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.
You need the AI conversation layer — LLM, STT, TTS, flow editor, dashboards, INR billing. Buy an Indian number directly from ThinnestAI and skip a separate carrier relationship, or import an existing Plivo number.
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.
You're outside India — Exotel is India-only. ThinnestAI's BYOK import currently supports Plivo numbers only; talk to sales about non-Indian number options.
- 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 number via BYOK — Exotel and other carrier numbers can't be imported today.
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 They do not publish a per-minute rate for AI voice agents; voice bot pricing is quote-based.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 for the voice AI platform layer, telephony included, whether you buy a number directly from ThinnestAI or import an existing Plivo number. A typical customer either buys a number from ThinnestAI outright, or brings a Plivo number via BYOK — Exotel numbers aren't importable today.

Frequently asked questions
Should I pick Exotel or ThinnestAI?
+
Depends on your number. If you're happy buying a number directly from ThinnestAI (or you already have a Plivo number to import), ThinnestAI covers the full stack — carrier plus AI agent — so there's no separate telco to manage. If you specifically need to keep an existing Exotel number, that's not supported for import today; you'd move to a ThinnestAI-provisioned or Plivo number instead.
Can I use Exotel's SIP trunk with ThinnestAI?
+
Not today. ThinnestAI's BYOK number import currently supports Plivo only — Exotel SIP trunk integration isn't available, even on request. If keeping your specific Exotel number is a hard requirement, ThinnestAI isn't the right fit yet; otherwise buy a number from us directly or import a Plivo number.
Is Exotel's own voice bot good enough?
+
For basic IVR-style flows with Hindi/English/Hinglish, yes. For advanced LLM-driven agents with branching, tool calls, multi-provider routing and Indic language quality, a specialist voice AI platform like ThinnestAI is purpose-built for that layer.
Can ThinnestAI replace Exotel entirely?
+
For the voice-AI-agent use case, largely yes — buy an Indian number directly from ThinnestAI and there's no separate carrier relationship to manage, or import an existing Plivo number if you already have one. We're not a full CCaaS like Exotel (no standalone IVR-only plans, click-to-call widgets, etc.), and we can't import numbers from Exotel or other carriers today.
