ThinnestAI vs Haptik
Haptik (Jio Platforms) is India's biggest chat-first conversational AI. ThinnestAI is voice-first and dev-first. Here's the honest framing.
- Haptik is chat-first, WhatsApp-native. ThinnestAI is voice-first. Feature overlap on voice is limited — Haptik's voice is newer and thinner than its chat.
- Haptik has unbeatable WhatsApp distribution via the Jio ecosystem. ThinnestAI has native phone / SIP for real voice agents.
- If you need WhatsApp + light voice, pick Haptik. If you need a serious voice agent platform with BYOK, pick ThinnestAI.
Pricing note
Haptik partially publishes pricing: a ₹10,000 starter bundle for SMB WhatsApp + voice AI agents (~2,000 conversations, effective ~₹5/conversation). Enterprise is quote-based. No published per-minute voice rate. ThinnestAI is a flat ₹1.5/min for voice, with BYOK provider pass-through.

You need WhatsApp-first distribution
- You are an Indian SMB and want the cheapest WhatsApp + light voice bundle on the market (₹10K starter).
- WhatsApp Business is your primary channel — voice is a 'nice to have'.
- Jio ecosystem distribution matters more to you than technical flexibility.
- You want a single vendor for chat and voice without building it yourself.
You need a serious voice agent platform
- Voice is your primary channel — inbound calls, outbound campaigns, phone support.
- You need BYOK — your own LLM, STT and TTS providers per agent.
- You need DLT-compliant Indian phone numbers, native SIP integration.
- You want a flat, predictable ₹1.5/min voice rate, not quote-based.
Frequently asked questions
Is Haptik really chat-first? I thought they had voice now.
+
Haptik does have voice — it's a real product. But their DNA and brand gravity are chat (specifically WhatsApp via the Jio ecosystem). For voice agent maturity (flow editor depth, phone ops, BYOK providers) specialist voice platforms like ThinnestAI have an edge.
Can ThinnestAI do WhatsApp like Haptik does?
+
Basic chat yes, native WhatsApp Business API integration no — this is a Haptik strength. If WhatsApp is your primary channel, Haptik wins on distribution alone.
Which one is cheaper?
+
Haptik's ₹10K SMB bundle is cheap for chat at small scale. For pure voice at scale, ThinnestAI's flat ₹1.5/min is almost certainly cheaper — Haptik does not publish a per-minute voice rate.
When is Haptik clearly the right choice?
+
When you are a small-to-mid Indian business whose primary channel is WhatsApp, you need a bundled chat + light voice product, and Jio ecosystem distribution is valuable to you.
