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.

Collaborative AI agents for production software engineering
A shared representation of your code, tickets, observability signals, people and deploy history that gives every agent one source of truth to reason from.
Purpose-built agents for support triage, SRE incident response, engineering root-cause work and QA validation, delegating questions to the right owner and keeping answers in one thread.
Changes fan out into parallel scenario runs that compare actual behaviour against expectations and hold the release gate until they match.
Work is split by owner automatically, with delegated questions tracked in a single workflow so nothing stalls in an inbox.
