Bolna.ai Pricing Explained — Plus a Cheaper Alternative in 2026

Evaluating bolna.ai pricing before deploying your first voice agent? Bolti, a voice AI platform for phone agents, offers a transparent alternative at ₹6/min pay-as-you-go with a 50-minute free trial, helping you avoid unexpected bills when scaling outbound campaigns or support desks.

Is bolna.ai pricing transparent?

Bolna.ai pricing uses a volume-based, pay-as-you-go model where you pay for platform usage plus the individual costs of speech-to-text (STT), large language models (LLMs), text-to-speech (TTS), and telephony. While it has no flat subscription fee, your total bill depends heavily on the markups of the underlying providers you choose.

A typical voice call requires four distinct components, and bolna.ai pricing reflects this multi-layered stack:

• Platform usage fee: The core per-minute rate charged by Bolna AI for orchestrating the call.
• STT (Speech-to-Text) costs: Charged per minute of transcription.
• LLM token costs: Billed per thousand input and output tokens consumed during the conversation.
• TTS (Text-to-Speech) costs: Billed per character generated by the voice synthesis engine.
• Telephony/SIP trunking: The cost of routing calls over the PSTN, which can be optimized if you use BYOC (bringing your own Twilio, Exotel, or Plivo trunk).

What makes bolna.ai pricing unpredictable?

Bolna.ai pricing becomes unpredictable because of markups on the underlying provider layer (STT, LLM, TTS, and telephony) if you do not bring your own API keys. Bundled services often carry significant markups, inflating your final per-minute rate far beyond the base platform fee.

For example, running a high-realism agent in India can quickly become expensive if you use premium global providers:

• High-realism TTS: Using ElevenLabs for natural voice synthesis can add ₹3 to ₹5 per minute.
• Frontier LLMs: Running long, branching conversations on OpenAI's GPT-4o can cost ₹2 to ₹4 per minute in token usage alone.
• STT Latency Trade-offs: While Deepgram is a strong default for English, using global STT engines for Indian regional languages like Hindi, Tamil, or Telugu often leads to poor accuracy, forcing you to pay for longer, repetitive turns.
• Telephony Markups: If you do not connect your own SIP trunk (via Twilio, Plivo, or Exotel), you will pay carrier markups on every outbound dial.

Can you run voice agents cheaper than Bolna AI?

Yes, you can run voice agents more affordably by using Bolti's flat ₹6/min pay-as-you-go orchestration rate and choosing low-cost, high-performance underlying providers directly in your dashboard. This bypasses the bundled markups common in Bolna AI and Ringg AI.

In Bolti's Speech and LLM tabs, you can select specialized, low-cost providers:

• Indian-Language STT: Use Fennec or SarvamAI STT for regional Indian languages (Hindi, Marathi, Tamil, Telugu, Bengali, Gujarati). These perform with native prosody and accuracy, reducing call duration and token waste.
• Custom OSS LLMs via Baseten: Bolti integrates Baseten as a first-class provider. You can run open-source models like DeepSeek-V3.1, Llama-4-Maverick-17B, or Qwen3-235B on dedicated GPU infrastructure. This is often 5–10× cheaper at scale than calling closed APIs like GPT-4o.
• Low-Latency, Low-Cost LLMs: For simple scripted tasks, you can select Llama models served on Groq's accelerators for ultra-low latency and near-zero token costs, or use balanced defaults like Gemini 2 Flash and GPT-4o-mini.

How do you configure and optimize voice agent costs in Bolti?

You can configure your entire cost and performance stack in under 10 minutes using Bolti's agent setup wizard, which organizes your agent's behavior and providers into distinct, easy-to-use tabs. This eliminates the need for complex custom code or developer resources.

• The Basic Tab: Shape who your agent is by setting the display name, choosing a Persona (Helpdesk, Sales, or Healthcare), selecting the Primary language, and defining a single-sentence Goal (e.g., "Qualify the lead by collecting budget and booking a demo").
• The Speech Tab: Select your STT and TTS engines. Choose Deepgram or Cartesia for ultra-low latency English, or Fennec for Indian languages.
• The LLM Tab: Pick your brain. Choose from OpenAI, Google Gemini, Groq, or connect Baseten to run cost-effective open-weights models.

Why does provider choice impact your voice AI budget?

Every voice call requires balancing latency, quality, and cost. Your choice of STT, LLM, TTS, and telephony providers directly dictates whether you pay a premium for high-realism voices or optimize for sub-second response times at a fraction of the cost.

• Latency: How fast the round trip from caller speech to agent reply happens. Anything over ~800ms feels sluggish. STT (like Cartesia or Deepgram) has the biggest impact on perceived latency.
• Quality: Natural voice synthesis (like ElevenLabs) and strong reasoning (like GPT-4o or Gemini 2 Pro) cost more but handle complex, branching conversations better.
• Cost: Every minute on the phone incurs charges for STT minutes, LLM tokens, TTS characters, and telephony routing. Bolti lets you swap these per agent, allowing you to optimize for the exact axis you need.

Does Bolna AI offer a free tier?

Bolna.ai offers a limited free trial to test their platform, but the minute allowance is small and restricted to sandbox testing. For any production-level outbound campaigns, inbound support queues, or automated appointment booking, you must upgrade to a paid tier.

In comparison, Bolti provides a transparent free trial with 50 minutes of actual talk time. This allows you to test real-world calls, connect your own SIP trunks, and run pilots without entering credit card details or talking to a sales representative.

What is the average cost of running a voice AI agent?

On average, mid-market voice AI platforms cost between ₹4 and ₹10 per minute all-in, depending on your choice of LLM, TTS, and telephony routing. Enterprise-grade deployments with custom SLAs and dedicated infrastructure can range from ₹12 to ₹20 per minute.

Here is a benchmark of typical voice AI costs in 2026:

Tier	Typical Cost Range (Per Minute)	Key Characteristics
Budget / Self-hosted	₹1–3/min	Infrastructure costs only; requires high developer overhead to maintain sub-second latency.
Mid-market (Bolna AI, Bolti)	₹4–10/min	Fully managed orchestration, sub-second turn-taking, and easy provider swapping.
Enterprise Managed	₹12–20/min	Custom contracts, dedicated GPU pools, PII redaction, and DPDP/GDPR-aligned compliance.

What are the best alternatives to Bolna AI?

The most common alternatives to Bolna AI are Bolti and Ringg AI, which differ primarily in pricing transparency, regional language support, and developer flexibility. While Ringg AI focuses on unified suites with less public pricing transparency, Bolti offers a flat, publicly documented rate.

• Bolti: Offers a flat ₹6/min pay-as-you-go rate, fully documented on the Bolti pricing page. It features sub-second latency, native Indian language models (Fennec, SarvamAI), and allows you to bring your own SIP trunk (Twilio, Plivo, Exotel) to avoid telephony markup.
• Ringg AI: Positioned as an all-in-one platform, but its pricing structure is opaque and typically requires a sales consultation to get started.
• Bolna.ai: A solid volume-based platform, but costs can quickly escalate due to provider markups if you do not manage your own API keys.

When does paying per-minute for voice AI make financial sense?

Voice AI pricing is highly cost-effective for businesses running high-volume, repetitive phone operations where human agent costs, recruitment overhead, and after-hours staffing fees are high. Replacing manual dialing with an automated voice agent typically reduces operational costs by 60% to 80%.

Common high-ROI use cases include:

• Outbound Sales & Lead Qualification: Automate cold outreach and BDR qualification lists. Agents run 24/7 and route qualified leads directly to your sales team.
• Appointment Booking & Reminders: Automate scheduling and confirmation calls for healthcare clinics, salons, and service centers.
• Payment Reminders: Run structured, polite, and compliant debt collection and payment reminder campaigns at scale.
• Inbound Customer Support: Provide instant, after-hours helpdesk support without paying for night-shift staff.
• HR Screening: Conduct first-round screening calls across hundreds of job applicants simultaneously, filtering for basic qualifications.
