Your AI application sends a task via the REST API with structured checklist items, severity level, and evaluation criteria.
Structured human review for AI-generated content. Multi-reviewer consensus, quality scoring, and audit trails — built for teams that can't afford to ship unchecked AI.

Three steps to validated AI
Your AI application sends a task via the REST API with structured checklist items, severity level, and evaluation criteria.
Human validators independently review each item, score against criteria, and approve or reject with structured feedback.
Approved outputs are returned via webhook with full audit trail. Rejected items loop back with feedback for rework.
Built for production AI workflows
Require N independent validations before reaching a final decision. Configurable per task severity.
Weighted evaluation criteria with composite scores. Track quality trends across tasks and validators.
Rejected items loop back to the AI application with structured feedback for iterative improvement.
Inject benchmark items with known answers to continuously measure validator accuracy and reliability.
Automatic escalation when review deadlines approach. Configurable SLA windows per severity level.
SSE endpoint for live task status updates. Know the moment a validation completes or escalates.
Where AI meets accountability
Ensure AI-drafted patient summaries, discharge notes, and triage recommendations are reviewed by qualified clinicians before entering medical records.
AI-extracted contract clauses, risk flags, and compliance checks validated by legal professionals before reaching the client.
Financial models, risk assessments, and market analyses produced by AI reviewed by analysts before distribution to stakeholders.
Insert a human checkpoint in your ML pipeline. Catch hallucinations, data drift, and edge cases before they reach end users.

All data is hosted on Scaleway in the fr-par (Paris, France) region. 100% EU infrastructure. No data leaves the European Union.
Your AI app submits a task via the API. Validators are assigned based on severity and workload. Each validator independently reviews and scores the items. Once the completion strategy is satisfied (e.g., all approved, minimum score reached), the result is delivered via webhook.
Any structured output: text, code, JSON, tables, documents, and images. Each task item supports file attachments via S3-compatible storage and custom checklist criteria for evaluation.
Yes. The API includes data export and deletion endpoints. Data retention is configurable per tenant. All processing happens within the EU. We provide a DPA (Data Processing Agreement) on request.
Yes, on the Enterprise tier. We provide Docker images and Helm charts for deployment on your own infrastructure. Contact us for details.
