Welcome to Bolti

Bolti is a voice AI platform for building conversational phone agents. Pick a persona, write a goal, choose a voice — Bolti gives you a real agent you can call, embed in your product, or wire into your telephony stack.

If you've ever tried to glue together a speech-to-text engine, an LLM, a text-to-speech engine, and a SIP trunk yourself, you know how much yak-shaving stands between an idea and a working agent. Bolti collapses that into a single dashboard, a single API, and a runtime that's tuned for telephony out of the box.

What you can build​

Bolti is general-purpose, but here's what teams typically build first:

  • Customer support agents that answer questions, look up account data, and transfer to a human when needed
  • Outbound sales agents that qualify leads and book demos
  • Appointment confirmation and reminder agents for clinics, salons, and service businesses
  • Lead-capture and IVR replacements that handle inbound calls 24/7
  • Internal voice tools — for example, a phone-based way to query your own systems
  • Multilingual agents for India and global markets, including Hindi, Indic languages, and 80+ others

If it's a phone conversation that follows a goal and might need to take action mid-call, you can build it on Bolti.

How Bolti is different​

Bolti is built for production phone calls, not just conversational demos. That shapes the platform in a few specific ways:

  • Real telephony, day one. Buy numbers from Bolti, bring your Twilio/Plivo/Exotel account, or register your own SIP trunk. Inbound and outbound work the same way.
  • Realtime stack tuned for voice. Sub-second turn-taking, telephony noise cancellation, interruption handling — all the things that make an agent feel like a person on the line.
  • Multilingual, with a focus on India. First-class Hindi, Indic-language, and Indian-English support across STT/TTS providers; 140-series compliance built in for India.
  • Workspace model that scales to teams. Organizations, workspaces, role-based membership, sub-accounts for client work — designed for agencies and platform teams, not just solo developers.
  • MCP-native. Drive Bolti from Cursor, Claude Desktop, or any MCP client. Manage agents, place calls, and inspect logs from inside your editor.
  • Open API + open dashboards. Everything you can do in the dashboard, you can do via the REST API. The dashboard is the reference implementation, not the only path.

Three ways to use Bolti​

You can pick whichever entry point fits how you work:

1. The dashboard (no code)​

Go to app.bolti.co.in, sign up, and use the agent creation wizard. You'll have a working agent in under five minutes — no API keys, no provider setup, no code. This is the right starting point for almost everyone.

→ Quick Start

2. The REST API​

Every dashboard action is backed by an HTTP endpoint. Create agents, place calls, manage phone numbers, query call logs, and run batch campaigns from any language that speaks JSON.

→ API Reference

3. The Bolti MCP server​

Connect Bolti to your AI tools (Cursor, Claude Desktop, anything MCP-compatible). Build, debug, and operate voice agents with the same assistant you already code with.
