Updated
From sign-up to your first AI call in about 5 minutes
- Sign up with your mobile number (1 min). OTP login, no credit card. Verify your GSTIN to get ₹150 free credit (₹50 without), enough for up to 200 calls.
- Create an agent from a template (2 min). Pick a use case, then edit the greeting, script, voice and language (10 Indian languages plus Hinglish).
- Call your own phone (1 min). Place a test call from the agent page and hear the agent respond, typically in 450–600 ms.
- Upload a list and launch (1 min). Upload an Excel or CSV file, map the columns, set retries and start the campaign.
No code is needed. Developers can do the same through the REST API or by pasting a prompt into an AI coding tool.
