Build your own
Choose a template. Write your prompt. Pick a voice. Start talking — live, in your browser. No account. No setup. Just your agent, ready in minutes.
From zero to live call
Every choice you make shapes the agent in real time. No config files. No deployments.
Pick a template
Start from a proven base — Lead Qualifier, Support Agent, Appointment Setter, Sales Assistant, or Onboarding Guide. Each comes with a production-grade system prompt you can customize.
Make it yours
Add your business name, agent name, and tone. Every field injects directly into the prompt in real time. Or edit the full system prompt manually — the agent updates as you type.
Upload knowledge (optional)
Drop in a PDF, TXT, or DOCX and the agent will answer questions from it. Product sheets, FAQs, pricing guides — whatever your agent needs to know.

Real AI. Real infrastructure.
This demo runs on the same architecture Calypto deploys for clients. What you're configuring here is a real voice agent — built on the infrastructure that powers enterprise teams at scale.
A live agent, on the spot
A real, working agent spins up the moment you land. Personal to you, isolated to your session, and gone the second you leave.
Real-time prompt sync
Every edit reaches the agent in under a second. Hit call and you're talking to the exact version you just wrote — no rebuild, no redeploy.
Bring your own knowledge
Upload a PDF and the agent learns it on the fly. Answers stay grounded in your content — your products, your policies, your voice.
See every word, live
Both sides of the call transcribed in real time as you speak. Easy to review, easy to share, easy to learn from.
A brain you can swap
