Bolna

What is Bolna?

Bolna is a platform for building conversational voice AI agents that handle inbound and outbound phone calls. It is designed for developers and no-code users, with a visual playground, prebuilt templates, APIs, and configurable speech-to-text, language-model, text-to-speech, and telephony providers. Its current positioning emphasizes Indian languages and accents, including Hinglish, Hindi, Tamil, and Telugu, alongside other supported languages.

Agents can answer questions, qualify leads, book appointments, screen candidates, confirm orders, run surveys, and call external APIs during a conversation. They can transfer a call to a person when required and send post-call summaries, extracted fields, or webhooks into connected systems. Bolna supports bulk campaigns, concurrent calls, CRM and workflow integrations, and bring-your-own-provider credentials.

2. Configure the prompt, knowledge, voice, language, transcriber, model, and telephony provider.
3. Add tools, CRM or scheduling integrations, extraction fields, and transfer rules.
4. Test the agent in the playground or receive a test call.
5. Connect a phone number and deploy it for inbound calls, outbound campaigns, or API-triggered calls.
