STELR cryptographically signs AI-generated text and agent actions on AWS Bedrock models, so origin and integrity are verifiable by anyone, not just your own logs.
Was this AI-generated. Which model made it. Was it modified after the fact. Can it hold up in an audit, months later. Today, almost nothing answers that.
“The signature that makes AI content
and agent actions provable —
to someone who wasn't in the room.”
The core trust platform. Cryptographic identity for every AI-generated artifact.
Verification APIs that confirm origin, integrity, and authorship on demand.
An immutable evidence and chain-of-custody record, queryable forever.
Compliance and governance enforcement, mapped to the regulation already arriving.
Every output is cryptographically signed at creation through STELR Provenance.
Confirm origin and integrity anytime through the STELR Verify API.
Pull audit-ready evidence from the STELR Trust Graph, months or years later.

-H "x-api-key: <your-api-key>" \
-H "Content-Type: application/json" \
-d '{"content":"Your content here","model":"your-model-id"}'
# Verify it with STELR Verify

STELR embeds audit-ready provenance and authenticity signals directly into your AI workflows.
STELR is the trust and provenance layer for enterprise AI. It cryptographically signs AI-generated content at creation, and lets you verify its origin and integrity at any point afterward.
Provenance signs content at creation. Verify confirms origin and integrity on demand. Trust Graph stores the resulting evidence as an immutable, queryable record. Policy maps all of it to the compliance frameworks you already answer to.
Signing runs on AWS KMS with asymmetric keys. The architecture is multi-tenant and API-first from the ground up, with a growing set of enterprise controls as we onboard design partners.
