AI observability platform for monitoring, explaining, and debugging production ML models
Configure performance, data quality, and drift monitors across unlimited models and model versions, with instant alerts whenever a violation is detected.
Zoom into a flagged violation and follow a guided roadmap to locate the underlying cause, moving from a symptom to a diagnosis without manual debugging.
Build fully customizable dashboards that combine monitoring and RCA insights so teams can plan the next model version with evidence.
Understand and communicate model decisions with explainability features designed for both technical teams and business stakeholders.
High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
