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.

Battle-test and harden AI agents before they reach production.
Build bespoke test suites that mirror your real workflows so agents are measured against your rules, not generic benchmarks.
Automatically flag fabricated answers, policy breaches and unsafe outputs before an agent goes live.
Catch broken API calls, malformed arguments and failed agent tool usage that would silently break automations.
Run agents through realistic simulated scenarios to surface weaknesses without exposing real customers or data.
