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.
Autonomous AI QA agents that verify your web and mobile app on every pull request
Describe a journey or rule in chat and the agent turns it into durable test cases that survive refactors and redesigns.
Every pull request gets a dynamic exploratory pass with preview environments, failure breakdowns, screenshots, console and network logs.
Agents target real browsers and native iOS and Android apps, so coverage reaches beyond the web front end.
Findings flow into Jira and Linear, and agents can be queried over MCP by other coding agents.
