02 · Workflow Studio
Design the conversation like a system, not a script.
An infinite canvas for the whole call flow. Branch on intent, call your APIs as tools mid-conversation, set compliance guardrails per node, version everything and revert in one click.
- Visual branching on intent + entities
- Your endpoints as tools, with retries
- Versioned, reviewable, revertible
03 · Call operations
The operations room is built in.
Live monitoring across every region: queue depth, sentiment, interruption rates. Whisper to the agent, barge in, or take over with the full transcript already in front of you.
- Live listen, whisper, barge-in, takeover
- Per-agent and per-flow analytics
- Full transcripts with retention rules
