Built for the evidence economy
Start with the job your team needs to prove. The same open verification layer serves each path.
Sign at publish, see provenance checks, and add paid external-domain detections through Attribution Analytics. Build a source-linked record for licensing; AI-usage metering is an early-partner program.
See publisher workflowsVerify signed sources and mark completed AI outputs now. Early integration partners add retrieval and outcome events to measure which sources support useful RAG and search results.
