Voice and chat agents that actually do the work: they answer the phone, reply on your site, look things up and hand over to a person when it matters.
What it is
Voxylo lets a business build AI agents for phone calls and web chat without writing code. You design the conversation on a visual canvas, connect a knowledge base and your own APIs, test it in the browser, then put it live on a phone number or a website widget.
It's my own product. I designed and built all of it: the flow builder, the agent runtime, telephony, billing and the marketing site.
The flow builder
What it does
Visual flow builder
Drag and drop the conversation: messages, buttons, conditions, agents and tools.
Knowledge base
Upload PDFs and docs or crawl a website, and agents answer from it.
Phone and web chat
Bring your own SIP trunk or numbers from Twilio, Telnyx, Vonage or Plivo, or embed a chat widget.
Tools and APIs
Agents call your REST APIs and MCP servers in the middle of a conversation.
Human handoff
When it matters, the agent passes the caller to a person.
See every call
Transcripts and every tool call are logged, so you can see exactly what happened.
How it fits together
- Flow builderNext.js dashboard
- APINode.js + MongoDB
- Agent runtimeLiveKit: speech in, speech out
- Phone & web chatCalls and site visitors
- Knowledge & toolsDocs, APIs, MCP
- Flow builder connects to API
- API connects to Agent runtime (publishes flows)
- Agent runtime connects to Phone & web chat (answers)
- Agent runtime connects to Knowledge & tools
- Agents are designed as flows, not just prompts, so a business can see and control what happens on a call.
- Speech, language and voice providers are swappable per agent.
- Everything is tested in the browser before it goes near a real phone number.
