The problem it solves

Customers ask the same questions about your products, policies, or hours over and over, and answering each one by hand on WhatsApp eats into your day. You want fast, accurate replies without hiring someone to sit on the phone all day.

Who it fits

A business offering customer support or FAQs over WhatsApp that wants instant, accurate answers around the clock.

How it works

  1. A customer sends a message on WhatsApp
  2. The system checks whether it's a document upload or a question
  3. Uploaded documents are converted into a searchable knowledge base
  4. Questions are matched against that knowledge base for relevant context
  5. An AI assistant writes an answer and sends it back on WhatsApp
What you get

Customer questions answered without a staff member typing

You get an always-on WhatsApp assistant that answers customer questions directly from your own documents, day or night.

What you get

Automatic, accurate WhatsApp replies drawn from your own documents, available any time of day.

What you need

A WhatsApp Business API account, a Supabase account, and OpenAI and Google Gemini API keys.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
