Screen recorder that captures bugs with full technical context
Record your screen or grab a screenshot from the browser extension, the iOS app, or the Mac app.
Available console logs, network requests, user events, and device details ride along with every recording.
Automatic title, summary, and reproduction steps give developers and agents a clear place to begin.
Push Jams into Linear, Jira, or Slack for triage, or into AI coding tools for investigation.
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.
