The Problem

Support teams buried in repetitive product questions

01

Customers ask the same questions about sizing, shipping, and returns — over and over

02

After-hours inquiries go unanswered, leading to abandoned carts

03

Product info is scattered across PDFs, help docs, and internal wikis

04

Support agents spend most of their time on copy-paste answers instead of complex issues

The Solution

AI assistant trained on your product catalog and policies

An AI chatbot that ingests your product documentation, FAQ pages, and return policies — then answers customer questions with accurate, citation-backed responses. Deployed on your website widget and WhatsApp so customers get instant help wherever they reach out.
