Scale with professional annotators
Annotation Marketplace
Access a vetted pool of professional annotators matched to your domain. Define demographic requirements, set quality thresholds, and pay per annotation with full cost transparency.
Key Capabilities
Annotator Matching
Specify domain expertise, language fluency, and demographic criteria. The marketplace automatically routes tasks to qualified annotators and balances workload across the pool.
Agreement Scoring
Track inter-annotator agreement in real time with Cohen kappa and Krippendorff alpha metrics. Flag low-agreement items for review and automatically re-queue them to additional annotators.
Transparent Pricing
Pay per label or per comparison with no hidden fees. Set budget caps per project, monitor spend in real time, and download itemized invoices for every annotation batch.
Quality Guarantees
Gold-standard questions, attention checks, and speed guards run on every session. Annotators who fall below quality thresholds are paused automatically and flagged for review.
