Slightly gummy. The crust never quite set.
Summary
ThinnestAI is a voice AI infrastructure platform founded by Ashutosh that enables building voice agents in 100+ Indian languages at a flat ₹1.5/min platform fee with INR billing. The platform was created after the founder struggled to find a solution that supported native Hindi voice agents without USD billing or model lock-in. It offers bring-your-own-key (BYOK) support for major LLM, STT, and TTS providers, native SIP/Twilio integrations, a no-code flow builder, and real-time voice agents for customer support, sales, and operations.
Key quotes
· 5 pulledSix months ago I tried building a Hindi voice agent for a friend's NBFC. The platforms I tried either spoke broken Hindi, billed in USD with FX markup, or locked me into one model provider with no way to use the API keys I already paid for.
So we built the missing layer. ThinnestAI is voice AI infrastructure.
→ Flat ₹1.5/min platform fee — INR billing.
→ 100+ Indian languages — native STT + TTS pipelines per language, not English-with-translation
→ Optional BYOK on OpenAI / Anthropic / Google / Deepgram / Sarvam / Cartesia / ElevenLabs
