The report card
Best for voice AI agents with Indian-language support
Bolna builds phone agents without code and supports Indian languages, billed per minute from 6 cents with bundled models. Telephony and a platform fee are added on top. Calls stop when credits run out unless you set automatic top-ups.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | $0.06 a minute on pay-as-you-go with bundled models, from a $10 credit purchase. Telephony and a platform fee are added per minute, so the real rate is higher. |
| Free plan and trial | C | $5 in free credits on sign-up. No card is mentioned, but it is only a few minutes of calls. |
| Features | C | No-code builder and API, Indian-language voice, bulk campaigns, live API calls and human handoff. Pilot rates hold only until the purchased minutes run out. |
| Ease of use | C | No store rating on record. You build the agent, pick models and connect a phone provider such as Twilio. |
| Platforms and integrations | B | Web dashboard and API, with n8n, Make, Zapier, Twilio and Plivo listed. No desktop or phone app. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Bolna you would be making an AI agent, with the models and the safeguards behind it. That is not a weekend's work, with an AI app builder or without one.
What you could not
- An AI agent, with the models and the safeguards behind it.
- Connections to other products, each kept working as those products change.
- A builder that other people can use without writing code.
What this rests on. Bolna’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
