If your only need is a raw, low-level Voice AI API to embed inside software your own engineers are building, and you already own the CRM, follow-up and telephony around it, a developer-first platform like Bolna can be the tighter fit. GRX10 is built for teams that want the outcome, not the plumbing.
Bolna lists $0.06 per minute pay-as-you-go, with telephony and its platform fee added per minute, on bolna.ai/pricing (as of 17 October 2026). GRX10 Voice AI is ₹7.99 ($0.119) per minute plus telephony at carrier cost, billed per minute and rounded up to the next full minute, and includes CRM logging and follow-up. Compare the full per-call cost in the Bolna pricing guide.
Bolna is a developer-first platform you build on. GRX10 is a ready agent: you describe the job in one sentence, review the generated script and voice, and go live, or have the GRX10 team run it.
Both build voice agents for Indian languages. GRX10 runs one speech-to-speech model that follows callers who switch between Hindi and English mid-sentence.
GRX10 includes MicroCRM and Nudge, so every call is logged and followed up. With Bolna you bring your own CRM, follow-up and telephony.
