Bolna
A platform for building, testing and running inbound and outbound phone-call voice agents, aimed at India with support for Hindi, Hinglish, Tamil, Telugu and other Indian languages.
About Bolna
Businesses that want AI agents to handle reminders, support or lead-qualification calls in Indian languages usually have to wire speech recognition, an LLM, speech synthesis and telephony together themselves.
Who it’s for
- Indian businesses automating reminder, collection, support or lead-qualification calls
- Developers who want a no-code dashboard plus APIs, and an MIT-licensed open-source framework on GitHub
When to consider it
Consider Bolna when you need phone-call voice agents that speak Indian languages, with bulk calling campaigns, transfers to a human agent and your choice of speech and language models.
Tradeoffs & limitations
- Usage-based pricing starts at $0.06 per minute on pay-as-you-go, with telephony and a platform fee added per minute; new accounts get $5 in free credits, and calls stop when credits run out.
- The one-time Pilot plan ($300 for 6,500 minutes or $500 for 12,000 minutes) caps concurrency at 25 calls; larger volumes need an Enterprise plan through sales.
