What Kind of AI Chatbot Can You Build for Free?

What free chatbot plans typically provide:
- A functioning AI chatbot on your website

What requires payment:

Step 1: Create Your Free Tidio Account
Go to tidio.com and click “Get started free.” Sign up with your email, Google, or Facebook account. No credit card required.
Step 2: Add Tidio to Your Website
For WordPress:
- In your Tidio dashboard, go to Settings → Integrations

- In WordPress admin, go to Plugins → Add New → search “Tidio”
- Install and activate the Tidio plugin

- Paste it before the
</body>tag in your website’s HTML
Step 3: Set Up Your Chat Widget
In the Tidio dashboard, go to Channels → Live Chat → Customize:
- Upload your logo or business photo
- Set the widget color to match your brand
- Write a welcome message: “Hi! I’m [Business Name]’s AI assistant. How can I help you today?”
- Set business hours for live chat availability
Step 4: Train Lyro AI on Your FAQ Content
This is the most important step in learning how to build an AI chatbot for free — the AI needs to know your business to give accurate answers.
Go to Lyro AI → Knowledge Base:
- Add your most common customer questions and answers
- Upload your FAQ page content
- Add product/service descriptions
- Include pricing information, hours, location, and policies
Format each entry as:
- Question: “What are your business hours?”
- Answer: “We are open Monday through Friday 9am to 6pm Eastern Time and Saturday 10am to 4pm. We are closed Sundays and major US holidays.”
Add at least 15 to 20 FAQ entries for Lyro to provide useful automated responses.
Step 5: Create Conversation Flows (Automation)
Go to Automation → Create new automation:
Create these essential flows for any business:
Welcome flow:
- Trigger: Visitor spends 10 seconds on homepage
- Action: Send message → “Welcome to [Business]! Are you looking for information about our [services/products]?”
- Options: Show buttons → “Yes, tell me more” / “I have a question” / “Just browsing”
Lead capture flow:
- Trigger: Visitor clicks “I have a question”
- Actions: Ask for name → Ask for email → Ask their question → Thank them and promise follow-up
Returning visitor flow:
- Trigger: Returning visitor (cookie-based)
- Action: “Welcome back! Is there anything I can help you with today?”
Step 6: Test Your Chatbot
Before going live, test every conversation flow. Use your website’s chat widget yourself and ask the questions your real customers ask. Fix any gaps in your FAQ training or conversation flows.
Step 7: Monitor and Improve
After 2 weeks of operation, check Tidio’s analytics:
- Which questions does the AI fail to answer? Add those to your knowledge base.
- Which flows have the highest drop-off? Simplify those steps.
- Are visitors engaging with the chatbot? Adjust the trigger timing if needed.
Method 2: How to Build an AI Chatbot for Free Using HubSpot
Best for: Businesses that want chatbot integrated with a free CRM
Free plan: Unlimited chatbot conversations, full CRM included
Time to deploy: 45 to 60 minutes
HubSpot’s free chatbot builder is the best choice for businesses that want every chatbot conversation connected to a CRM contact record automatically — making it the most business-intelligence-rich free chatbot option available.
Step 1: Create Your Free HubSpot Account
Go to hubspot.com and click “Get started free.” The free forever plan includes the chatbot builder, CRM, and basic automation — no credit card required.
Step 2: Access the Chatbot Builder
In HubSpot, go to Conversations → Chatflows → Create chatflow:
- Select “Website” as the channel
- Choose “Bot” as the chatflow type
- Select your connected inbox (create a free inbox if prompted)
Step 3: Design Your Bot Flow
HubSpot uses a visual flow builder with drag-and-drop elements:
Start with the welcome message node: “Hi there! I’m [Business]’s virtual assistant. I can help you with information about our services, schedule a call, or connect you with our team. What brings you here today?”
Add response branches:
- Branch 1: “Learn about services” → Send information message → Offer to book a call
- Branch 2: “Get pricing” → Send pricing overview → Capture email for detailed quote
- Branch 3: “Talk to someone” → Collect name and email → Create ticket → Promise follow-up
Add a meeting scheduler node: Connect HubSpot’s free meeting scheduler — visitors can book directly from the chatbot. Link your Google Calendar or Outlook calendar for automatic availability.
Step 4: Set Targeting Rules
Control when the chatbot appears:
- Target URL: Show only on specific pages (homepage, pricing page, contact page)
- Visitor behavior: Show after 30 seconds on page
- Device: Desktop only or all devices
- Visitor status: New visitors only vs. returning
Step 5: Connect to Your Website
WordPress: Install the free HubSpot WordPress plugin from the WordPress plugin directory. Connect your HubSpot account. The chatbot appears automatically.
Any website: Copy the HubSpot tracking code from Settings → Tracking Code and paste it before </body> on every page.
Step 6: Activate and Monitor
Go live by toggling the chatflow to “Active.” Monitor conversations in HubSpot’s Conversations inbox, where every chatbot interaction is stored as a contact record with full history.
Method 3: How to Build an AI Chatbot for Free Using Botpress
Best for: More advanced users who want a fully customizable AI chatbot
Free plan: Unlimited messages, 5 bots
Time to deploy: 1 to 2 hours
Botpress is the most powerful free option for how to build an AI chatbot for free — it provides a full visual conversation designer, integration with OpenAI’s GPT models, and advanced AI capabilities on a genuinely free plan.
Step 1: Create Your Botpress Account
Go to botpress.com and sign up free. No credit card required. The free plan includes 5 bots and unlimited monthly conversations.
Step 2: Create a New Bot
In your Botpress workspace, click “Create bot”:
- Select “Start from scratch” for a custom build
- Or choose a template (Customer Support, Lead Generation, FAQ Bot)
- Name your bot and choose your primary language
Step 3: Design Conversation Flows
Botpress uses a visual node-based editor:
- Text nodes: Bot says something to the user
- Capture nodes: Collects user input (name, email, question)
- Condition nodes: Routes conversation based on user responses
- AI nodes: Uses GPT to understand and respond to open questions
Building a basic FAQ bot:
- Add a Text node: Welcome message
- Add a Choice node: “What can I help you with?” with button options
- For each option, add a Text node with the relevant information

Step 4: Add AI Knowledge Base
Go to your bot’s Knowledge Base section:
- Upload PDF documents (your FAQ, product catalog, service guides)
- Paste text content (your website FAQ page)
- Add URLs (Botpress crawls your website automatically)
Once your knowledge base is populated, the AI answers questions about your business using this content — handling questions outside your predefined flows naturally.
Step 5: Publish and Deploy
Go to Publish → Publish to Web:
- Copy the embed code or shareable link
- Embed in your website using the provided JavaScript snippet
- Or share the standalone chatbot URL directly
Essential AI Chatbot Content Every Business Needs
Regardless of which platform you use, your chatbot needs these core content pieces to be effective:
Must-Have FAQ Entries:
- What does your business do / what services do you offer?
- What are your prices or pricing ranges?
- What are your business hours?
- Where are you located / do you serve my area?
- How do I contact you / talk to a human?
- How long does it take to [deliver/complete/respond]?
- What is your return/cancellation/refund policy?
- Do you offer [common question specific to your industry]?
- How do I get started / place an order / book an appointment?
- What makes you different from competitors?
Must-Have Conversation Flows:
- Welcome and initial routing
- Lead capture (name + email + question)
- Appointment/call booking
- Human handoff (for complex questions)
- After-hours message with expected response time
Testing Your Free AI Chatbot Before Launch
Before sending real visitors to your chatbot, test it thoroughly:
Test these scenarios:
- Ask every FAQ question you added — does the AI answer correctly?
- Try spelling mistakes and informal phrasing — does it still understand?
- Try questions outside your FAQ — does it handle them gracefully?
- Go through every conversation flow completely
- Test on mobile — does the chat widget display correctly on small screens?
- Test in different browsers (Chrome, Safari, Firefox)
Red flags to fix before launch:
- AI gives incorrect information about your business
- Any flow leads to a dead end with no next step
- The welcome message does not appear on page load
- Mobile display is broken or overlapping content
