Use tool ↗About Bolna
Bolna builds voice agents that answer and place phone calls for support, sales, collections and recruiting. Its distinguishing feature is coverage of more than ten Indian languages including Hindi, Tamil and Telugu alongside English, plus the freedom to mix and match over twenty speech recognition, language and speech synthesis models rather than accept one fixed stack. There is a no-code playground for building agents and APIs for calls, agents, phone numbers, knowledge bases and batch dialling, with telephony through Twilio, Plivo or Vobiz and hooks into n8n, Make and Zapier. The company behind it is Whismurwave Inc., operating from India, backed by Y Combinator and a $6.3M seed round led by General Catalyst. The domain bolna.dev now forwards to the current site.

Pros & cons of Bolna
Bolna competes on two things Western voice-agent platforms handle badly: Indian language coverage and per-minute price. Being able to swap the recognition, language and speech models independently is genuinely useful when one vendor's accent handling fails on your callers. It is a developer product first — the playground exists, but the APIs and telephony wiring are where the work is.
Pros
- Over ten Indian languages plus English, an area most voice platforms cover poorly
- Twenty-plus interchangeable ASR, LLM and TTS models rather than a single fixed stack
- APIs for agents, calls, numbers, knowledge bases and batch dialling, plus n8n, Make and Zapier
- 6 cents a minute billed in 30-second increments, with volume rates down to about 4.5 cents
Cons
- Purely metered, so a bad prompt loop turns directly into spend
- Telephony charges from Twilio, Plivo or Vobiz are additional and not included in the quoted rate
- Pay-as-you-go requires a credit purchase of at least $10 up front
- Concurrency and support levels are tied to the Pilots or Enterprise commitments
Best for
- Teams running call operations in Hindi, Tamil, Telugu or other Indian languages
- Developers who want to choose their own ASR, LLM and TTS combination per agent
- High-volume outbound campaigns where a per-minute rate under 6 cents matters
Not for
- Non-technical buyers wanting a fully managed call centre rather than a platform
- Teams that need a fixed monthly bill rather than metered per-minute charges
Watch out: The quoted cents-per-minute covers the bundled speech and language models only; telephony and a per-minute platform fee are added on top, so model your true cost as Bolna plus carrier plus any premium voice.
