Product
Enterprise AI Evidence Infrastructure
Evidentia is not a Web3 product, crypto product, generic logging tool, or legal-proof service. It is AI Proof Infrastructure for organizations that need independently verifiable records of AI decision events.
- Creates tamper-evident Proof records for AI decisions and AI-assisted workflows.
- Records event_hash, signature, timestamp, public verification metadata, and anchor state without exposing raw payload.
- Provides a public verification page and export package so reviewers can independently inspect proof integrity.
- Supports API-first integration for B2B SaaS, compliance, risk, and operations teams.
Business model
B2B SaaS / API infrastructure
- B2B SaaS / API infrastructure for organizations that need verifiable AI decision records.
- Developer access is available during Open Beta for evaluation and integration testing.

Verification boundaries
What Evidentia does and does not prove

- Evidentia does not prove that an AI decision itself was correct.
- Evidentia does not prove that submitted input was factually true.
- Evidentia does not guarantee legal admissibility, regulatory compliance, certified security, or audit approval.
- Evidentia verifies proof record integrity and consistency with recorded anchor metadata.
