Bolti Pricing Explained: A Transparent Cost Breakdown

Bolti is a voice AI platform for building production-ready conversational phone agents — and its pricing starts at ₹7/min with a free 50-minute trial, no upfront commitment. If you're evaluating voice AI costs before signing anything, this page breaks down exactly what you pay for and why.

What Does Bolti Pricing Actually Cost?

Bolti charges ₹7 per minute on a pay-as-you-go basis. There are no monthly seat fees or platform subscriptions required to get started. You pay for minutes used — that's it at the base level.

Here's what that looks like in practice:

• 1,000 minutes/month → ₹7,000
• 10,000 minutes/month → ₹70,000
• 1 lakh minutes/month → ₹7,00,000

For a team running outbound sales calls 8 hours a day with 5 concurrent agents, that's roughly 12,000 minutes/month — around ₹84,000. Compare that to hiring even one full-time telecaller in a metro city.

The free trial gives you 50 minutes to test with a real agent on real calls — not a sandbox demo. That's enough to run a complete outbound sequence or validate an inbound support flow before spending a rupee.

See the full Bolti pricing page for current rates and any volume tiers.

What's Included in the ₹7/Min Rate?

The ₹7/min rate covers Bolti's platform runtime — the orchestration layer that connects your speech-to-text (STT), large language model (LLM), text-to-speech (TTS), and telephony providers into a single working agent.

What that runtime does on every call:

• Sub-second turn-taking so the agent responds like a human, not a bot
• Telephony-grade noise cancellation
• Real interruption handling (the agent stops talking when the caller cuts in)
• Call recording, transcripts with speaker labels, and metadata storage
• India-resident data by default (Bolti's managed cloud runs on E2E Networks infrastructure in India)

This is not a demo environment. It's the same stack used in production deployments.

What Are the Additional Provider Costs?

Every voice call on Bolti runs through four provider layers: STT, LLM, TTS, and telephony. Each of these has its own cost, billed by the respective provider directly or passed through depending on your setup.

STT (Speech-to-Text)

Supported providers include Deepgram, AssemblyAI, Cartesia, ElevenLabs, Azure, and Fennec (optimised for Indian languages like Hindi, Tamil, and Telugu). Costs vary by provider and model — Deepgram is the default for English; Fennec is recommended for Indian-language calls.

LLM (Large Language Model)

Bolti supports OpenAI (GPT-4o family), Google Gemini (2 Flash and Pro), and Groq (Llama-family). Token costs depend on which model you choose. Groq-served Llama models tend to be the most cost-efficient; GPT-4o offers stronger reasoning for complex flows.

TTS (Text-to-Speech)

Provider options include ElevenLabs, Azure, and others visible in the agent's Speech tab. Cost is typically per character synthesised.

Telephony

You can bring your own SIP trunk — Twilio, Plivo, or Exotel — or use Bolti-provided numbers. BYOC (bring your own carrier) lets you keep your existing telephony contracts and rates. Bolti numbers are available if you don't have a carrier relationship.

The practical implication: your all-in cost per minute will be higher than ₹7 once provider costs are added. For a typical English outbound call using Deepgram + GPT-4o-mini + a standard TTS voice, total cost lands somewhere in the ₹12–18/min range depending on call length and LLM usage. Indian-language calls using Fennec STT may differ. Run your own numbers using the Bolti pricing calculator.

How Does Bolti Pricing Compare to Bolna AI and Ringg AI?

Prospects most often compare Bolti against Bolna AI and Ringg AI. Here's a factual comparison on the dimensions that matter at evaluation time:

Factor	Bolti	Bolna AI	Ringg AI
Base rate	₹7/min	Varies by plan	Varies by plan
Free trial	50 minutes	Limited	Limited
Indian-language STT	Fennec, Azure, ElevenLabs	Depends on config	Depends on config
BYOC telephony	Twilio, Plivo, Exotel, SIP	Partial	Partial
On-premises option	Yes (enterprise contract)	Not publicly documented	Not publicly documented
Data residency	India by default (E2E Networks)	Not publicly documented	Not publicly documented
API access	Full REST API; every dashboard action is also an API call	Available	Available

For a deeper feature-by-feature breakdown, see the Bolti vs Bolna and Ringg comparison page.

The short version: if India-resident data, Indian-language support, and BYOC telephony are hard requirements, Bolti is built around those from the ground up — not bolted on.

Who Should Choose Pay-As-You-Go vs Enterprise?

Pay-as-you-go at ₹7/min is right for:

• SMBs and startups validating a use case
• Teams with variable call volumes (seasonal campaigns, pilots)
• Developers building and testing agents before scaling

Enterprise contracts make sense when you need:

• On-premises deployment (your own infrastructure, no data leaving your network)
• Sub-accounts and white-label setups for agencies or SaaS platforms
• PII redaction at runtime
• SSO via OIDC/SAML
• DPDP/GDPR/HIPAA-aligned data processing agreements
• Dedicated support and SLA commitments

Enterprise pricing is not self-serve — contact Bolti to discuss architecture and commercial terms.

Hidden Costs to Watch For

Before you commit to any voice AI platform, ask these questions:

1. Are provider costs bundled or separate? Bolti is transparent: ₹7/min is the platform fee; STT/LLM/TTS are separate. Some competitors bundle these at a higher headline rate, which can look cheaper until you model actual usage.
2. What happens to recordings and transcripts? Bolti stores call recordings and transcripts in India by default. Check whether your provider stores data in a jurisdiction you're comfortable with.
3. Is there a minimum monthly commitment? Bolti's pay-as-you-go has none. Verify this with any platform you evaluate.
4. What's the per-number cost? If you're running inbound agents at scale, number rental costs add up. BYOC lets you avoid this entirely.

Start With 50 Free Minutes — No Credit Card Needed

Bolti's free trial gives you 50 minutes of real call time to test an agent end-to-end. That's enough to run a complete outbound campaign sample or stress-test an inbound support flow. After that, you're on ₹7/min pay-as-you-go with no lock-in.

Frequently Asked Questions

What is Bolti's pricing per minute?

Bolti charges ₹7 per minute as the base platform rate on a pay-as-you-go basis. This covers the Bolti runtime — orchestration, turn-taking, noise cancellation, recording, and transcripts. STT, LLM, TTS, and telephony provider costs are additional and depend on which providers you configure.

Does Bolti have a free trial?

Yes. Bolti offers 50 free minutes with no credit card required. You can use these minutes to run a real agent on real calls — not a sandbox demo — before committing to any spend.

Can I use my existing Twilio, Plivo, or Exotel account with Bolti?

Yes. Bolti supports BYOC (bring your own carrier) — you can connect your existing Twilio, Plivo, or Exotel SIP trunk, or register any SIP trunk. Bolti-provided numbers are also available if you don't have a carrier relationship.

How does Bolti pricing compare to Bolna AI and Ringg AI?

Bolti's published base rate is ₹7/min with a 50-minute free trial. Bolna AI and Ringg AI use plan-based pricing that varies by tier. Bolti differentiates on India-resident data storage by default, native Indian-language STT (via Fennec and others), and full BYOC telephony support — factors that affect total cost and compliance fit.

Is there an on-premises or enterprise option?

Yes. Bolti offers on-premises deployment as part of an enterprise contract. This is suited for teams with regulatory requirements around data residency, audio storage, or private network connectivity. Enterprise contracts also include PII redaction at runtime, SSO, and DPDP/GDPR/HIPAA-aligned agreements. Contact Bolti to discuss terms.
