Use tool ↗About Tunk
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.

Pros & cons of Tunk
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.
Pros
- Covers both speech-to-text and voice agent building from one account
- Interactive playgrounds for both products, not just API documentation
- Names a real legal entity and registered Indian address on the site
Cons
- Pricing page renders no figures, so the rate is unknown until you sign up
- No published accuracy or latency benchmarks
- Small vendor with thin third-party coverage to corroborate its claims
Best for
- Teams evaluating speech APIs from an India-based vendor
- Building voice agents and transcription against a single provider
- Trying real-time recognition in a browser playground before integrating
Not for
- Buyers who need a published rate card before starting a trial
- Anyone requiring documented accuracy benchmarks against established engines
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.
