Bolna Alternative: Adya vs Bolna AI
Bolna is one of the cheapest ways to put a voice agent on a phone line in India, and it is built for teams who want to assemble their own stack. Adya is a finished agent for phone, chat, WhatsApp and email. Here is where each wins.
What is Bolna, and how is Adya different?
Bolna is a Y Combinator-backed voice AI platform. Its standard rate is 6¢ (₹5.52) a minute on prepaid credits, it starts with $5 of free credit, and it lets you bring your own LLM, speech-to-text and text-to-speech keys and your own Twilio, Plivo or Vobiz telephony.
Adya is one AI agent that answers phone calls, website chat, WhatsApp and email from a single inbox, with a free plan, ₹6 a minute voice with telephony included, and live human takeover built in.
Choose Adya if…
- You need WhatsApp, website chat and email handled by the same agent
- You want a finished product your support team can run without engineers
- You want telephony and an Indian number bundled into one bill
- You want a shared inbox where humans take over live calls and chats
Choose Bolna if…
- Phone calls are your only channel and cost per minute is the deciding factor
- Your engineers want to pick and swap the LLM, STT and TTS providers
- You already have Twilio, Plivo or Vobiz numbers and contracts
- You need on-premise deployment

Scenario: 1,000 minutes of AI calls a month, excluding GST. Both bills built only from published prices.
Adya Growth

- 500 extra minutes × ₹6₹3,000
Telephony is in the per-minute rate. Also covers 5,000 chat, WhatsApp and email conversations.
Bolna standard rate
- 1,000 min × 6¢ (₹5.52, Bolna's own conversion)₹5,520

Where Bolna is stronger, and where Adya is
We make Adya, so read this section as our view. We have tried to give the other side its due.
Where Bolna wins
- Lower raw cost per minute: 6¢ standard and 4.51¢ at its top volume tier.
- Bring-your-own-keys for LLM, STT and TTS, so engineers can tune quality and cost per provider.
- Developer tooling — batch and SIP trunk APIs and a CLI — plus Zapier, Make and n8n connectors.
- Named Indian customers at scale, including GoKwik and Physics Wallah, and an on-premise option.
Where Adya wins
- Website chat, WhatsApp and email from the same agent. Bolna is phone-only.
- No assembly. Telephony, an Indian number and the voice stack are one product and one bill.
- A shared inbox with live human takeover of calls and chats, plus ticketing.
- A free plan and fixed monthly plans, so a run of calls never stops because prepaid credit ran out.
- Appointment booking with two-way Google Calendar sync, built in.
