Multi-Channel Chatbot System
One AI chatbot across website, WhatsApp, Instagram, Messenger, and SMS with unified memory and CRM sync.
Overview
What we built
An AI-powered chatbot that responds to customer inquiries across multiple channels simultaneously—website, WhatsApp, Instagram DMs, Facebook Messenger, and SMS—with unified conversation memory and context.
The challenge
Why automation was needed
Businesses were losing leads because they couldn't respond fast enough across channels.
- Missing leads because responses weren't fast enough across multiple channels
- Support teams overwhelmed with repetitive questions about pricing, availability, and FAQs
- Different team members handling different channels with no shared context
- Inconsistent responses across channels and time of day
The solution
