🤖 How We Built a Free AI Customer Support Assistant in 3 Hours
A complete case study on implementing an intelligent chatbot using Botpress, WordPress, and zero monthly costs
📖 Project Overview
At SamaBrains, we believe in leveraging cutting-edge technology to solve real business problems. When we needed a customer support solution that could handle inquiries 24/7, answer questions intelligently using our website content, and do it all at zero cost, we knew we had to build something special.
This case study documents our complete journey of building, deploying, and maintaining an AI-powered customer support assistant that now serves our customers around the clock. The best part? It’s completely free, takes only hours to implement, and requires no coding expertise to maintain.
🎯 The Challenge
Like many growing businesses, we faced several customer support challenges:
- Limited availability: Our team couldn’t provide 24/7 support
- Repetitive questions: Same questions asked multiple times daily
- Slow response times: Customers waiting hours for simple answers
- Budget constraints: Couldn’t afford expensive chatbot solutions
- Website integration: Needed seamless WordPress integration
- Mobile experience: Had to work flawlessly on all devices
We needed a solution that was intelligent, cost-effective, easy to implement, and could grow with our business.
💡 Our Solution
After researching various platforms, we chose Botpress Cloud combined with our existing WordPress website. Here’s why:
🛠️ Technology Stack
We built our solution using these powerful, proven technologies:
🏗️ System Architecture
Our solution follows a modern, scalable architecture that separates concerns and ensures reliability:
The system works through a simple yet powerful flow: users visit our website, WordPress injects the chat widget code, the widget loads from Botpress’s global CDN, and the AI processes queries using our website’s knowledge base in real-time.
⏱️ Development Timeline
Here’s the complete breakdown of our implementation process:
✨ Key Features Implemented
1. Intelligent Knowledge Base
Our chatbot uses Retrieval Augmented Generation (RAG) technology to understand and answer questions based on our website content. It automatically crawls our website, indexes the content, and uses AI to generate natural, contextual responses.
2. Mobile-First Design
The chat interface adapts intelligently to screen size:
- Mobile: Fullscreen takeover for immersive experience
- Desktop: Elegant 400x600px popup in bottom-right corner
- Tablet: Optimized sizing that works perfectly
3. Zero Branding
We implemented custom CSS to completely remove all “Powered by Botpress” branding, giving us a professional, white-labeled appearance that matches our brand identity perfectly.
4. Auto-Open Behavior
The chat automatically opens when users visit our site, maximizing visibility and engagement without being intrusive. Users can easily close it if they don’t need assistance.
5. Contact Integration
The chat header displays our email (info@samabrains.com) and phone number (+256 759 910596) with clickable links for easy communication.
📊 Results & Impact
The implementation has delivered impressive results for our business:
💻 Technical Implementation Highlights
The Core Code
The entire implementation requires just one code snippet added to WordPress. Here’s a simplified view of the structure:
<script src="https://cdn.botpress.cloud/webchat/v3.3/inject.js"></script>
<style>
/* Mobile-responsive chat container */
#webchat .bpWebchat {
position: fixed !important;
bottom: 0; right: 0;
width: 400px; height: 600px;
}
@media (max-width: 768px) {
#webchat .bpWebchat {
width: 100vw !important;
height: 100vh !important;
}
}
/* Hide Botpress branding */
#webchat .bpPoweredBy { display: none !important; }
</style>
<script>
window.botpress.on("webchat:ready", () => {
window.botpress.open();
});
window.botpress.init({
botId: "YOUR_BOT_ID",
clientId: "YOUR_CLIENT_ID",
selector: "#webchat"
});
</script>
📚 Key Lessons Learned
1. Platform Selection Matters
We evaluated multiple platforms before choosing Botpress. The free tier, combined with robust features and easy customization, made it the clear winner for our needs.
2. Mobile-First is Essential
Over 60% of our website traffic comes from mobile devices. Ensuring the chat worked flawlessly on mobile was critical and required careful CSS media queries and testing.
3. Knowledge Base Quality = Response Quality
The chatbot is only as good as the content it learns from. We spent time ensuring our website had clear, comprehensive information for the bot to reference.
4. Testing is Non-Negotiable
We tested on iPhone 7, Samsung Galaxy, iPad, and various desktop browsers. Each platform had unique quirks that needed addressing.
5. User Experience Over Features
We disabled sounds and enabled auto-open for better UX. Sometimes less is more when it comes to features.
🔧 Ongoing Maintenance
One of the best aspects of this solution is the minimal maintenance required:
| Frequency | Task | Time Required |
|---|---|---|
| Weekly | Review conversation logs | 15 minutes |
| Monthly | Update knowledge base (if website changes) | 30 minutes |
| As Needed | Answer complex queries bot can’t handle | Variable |
The chatbot automatically re-indexes our website content, so updates to our site are reflected in bot responses without any manual intervention.
