Bolna AI Pricing vs Bolti: Which Voice Agent Costs Less?

Bolti Team·

Bolti is a voice AI platform for building production-ready conversational phone agents, starting at ₹7/min with a free 50-minute trial. If you've been searching for Bolna AI pricing and wondering how it compares to alternatives, this page breaks down what you'd actually pay — and what you get — across both platforms.

What Is Bolna AI Pricing?

Bolna AI is a voice agent builder that competes in the same space as Bolti. As of mid-2025, Bolna's public pricing is structured around usage tiers, but the details — included minutes, overage rates, and feature gating — aren't always transparent on their site. Most teams evaluating Bolna end up on a sales call before they see exact numbers.

This matters because voice agent costs compound fast. If you're running 500 outbound calls a day, even a ₹1–2/min difference adds up to ₹15,000–30,000 per month.

How Does Bolti Pricing Compare?

Bolti charges ₹7/min, pay-as-you-go, with no monthly minimums and no feature gating by tier. You get the same platform whether you're running 10 calls a day or 10,000.

Here's what's included at ₹7/min on Bolti:

  • Access to all supported STT providers (Deepgram, Fennec for Indian languages, Azure, ElevenLabs, AssemblyAI, Cartesia)
  • All supported LLMs (OpenAI GPT-4o family, Google Gemini 2, Groq Llama, DeepSeek)
  • All TTS providers (ElevenLabs, SarvamAI for Indian-language voices, Cartesia, SmallestAI)
  • BYOC telephony: bring your own Twilio, Plivo, or Exotel SIP trunk, or use Bolti-managed numbers
  • Full REST API — every dashboard action is also an API call
  • Sub-second turn-taking and real interruption handling

Note: your total per-minute cost will also include whatever your chosen STT, LLM, and TTS providers charge — Bolti's ₹7/min is the platform fee on top. This is the same model most voice agent platforms use, including Bolna.

What Does a Typical Deployment Actually Cost?

Let's make this concrete. Suppose you're running an outbound payment-reminder campaign — 200 calls/day, average call length 2.5 minutes.

Daily call volume: 200 × 2.5 min = 500 minutes
Bolti platform fee: 500 × ₹7 = ₹3,500/day
Monthly (25 working days): ~₹87,500

Add STT + LLM + TTS costs on top (typically $0.002–0.01/min depending on providers chosen). If you pick Groq Llama for the LLM and SmallestAI for TTS, you keep provider costs low. If you pick GPT-4o + ElevenLabs, you pay more — but you get better quality.

Bolti gives you per-agent provider control, so you can tune this per use case. A high-volume lead-qualification agent can run on cheaper providers; a customer-facing support agent where voice quality matters can use ElevenLabs + GPT-4o.

What Features Do You Actually Get?

Pricing comparisons only make sense alongside feature comparisons. Here's what Bolti includes that's relevant if you're evaluating Bolna:

Indian-language support

Bolti supports Hindi, Marathi, Tamil, Telugu, Bengali, Gujarati, and 80+ global languages. For Indian-language calls, Bolti integrates Fennec (STT) and SarvamAI (TTS) — both optimized for Indian accents and native prosody. Most global-first platforms, including Bolna, treat Indian languages as an afterthought.

Telephony flexibility

Bolti supports BYOC (bring your own carrier) via Twilio, Plivo, or Exotel SIP trunks, or you can use Bolti-managed numbers. If you already have an Exotel account with negotiated rates, you can keep it.

LLM and voice provider choice

Every agent on Bolti lets you independently choose STT, LLM, and TTS providers. You're not locked into one stack. This matters for cost optimization: swap Groq Llama in for a scripted outbound agent and cut LLM costs significantly versus GPT-4o.

Enterprise features

For teams that need it: on-premises deployment, PII redaction at runtime, SSO via OIDC/SAML, sub-accounts for white-labelling, and DPDP/GDPR/HIPAA-aligned contracts. These are available on Bolti; check whether Bolna offers equivalent controls before signing an enterprise deal.

Open API

Every action you can take in the Bolti dashboard — create an agent, launch a campaign, pull call logs — is also available as a REST API call. This matters if you're integrating voice agents into your CRM, helpdesk, or internal tooling.

Who Uses Bolti and for What?

Bolti is used across outbound sales, customer support, appointment booking, HR screening, payment reminders, and after-hours helpdesk. You can see real deployment examples on the Bolti use cases and case studies page.

Common setups:

  • Outbound collections: 500+ calls/day, Hindi + English, Fennec STT, Groq LLM, SarvamAI TTS
  • Inbound support: 24/7 helpdesk, English, Deepgram STT, GPT-4o, ElevenLabs TTS
  • HR screening: automated first-round calls, multi-language, structured data extraction via tool-calling
  • Appointment reminders: short outbound calls, low-cost provider stack, high volume

Each of these has a different optimal provider mix — and Bolti lets you configure them independently per agent.

Set Up Your First Voice Agent and Compare Costs Yourself

The clearest way to compare Bolna pricing against Bolti is to run a real test.
