Getting Started
This guide will take you from zero to a fully functional chatbot embedded on your website in about 10 minutes.
Creating Your Account
Navigate to the Lumi dashboard and click Sign Up. You'll need an email address and a secure password. After submitting, you can log in immediately—no email verification required.
Configuring Your First Bot
Once logged in, head to the Widgets section and click Create Widget. This is where you'll define your bot's core identity.
Essential Settings
Give your bot a name that users will see in the chat header. This could be "Support Assistant", "Sales Guide", or simply your company name. Next, specify your website URL—this is crucial for CORS security and ensures the widget only runs on your domain.
The greeting message is what users see when they first open the chat. Something welcoming like "Hi there! How can I help you today?" works well. The placeholder text appears in the input field, guiding users on what to ask.
Defining Personality Through System Prompts
The system prompt is your bot's instruction manual. This is where you define tone, boundaries, and behavior. Here's an effective example:
You are a helpful customer support assistant for Acme Corp.
Answer questions clearly and concisely based on the knowledge base.
If you don't have information, say "I don't have that information"
rather than guessing. Be friendly but professional.Keep it focused and specific. Avoid overly long prompts—the bot performs best with clear, direct instructions.
LLM Configuration
The default model is llama-3.3-70b-versatile, which offers excellent performance for most use cases. Temperature is set to 0.7, striking a balance between creativity and consistency. You can adjust these in the settings if needed, though the defaults work well for most applications.
The system automatically rotates between four Groq API keys, ensuring high availability even under heavy load.
Embedding on Your Website
Once your widget is configured, navigate to the Embed tab. You'll see a code snippet that looks like this:
Copy this code and paste it into your website's HTML, just before the closing </body> tag. The widget will appear as a chat bubble in the bottom-right corner of your page.
After pasting, save your file and upload it to your server. Hard refresh your browser (Ctrl+Shift+R or Cmd+Shift+R) to see the widget appear. Click it to open the chat interface and send a test message.
What's Next
Your bot is live, but it doesn't know much yet. The next step is building a knowledge base through our memory and RAG system, which we'll cover in the next guide.
