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.
Prompt management, evaluation, and guardrails for production LLM apps
Build, test, and version prompts in a table-based editor that anyone comfortable with spreadsheets can use.
Add natural-language assertions, pattern matching, or custom code checks and run them over datasets to catch regressions.
Trace every request and response, inspect latency and cost, and diagnose why an LLM answered the way it did.
One-click AI Firewall blocks prompt injection, denial-of-service attempts, and information leaks with customisable content filtering and alerts.
