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

  1. Create an HTML Embed Component in Webflow Designer
  2. Insert the basic widget container:
<div id="chat-widget"></div>
<script src="chatbot.js"></script>
  1. 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
