1.Why Use an LLM Chatbot?
- Enhances user engagement by offering instant, contextual answers
- Qualifies leads through guided conversation flows
- Demonstrates AI capabilities, building trust for SaaS and AI-focused sites
2.Selecting Your LLM Provider & API Keys
- Compare OpenAI, Anthropic, and open-source options (models, pricing, latency)
- Securely store API keys in Webflow environment variables or a serverless function
3.Embedding in Webflow: HTML Embed & Custom Code
- Create an HTML Embed Component in Webflow Designer
- Insert the basic widget container:
<div id="chat-widget"></div>
<script src="chatbot.js"></script>
- Load your custom
chatbot.js
that initializes the chat via API calls
4.Styling with Webflow Classes & Interactions
- Use Webflow’s style panel to assign classes to chatbot container elements
- Add interactions for open/close toggles and incoming message animations
- Ensure mobile responsiveness: fixed bottom positioning with safe-area insets
5.UX Best Practices: Onboarding Prompts & Fallbacks
- Start with a friendly greeting: “Hi there! How can I help you today?”
- Provide quick-reply buttons for common tasks
- Implement fallback responses when the model fails to answer accurately
- Track intents to improve conversation flows over time
6.Privacy & Compliance: GDPR, Data Logging
- Display a consent banner before chat activation
- Anonymize user inputs and avoid logging PII
- Provide a link to your privacy policy within the chat widget
7.Troubleshooting & Performance Tips
- Monitor API error rates and implement exponential backoff
- Lazy-load the chatbot script after user scroll or click
- Cache static responses where appropriate to reduce API calls
