What is osmTalk?
osmTalk lets you build AI voice agents that answer your phone, talk to website visitors, and reply on WhatsApp.
osmTalk is a tool that builds AI voice assistants for you. Think of it like hiring a robot receptionist who can:
- Answer your phone calls 24/7
- Talk to people on your website (chat or voice)
- Reply to WhatsApp messages
- Make outbound calls (sales follow-ups, reminders, surveys)
You don't need to write code. You write a few sentences telling the AI who it is and what to do — that's it.
A 30-second example
Imagine you run a dental clinic. You want a bot that picks up after-hours calls and books appointments. With osmTalk you'd:
- Create an agent named "Dr. Aisha's Reception"
- Write a short instruction: "You are the front desk at Dr. Aisha's Dental Clinic. Greet callers, ask why they're calling, and book an appointment if they want one."
- Buy a phone number (₹250/month) and link it to your agent
- People call that number → your AI receptionist answers, talks naturally, books the slot
Total setup time: about 10 minutes.
What you get
| AI Agents | Voice + chat assistants you configure in a web dashboard. No code. |
| Phone Numbers | Buy Indian numbers from inside the app. Calls go to your agent. |
| Web Widget | Embed a "Talk to us" button on any website. |
| Connect a WhatsApp Business number; the same agent replies there. | |
| Call History | Every call recorded, transcribed, summarized. |
| Outbound Campaigns | Upload a list of phone numbers; your agent calls each one. |
| Pay-as-you-go | Top up credits. Every call's exact cost shown. No subscriptions. |
| Shared with osmAPI | Same account, same credits work on both products. |
Who is osmTalk for?
- Small businesses that miss phone calls when they're busy
- Sales teams doing cold-call outreach
- Customer-support teams that want a 24/7 first line
- Anyone who needs to call/text many people in many languages
If you can describe what you want a human assistant to do, you can describe it to osmTalk.
What it costs (in plain English)
You pay only for what you use. Three things cost money:
- The phone number (if you buy one) — about ₹250/month
- The conversation — typically ₹2-5 per minute of voice call (varies by which AI brain you pick)
- Storage — only if you keep recordings for over 90 days
There's no monthly subscription. You buy credits, you use them, you top up when low. See Pricing for the exact numbers.

osmTalk + osmAPI
osmTalk handles voice and conversations. Its sister product osmAPI is for developers who want to call AI models directly (like OpenAI, but bundled).
You sign up once and the same credits work on both. If you only need voice agents, you only need osmTalk.
