Speech-to-text and voice-agent APIs from an Indian vendor, with browser playgrounds for both
Tunk.ai sells two developer products from one account: a speech-to-text API with real-time recognition, and a voice AI agent builder for automated phone and in-app conversations. Both have browser playgrounds behind a dashboard login, so you can try recognition and an assistant before integrating anything, and the marketing is aimed at industry buyers rather than consumers. It is operated by LogicNimbus Private Limited in Maharashtra, India, with a registered address and support email on the site. The pricing page is rendered client-side and served no figures to any of our fetches; the vendor describes billing as pay-for-what-you-use with volume discounts and quoted enterprise deals, so no entry price is recorded here.
The /pricing page renders client-side and returned no plan names, rates or figures across repeated fetches. The vendor describes usage-based billing that scales with volume, with discounts at higher tiers and quoted enterprise pricing. Since no number was legible, none is recorded.
Use tool ↗A small Indian voice-AI vendor covering both halves of the stack — recognition and agents — with playgrounds you can poke at before wiring anything up. What we could not establish is the thing that decides whether it is worth trying: the rate. Nothing on the site rendered a price for us, and there is little third-party coverage to check it against.
Watch out: Budget for a sales conversation: the pricing page produced no number in any of our fetches, and the vendor's own description of billing points at a quote rather than self-serve checkout.
