Credentialed human review layer for regulated AI.

Every validator submits their professional license, board certification, bar admission, or academic appointment during onboarding. We independently verify each credential against the issuing authority — state medical boards, bar associations, university faculty directories. Verification typically takes 1-2 business days. Unverified users cannot access any tasks. We re-verify credentials annually and when licenses are up for renewal.

The Kelva Score is a composite rating (0-100) that measures a validator's reliability across five dimensions: task accuracy (40%), inter-rater agreement (25%), reasoning quality (20%), consistency and volume (10%), and response time (5%). It's a portable credential — validators can share it on LinkedIn and professional profiles. For AI companies, the Kelva Score is the trust signal that replaces "we hope our annotators are good" with verifiable proof.

Two fundamental differences. First, transparency — most human feedback platforms are black boxes where you never see who reviewed your data. Kelva shows you exactly which credentialed professional evaluated your AI output, their accuracy history, and their reasoning. Second, access model — most providers require sales calls, contracts, and minimum commitments. Kelva is a self-serve API marketplace. Get an API key and start submitting tasks in minutes, no sales calls needed.

Kelva is a marketplace. Validators set their own rates based on their domain expertise and the task complexity. You see the total cost per task before submitting — validator payment plus a 20% platform fee. No subscriptions, no minimums, no lock-in. A simple preference ranking task might cost $16-20 total, while a deep expert review of a treatment protocol might be $85-100. You control the budget by choosing credential levels and task types.

Kelva supports multiple task formats: preference ranking (which AI response is better), hallucination detection (flag factual errors in AI output), accuracy rating (score across multiple dimensions), free-form correction (rewrite the AI response), multi-turn dialogue evaluation, red teaming and adversarial testing, and full expert document review. Tasks range from 5-minute quick evaluations to 45-minute deep reviews, with pricing that scales accordingly.

Kelva is designed for 2-4 hour turnaround on standard tasks. The Growth tier will offer a 4-hour SLA at launch, and Enterprise customers will be able to negotiate custom turnaround guarantees. Results stream back as individual validators complete their evaluations, so you'll see data within minutes of submission — you don't wait for the entire batch to finish.

Yes. All data is encrypted in transit and at rest. Validators operate under NDA and cannot store, screenshot, or redistribute any AI outputs they review. We are pursuing SOC 2 Type II certification and are designed to be HIPAA-compliant for medical AI customers. Enterprise tier supports dedicated validator pools where only pre-approved reviewers see their data. Full audit trails are maintained for regulatory compliance including EU AI Act requirements.

Yes — this is one of Kelva's strongest use cases. The EU AI Act requires documented human oversight for high-risk AI systems, which includes medical and legal AI. Kelva provides a full audit trail showing exactly which credentialed professional reviewed each AI output, their qualifications, their assessment, and their reasoning. This documentation is designed to satisfy the human oversight requirements that regulators will be looking for.
