The chat that does.
Not another chatbot. A true AI coworker: 50+ models, 1000+ app integrations, your private knowledge, and multi-step workflows — all orchestrated from one conversation.
Pick the model. Or let us route.
Every prompt gets the right brain for the job. Switch in one click, compare side-by-side, or trust our router to choose the best model per task — cost, latency, or quality first.
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
