Verifiable Trail

AI interactions cannot be reconstructed or proven for audits, disputes, or regulatory reviews.

⚖️

Legal Exposure

Without evidence infrastructure, organizations cannot defend AI-related decisions when challenged.

📋

Compliance Gaps

EU AI Act and sector regulators demand AI accountability. Most teams have no systematic answer.

How It Works

Five steps from AI activity
to permanent, verifiable proof.

01

Connect

Integrate with your AI endpoints via SDK, HTTP proxy, or webhook. Designed to fit into existing AI workflows with minimal integration overhead.

SDKWebhookAPI
02

Fingerprint

Each AI interaction is converted into a cryptographic fingerprint (SHA-256). Your raw prompts and outputs never leave your environment — only proof data is processed.

SHA-256Zero raw data transfer
03

Sign & Timestamp

The fingerprint is signed with Ed25519 and anchored with a trusted timestamp (RFC 3161-compatible) — establishing exactly when the evidence was created and proving it has not been altered.

04

Anchor

Proof data is written to an independent, publicly verifiable ledger — creating a permanent record that anyone can verify independently, at any time, without accessing your raw data.

Independent anchoringPublic verification
05

Export

Generate evidence packages in JSON-LD and human-readable PDF/HTML for audits, legal review, or regulatory disclosure. Cryptographically self-contained — no dependency on Evidentia to verify.

Architecture

Privacy-first.
Independently verifiable.

We process only cryptographic proof data. Your raw AI content never enters our systems — by architectural design, not policy.
