Design the conversation.
Not the code.
Drag nodes onto a canvas, write each step's prompt in plain English, and watch every branch play out in simulation before it ever answers a real call.
Everything you need to script a conversation
One canvas for the whole call: from the first hello to the branch that books, transfers or answers on its own.
Visual flow builder
Drag nodes onto a canvas and connect them to shape the conversation. No code, no YAML files to maintain.
Prompts & knowledge bases
Write plain-English instructions per step, backed by knowledge bases built from documents or a website crawl.
120 languages
Switch the agent's spoken language per flow, or let it detect and respond in the caller's own language.
Voice cloning
Clone a voice from a short sample so every call sounds consistent with how your team already speaks.
Simulation testing
Run test conversations against a draft flow and see exactly how it responds before a real caller ever does.
Versioned, instant changes
Every edit is versioned so you can compare or roll back. Publish and the new flow goes live immediately.
1,080 templates
Multilingual Flow and prompt templates for reception, appointment intake, support, leads and callbacks.
Force tool call
Mark a tool node as required. The agent books or checks availability instead of skipping the step.
Squad view
See every hand-off route between linked assistants as one graph. Variables carry across hand-offs.
Build once, branch anywhere.
One branch node reads the caller's answer and sends them down a different path: booking, a transfer, a knowledge-base answer, or a follow-up if nothing matches.
- Match on intent, keywords or a knowledge-base lookup
- Nest branches inside branches, as deep as you need
- Add a fallback path for anything unexpected
- Check before saving flags a missing tool or a long greeting
- Tidy up flow and Center flow keep big graphs readable
Sound like your brand, in 120 languages.
Clone a voice from a short sample so your agent sounds like your team. Pick from 120 languages and let it switch between the ones you allow.
- Clone a custom voice right from the voice library
- Assign a language per agent, or switch automatically per call
- Realtime on models like Gemini 3.8 Live, with Full Duplex (Beta)
- Recognition glossary for names, products and specialist terms
- Preview any voice and language before you publish
No add-ons, no hidden tiers
Every agent you build gets the full toolkit from day one.
Questions about the agent builder
No. The agent builder is fully visual: drag nodes onto the canvas, connect them, and write each node's instructions in plain English. Branches, conditions and fallback paths are built the same way, entirely by clicking and typing.
Build your first flow this afternoon
Start from one of 1,080 templates or a blank canvas, wire up a branch or two, and hear it work before you publish.
