Free AI Chatbot for Your Website: Complete Setup Guide

Adding an AI chatbot to your website used to require developer expertise, expensive subscriptions, and weeks of setup. In 2026, that's no longer the case. You can have a fully functional AI chatbot live on your site in under 5 minutes — completely free, with no coding and no credit card.

This guide walks you through the entire process step by step, from signing up to embedding the chatbot on your website. Whether you run a small business, an online store, or a SaaS product, this tutorial has you covered.

Why Your Website Needs an AI Chatbot

Before we dive into the setup, let's look at why an AI chatbot is no longer optional for modern websites:

24/7 instant support. Your visitors don't wait for business hours. An AI chatbot answers questions the moment they're asked — at 2 AM on a Sunday or during your busiest sales day. No queue, no hold music, no "we'll get back to you within 24 hours."

Automatic lead capture. Every conversation is an opportunity. AI chatbots naturally collect visitor emails, phone numbers, and company names during the conversation flow. Instead of hoping someone fills out your contact form, the chatbot captures leads while actually helping people.

Massive cost savings. Hiring a live support agent costs $35,000–$55,000 per year. An AI chatbot handles unlimited simultaneous conversations for a fraction of that cost — or in this case, for free.

Higher conversions. Studies show that websites with chatbots see 30–50% more conversions than those relying on static forms alone. When visitors get instant answers to their questions, they're far more likely to buy, sign up, or book a call.

What You Get With Chatonbo's Free Plan

Chatonbo's free plan isn't a limited trial — it's a permanent free tier designed for small businesses and anyone getting started with AI chatbots. Here's what's included:

• 1 AI agent — a fully customizable chatbot for your website
• 250 conversations per month — enough for most small business websites
• Multi-language support — auto-detects your visitor's language and responds naturally in 14+ languages
• Knowledge base (3 sources) — upload PDFs, add your website URL, or create FAQ entries so the bot answers accurately
• Lead capture — automatically collects visitor contact information
• Works on any website — WordPress, Shopify, Wix, Squarespace, custom HTML, or any platform
• No credit card required — sign up and start using it immediately

If you outgrow the free plan, you can upgrade to Pro ($19/month) or Business ($59/month) at any time for more conversations, unlimited knowledge sources, and team collaboration features.

Step-by-Step Setup: Your First AI Chatbot in 5 Minutes

Step 1: Create Your Free Account

Head to chatonbo.com/register and sign up with your email address or Google account. The entire process takes about 30 seconds. No credit card, no phone number, no lengthy onboarding questionnaire.

Once you're in, you'll land on your dashboard — clean, simple, and ready to go.

Step 2: Create Your First Bot

Click "Create Bot" on your dashboard. You'll need to fill in three things:

• Bot name — give it a name like "Support Bot" or "Sales Assistant" (visitors won't see this)
• Website domain — enter the domain where the chatbot will live (e.g., yoursite.com)
• Template — choose from pre-built templates like Customer Support Agent, Sales Agent, or start from scratch

Templates come with pre-written bot instructions optimized for common use cases, so your chatbot is smart right out of the box.

Step 3: Add Your Knowledge Base

This is what makes your chatbot actually useful. Instead of giving generic answers, it responds based on your specific business information. You have three ways to add knowledge:

Upload a PDF: Got a product manual, FAQ document, or service guide? Upload it directly. The AI reads and understands the content so it can answer questions about it.

Add a website URL: Point the bot to your website, help center, or documentation pages. It will crawl the content and use it as reference material.

Create FAQ entries: Manually add question-and-answer pairs for the most common questions your customers ask.

On the free plan, you can add up to 3 knowledge sources. That's usually plenty to cover your core product information, pricing, and common questions.

Step 4: Copy the Embed Code

Once your bot is configured, navigate to the "Embed" section in your bot settings. You'll see a single line of HTML code that looks like this:

<script src="https://chatonbo.com/widget/chatonbo-widget.js" data-bot-id="YOUR-BOT-ID"></script>

Copy this code — you'll paste it into your website in the next step.

Step 5: Add the Chatbot to Your Website

Paste the embed code into your website, just before the closing </body> tag. Here's how to do it on the most popular platforms:

WordPress:

Go to Appearance → Theme File Editor (or use a plugin like "Insert Headers and Footers"). Paste the code in the footer section, just before </body>. For a detailed walkthrough, see our WordPress chatbot guide.

Shopify:

Go to Online Store → Themes → Edit Code. Open theme.liquid and paste the embed code before the closing </body> tag. Check out our Shopify AI chatbot guide for tips on product recommendations and cart recovery.

Wix:

Go to Settings → Custom Code. Click "Add Custom Code," paste the embed snippet, set it to load on all pages in the body (end). Save and publish.

Any HTML Website:

Open your main HTML file (usually index.html) and paste the script tag right before </body>. That's it — one line, and your chatbot is live.

After saving, visit your website and you'll see the chat bubble appear in the bottom-right corner. Click it, ask a question, and watch your AI chatbot respond based on the knowledge you provided.

Customization Tips

Your chatbot is live — now let's make it yours.

Match your brand colors. In the bot settings, you can change the primary color, text color, and chat bubble style to match your website design. A chatbot that looks native to your site builds more trust with visitors.

Set up lead capture properly. Enable the lead capture form to collect emails and names before or during the conversation. You can set it to appear after the first message, after a few exchanges, or only when the visitor asks about pricing or contact information.

Write clear bot instructions. The bot instructions tell the AI how to behave. Be specific: "You are a helpful support agent for [Company Name]. You help visitors learn about our services and answer questions about pricing. Always be friendly and professional. If someone asks about something you don't know, suggest they email [email protected]." Good instructions make a huge difference in response quality.

Test before going live. Use the built-in chat preview in your dashboard to test different scenarios. Ask questions your customers would ask. Check that the bot pulls the right information from your knowledge base. Adjust instructions if needed.

When you reach your monthly limit, the chatbot will pause until the next billing cycle. You can upgrade to Pro ($19/month) for 5,000 conversations or Business ($59/month) for 10,000 conversations. Your conversation count resets every month.

Yes, upgrading is instant. Go to Pricing in your dashboard and choose a plan. Your chatbot, knowledge base, conversation history, and all settings carry over — nothing is lost.
