ThinnestAI vs Exotel
Not purely a versus, but not fully 'use both' either — ThinnestAI can't import an Exotel number today, so the carrier layer isn't as interchangeable as it used to be.Exotel is India's leading cloud telephony carrier. ThinnestAI is the voice AI agent brain — buy a number directly from ThinnestAI, or bring your own if it's already with Plivo, Vobiz, Twilio or Telnyx.
TL;DR
- Exotel is a carrier. ThinnestAI is a voice AI platform — most customers buy their number directly from ThinnestAI rather than running the two side by side, since Exotel numbers can't be imported.
- Exotel's voice-bot / AI agent layer is thin compared to specialist voice AI platforms. That's where ThinnestAI fits on top.
- Recommended setup: buy a number directly from ThinnestAI, or bring an existing Plivo, Vobiz, Twilio or Telnyx number via BYOK — Exotel and other carrier numbers can't be imported today.
Decision
Which one to pick
Pick ThinnestAI if
You need the AI conversation layer — LLM, STT, TTS, agent settings, dashboards, INR billing. Buy an Indian number directly from ThinnestAI and skip a separate carrier relationship, or import an existing Plivo, Vobiz, Twilio or Telnyx number.
Pick Exotel if
You only need PSTN connectivity, click-to-call, basic IVR and call recording — no LLM, no real conversation. Exotel's CCaaS does this without an AI platform.
Pick neither if
You're outside India — Exotel is India-only. ThinnestAI's BYOK import supports Plivo, Vobiz, Twilio and Telnyx numbers; talk to sales about non-Indian number options.
Pricing
Pricing note
Exotel's business phone plans start around ₹9,999 for 5 months with 3 agents — credit-based (₹1 = 1 credit). They do not publish a per-minute rate for AI voice agents; voice bot pricing is quote-based. ThinnestAI is ₹2/min on standard voices and ₹2.5/min on premium voices for the voice AI platform layer, telephony included either way, whether you buy a number directly from ThinnestAI or import an existing Plivo, Vobiz, Twilio or Telnyx number. A typical customer either buys a number from ThinnestAI outright, or brings a Plivo, Vobiz, Twilio or Telnyx number via BYOK — Exotel numbers aren't importable today.
