Step 1: Gather and Prepare Your Knowledge Base

The accuracy of an AI chatbot depends entirely on the clarity of its reference materials:

• Product & Service Pages: Compile links to your landing pages, pricing tiers, and service breakdowns.
• Support FAQs: Export common questions and answers into a clean Word document or Notion export.
• Policy Guidelines: Include your return policy, shipping timelines, revision caps, and contact information.

[!TIP]

Structure critical business rules in Q&A format. Clear questions paired with direct answers produce the highest retrieval accuracy in vector databases.

Step 3: Define Character & Guardrail Instructions

Under the Settings $\rightarrow$ Model tab, instruct your chatbot on how to behave:

Adjust the Temperature slider to 0.1 or 0.2. A low temperature prevents hallucinations and ensures the model adheres strictly to your provided facts.

Step 4: Customize the Chat Widget Appearance

Under the Settings $\rightarrow$ Chat Interface tab:

• Set your primary brand color to match your site design.
• Upload your company logo as the avatar.
• Craft a welcoming greeting (e.g., "👋 Hi there! I'm your AI assistant. Ask me anything about our services or pricing!").
• Add clickable suggested prompt chips like "What are your plans?" or "How do revisions work?".

Step 5: Test and Refine Responses

Before embedding the bot on your public site, run test queries in the built-in sandbox:

• Test edge cases: "Can I get a 90% discount if I ask nicely?"
• Test factual lookups: "What is your refund policy within the first 14 days?"
• Review the Sources citations beneath answers to verify which documentation sections the bot referenced.

Step 6: Embed on Your Website
