Describe it once. Run forever.

Every conversation can become a reusable flow. Schedule it, share it, chain it into another. Your “investor outreach” becomes a Monday morning ritual that runs without you.

  • Recurring runs (hourly, daily, weekly, cron)
  • Approval gates for human-in-the-loop steps
  • Branching, error handling, retries
  • Shareable with your team, version-controlled
