WhatsApp & chat AI agents

WhatsApp AI agent development

An agent on your WhatsApp Business number that answers, shows your catalogue and closes orders — 24/7.

The problem

Your customers already message you on WhatsApp. The problem is that a human has to read every message, and humans sleep, take lunch and answer the same question forty times a week. Enquiries that arrive at 11 PM are answered at 10 AM, by which point the customer has bought somewhere else.

Enquiries stop going cold overnight.

Built for: Shops, D2C brands, clinics, service businesses selling over chat.

What we deliver

  • Official Business API setup. We get you onto the WhatsApp Business Platform properly — verified number, display name, message templates approved. No unofficial libraries that get your number banned.

  • Grounded on your data. The agent reads your actual catalogue, price list, stock levels, delivery zones and refund policy. When it does not know something, it says so and hands over instead of inventing an answer.

  • Native in-chat catalogue. Products appear as WhatsApp list messages and buttons, not as a wall of text or a link that nobody taps.

  • Order and payment flow. Holds stock, sends a verified payment link, confirms the order and posts it into your sheet, CRM or ERP.

  • Human handover. Anything sensitive, angry or out-of-scope routes to your team with the whole conversation attached.

  • Hindi, English, Hinglish. It answers in the language the customer used, including transliterated Hinglish, which is how most Indian customers actually type.

How the build runs

  1. 1

    Week 1 — connect

    We take your catalogue, policies and one WhatsApp number, and stand up the agent on staging. You message it yourself and tell us where it is wrong.

  2. 2

    Week 2 — harden

    We fix the wrong answers, set the guardrails (what it may promise, what it may never say, when it must escalate) and wire the order flow into your system.

  3. 3

    Ongoing — run

    It goes live on your number. We watch real conversations, fix what it fumbles, and report against the number we agreed at the start.

Frequently asked questions

Do you use the official WhatsApp Business API?
Yes. We set you up on the official WhatsApp Business Platform through a Meta partner. Unofficial automation libraries get numbers banned, and a banned number takes your customer history with it.
Can it take payments inside the chat?
It sends a verified payment link from your existing gateway — Razorpay, PayU, Cashfree or whatever you already use — and confirms the order once payment clears. We do not hold your money at any point.
What happens when it does not know the answer?
It says it does not know and hands the chat to a human, with the full conversation attached. We would rather it escalate ten times too often than confidently tell a customer something false about your refund policy.
How fast can it go live?
If you already have a verified WhatsApp Business number and a catalogue in any readable form, a working agent on staging usually takes a few days. Getting a fresh number verified by Meta is the slow part and is outside our control.
