Bolna is an AI voice agent platform built for India. Teams build phone agents that call and answer in 40+ languages, then deploy them through a no-code dashboard or the REST API.
About Bolna
What Is Bolna
Bolna is a voice AI platform for building agents that hold real phone conversations. Companies use it to qualify leads, run support lines, book appointments, and chase collections. You describe what the agent should do, connect the models and phone numbers you want, and it starts taking calls.
The product targets a specific gap. Indian businesses run huge volumes of calls across sales, support, and recruitment, and building a team that covers 20+ languages and accents is close to impossible. Bolna packages the speech, telephony, and orchestration layers so a small team can run those calls with AI instead.
The main thing to weigh is fit. Bolna is built India-first, with data residency options for India and the USA and deep support for Hinglish and Indian languages. Teams outside that market can still use it, but should confirm language quality and number coverage for their own region before committing.
Getting Started
- Open the platform and try a live agent without signing up, or create an account to build your own.
- Describe your use case in Agent Studio, which generates a call-ready agent you can adjust, or start from an agent template.
- Pick the speech, language, and text models you want, and connect a phone number and any external APIs the agent needs.
- Test the agent on a real call, then launch outbound campaigns or point inbound numbers at it.
- Watch calls, transcripts, and outcomes in the dashboard, or pull them through the API.

Key features
Bulk Calling at Scale
Bolna runs campaigns with thousands of simultaneous AI calls. A team that would otherwise need rows of callers triggers the whole list from the dashboard or the API, which is what makes large outreach affordable.
Custom API Triggers
During a live conversation, the agent can call your own APIs in real time. That lets it pull an account balance, check an order status, or write a result back to your system without ending the call.
Human-in-the-Loop Transfer
When a conversation gets complicated, the agent transfers the call to a human agent instantly, with context attached. Callers get a person when they need one instead of being stuck with a bot.
Model Switching Across 20+ Models
Bolna connects to more than 20 speech recognition, language, and text to speech models, and you can choose which one runs each call. A team can match the model to the job, whether that is low latency, an Indian accent, or a lower cost.
Multilingual Conversations
Agents speak 40+ languages and detect and switch language mid-call. The India-focused set covers Hinglish, Hindi, Tamil, Telugu, and Bengali with native accents, which is the hard part for most voice stacks built elsewhere.
Natural, Low-Latency Calls
Bolna agents understand interruptions and reply in under 300 milliseconds, so conversations feel closer to a phone call with a person than a scripted bot.
Workflow and Tool Integration
Bolna plugs into no-code automation tools like n8n, Make.com, and Zapier, plus telephony providers. Existing workflows can trigger a call and act on the result without custom glue code.
Data Residency and Enterprise Controls
Bolna offers India or USA data residency and on-premises deployment options, along with enterprise plans and forward-deployed support. That gives regulated teams a path to keep call data inside the region they answer to.
