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.
Pin feedback on any live page and hand it straight to your AI coding agent
Comment on any element of any page — prototype, staging, localhost or production — so every thread is attached to the exact element it refers to.
Claude, Claude Code, Cursor, OpenAI Codex, Grok, Windsurf, Lovable and Bolt can list threads, apply fixes and reply with the commit that closed them.
Comments are classified as they are typed — bug, feedback, idea, design inspiration or page copy — and can be sorted or bulk-managed by type.
Publish Claude artifacts or design surfaces to a hosted link; external reviewers join free and their comments land back in your workspace.
