Thinnest AI
Thinnest AI · Chatbot
Thinnest AI is a platform for building voice and chat AI agents that answer a business's customers on the phone, WhatsApp, Telegram and a website widget. One agent covers all four channels and keeps the same memory of each customer across them. It hands off to a human when a conversation needs one. The product is built in India with INR billing, data held in GCP Mumbai, and replies in 37 languages. That count takes in all 22 scheduled Indian languages in native script.
About Thinnest AI
What Is Thinnest AI
Thinnest AI is a customer-facing AI agent platform. You point it at a knowledge base, connect your channels, and it answers inbound questions, runs outbound calling campaigns, and captures leads without a human sitting on every chat.
The part that sets it apart is cross-channel memory. A caller on the phone gets matched to their WhatsApp and web history by phone number. So the agent already knows who's on the line. It links records rather than merging them, and it won't reveal what was said on another channel until the person verifies their identity. That's a deliberate limit. Caller ID can be spoofed, so total recall on demand would hand a stranger your account history.
The ceiling is compliance-shaped, not technical. India-specific guardrails like 9am-9pm IST calling hours and TRAI DND scrubbing are baked in, and the fuller DPDPA suite starts on the Scale plan. If you're running a small global shop outside India, the India-first billing and number story may be more than you need.
Getting Started
- Sign up for the Trial, which needs no card and includes 25 voice minutes plus 200 chat replies.
- Upload your knowledge base and pick a voice and reply language. The same knowledge base serves all 37 languages.
- Connect your channels: drop in the one-line web widget, link WhatsApp through Meta's Embedded Signup, or add Telegram and a phone number.
- Test an inbound call or chat, then set escalation rules so the agent hands off to a human in the shared inbox.
- Move to Pay As You Go when you're happy with it, and top up the wallet to keep usage running.

Key features
Cross-Channel Memory With a Built-In Limit
The agent recognizes a returning customer across the phone, WhatsApp, Telegram and web by phone number, so history travels with them onto a live call. Records stay linked rather than merged, and the agent withholds what was said elsewhere until the person verifies who they're talking to. Customers who want total recall on demand usually don't realize that anyone could ring in claiming to be someone else.
One All-Inclusive Per-Minute Rate
Voice pricing is ₹2/min on standard voices and ₹2.5/min on premium ones. That single number covers telephony, speech recognition, the model and the voice. No per-language surcharge. No separate provider bills to reconcile either. Calls on Thinnest AI's own lines bill in 30-second pulses, so a 40-second call bills as 60 seconds instead of rounding up to a full two minutes.
Four Channels From One Agent
The same agent answers on a one-line web widget, a WhatsApp AI agent built on Meta's Cloud API, Telegram, and the phone. That covers inbound, outbound and in-browser web calls. Because it's an approved Meta Tech Provider, WhatsApp onboarding runs self-serve through Embedded Signup. So you're not maintaining separate bots that each forget the customer.
Outbound Calling Campaigns
The platform runs outbound calls with number pooling, pacing, smart retry, voicemail detection and callback scheduling. That makes it a capable AI phone agent for teams that reach out first. Pair it with WhatsApp broadcasts and drip sequences and proactive outreach scales past what a human team can manage. Lead capture happens mid-conversation. Qualified leads land in a shared inbox.
37 Reply Languages
Thinnest AI answers in 37 languages. The list covers all 22 scheduled Indian languages in native script, plus Hinglish code-switching for the way people actually talk. One knowledge base serves every language, so you don't maintain separate content per locale. Need a multilingual AI agent that keeps up when your audience mixes English and Hindi mid-sentence? This is where it earns its keep.
India-First Compliance and Billing
Every plan is time-boxed to 9am-9pm IST calls. TRAI DND/NCPR scrubbing plus the DPDPA compliance suite start on Scale. Enterprise adds a contracted data-residency guarantee in India that an MSA puts a signature to, not just an infrastructure fact. Billing is in INR with a GST invoice, and data sits in GCP Mumbai.
Account Health and Observability
The dashboard surfaces template quality warnings before Meta pauses your sends, restrictions that lift themselves, Meta's opt-out signal, and a failure reason per recipient instead of one number for a whole campaign. That last one matters. Teams that run WhatsApp at volume need to know which recipient failed and why. It saves a lot of blind guessing.
Pros and cons
Pros
- Cross-channel memory keeps customer context intact across the phone, WhatsApp, Telegram and web.
- One all-inclusive rate covers telephony, speech recognition, the model and the voice, so there's no provider bill to chase.
- 30-second billing pulses on its own lines make short calls cheaper than whole-minute rounding.
- Self-serve WhatsApp onboarding through Meta's Embedded Signup cuts setup friction.
- India-first compliance, INR billing and GCP Mumbai data residency suit local businesses.
Cons
- India-centric pricing in rupees and TRAI/DPDPA compliance mean less value if you operate outside India.
- TRAI DND scrubbing and the DPDPA compliance suite aren't on the Trial or Pay As You Go plans, so you'll need Scale for them.
- WhatsApp calls bill by the whole minute at ₹2.5/min, and Meta's per-conversation charges sit on top.
- Enterprise has no published per-minute rate, so you'll need to contact sales for a quote.
