Create Your Chatbase Account
Sign up for Chatbase and understand the dashboard
📋 Detailed Instructions
Step 1: Go to Chatbase.co
Open your web browser (Chrome, Firefox, Safari, etc.) and type 'chatbase.co' in the address bar. Press Enter.
💡 Tip: Make sure you're on the official Chatbase website - look for the green lock icon in your browser's address bar.
Step 2: Click 'Get Started for Free'
Look for a blue or prominent button that says 'Get Started for Free' or 'Sign Up'. It's usually in the top right corner or center of the page.
💡 Tip: If you don't see this button, try scrolling down or refreshing the page.
Step 3: Choose your signup method
You can sign up with Google (recommended for beginners) or with your email address. Click 'Continue with Google' if you have a Gmail account.
💡 Tip: Using Google signup is faster and you won't need to remember another password.
Step 4: Complete your profile
Fill in your name, company name (can be your personal name), and select your use case as 'Customer Support'.
💡 Tip: Be honest about your company size - this helps Chatbase recommend the right features.
Step 5: Verify your email
Check your email inbox for a verification email from Chatbase. Click the verification link inside the email.
💡 Tip: Check your spam folder if you don't see the email within 5 minutes.
Step 6: Explore the dashboard
Once logged in, you'll see the main dashboard. Take a moment to look around - you'll see options like 'Create Chatbot', 'Analytics', and 'Settings'.
💡 Tip: Don't worry about understanding everything now - we'll go through each section step by step.

❌ Problem: Can't find the signup button

❌ Problem: Google signup not working
✅ Solution: Make sure you're logged into your Google account first, then try again. Or use email signup instead.
❌ Problem: Verification email not received

Get Your OpenAI API Key
Set up OpenAI account and get API access for ChatGPT
📋 Detailed Instructions
Step 1: Go to OpenAI Platform
Open a new browser tab and go to 'platform.openai.com'. This is different from the regular ChatGPT website.
💡 Tip: Make sure you're on 'platform.openai.com' not 'chat.openai.com' - the platform is for developers.
Step 2: Create OpenAI account
Click 'Sign up' and create an account using your email or Google account. You'll need to verify your phone number.
💡 Tip: Use the same email you used for Chatbase to keep things organized.
Step 3: Add payment method
Go to 'Billing' in the left sidebar and add a credit card. OpenAI requires a payment method even for small usage.
💡 Tip: Don't worry - typical usage for a small business chatbot costs $5-20/month. You can set spending limits.
Step 4: Set spending limits
In Billing settings, set a monthly spending limit (recommend starting with $20) to avoid unexpected charges.
💡 Tip: You can always increase this later. It's better to start conservative.
Step 5: Create API key
Go to 'API Keys' in the left sidebar, click 'Create new secret key', give it a name like 'Chatbot Key'.
💡 Tip: Copy this key immediately and save it somewhere safe - you won't be able to see it again!
Step 6: Save your API key securely
Copy the API key (starts with 'sk-') and paste it into a secure note app or password manager. Never share this key.
💡 Tip: Treat this like a password - anyone with this key can use your OpenAI account and you'll be charged for their usage.
⚙️ Configuration Details
// Your OpenAI API Key will look like this:
sk-proj-abcd1234efgh5678ijkl9012mnop3456qrst7890uvwx
// Important Security Notes:
✅ DO: Save in password manager
✅ DO: Set spending limits
✅ DO: Monitor usage regularly
❌ DON'T: Share with anyone
❌ DON'T: Put in public code
❌ DON'T: Email or text the key
// Typical Costs:
- 1,000 customer messages: ~$2-5
- 10,000 customer messages: ~$20-50
- Depends on message length and complexity🔧 Common Issues & Solutions
❌ Problem: Phone verification not working
✅ Solution: Try a different phone number or contact OpenAI support. Some VoIP numbers don't work.
❌ Problem: Credit card declined
✅ Solution: Contact your bank - they sometimes block AI service payments. Or try a different card.
❌ Problem: Can't see API key after creation
✅ Solution: You can only see the key once. Create a new one if you lost it, and delete the old one for security.
Create Your First Chatbot
Build and configure your AI customer support assistant
📋 Detailed Instructions
Step 1: Start creating your chatbot
In your Chatbase dashboard, click the big 'Create Chatbot' button or the '+' icon if you see it.
💡 Tip: If you don't see this button, make sure you're on the main dashboard page.
Step 2: Choose your data source
You'll see options like 'Website', 'Files', 'Text', or 'Q&A'. For customer support, choose 'Files' or 'Text' to start.
💡 Tip: You can always add more data sources later. Start simple with one type.
Step 3: Upload your knowledge base
If you have FAQs, product manuals, or support docs, upload them as PDF or text files. If not, you can type common questions and answers directly.
💡 Tip: Start with 10-20 common customer questions and answers. You can expand this later.
Step 4: Name your chatbot
Give your chatbot a friendly name like 'Support Assistant', 'Help Bot', or your company name + 'Assistant'.
💡 Tip: Choose a name that customers will trust and that reflects your brand.
Step 5: Set the personality
In the settings, describe how you want your chatbot to behave. Example: 'Friendly, helpful, professional customer support agent for [your company]'.
💡 Tip: Be specific about tone. Say 'polite and patient' if you want a calm bot, or 'enthusiastic and energetic' for a more upbeat one.
Step 6: Configure response settings
Set response length (recommend 'Medium'), creativity level (recommend 'Balanced'), and language (your preferred language).
💡 Tip: Start with balanced settings - you can fine-tune these later based on customer feedback.
⚙️ Configuration Details
// Example Chatbot Configuration:
{
"name": "SupportBot",
"personality": "Friendly and professional customer support agent for [Your Company]. Always helpful, patient, and tries to solve problems step-by-step.",
"response_length": "medium",
"creativity": "balanced",
"language": "English",
"fallback_message": "I'm not sure about that. Let me connect you with a human agent who can help better."
}
// Sample Training Data Format:
Q: What are your business hours?
A: We're open Monday-Friday 9 AM to 6 PM EST, and Saturday 10 AM to 4 PM EST. We're closed on Sundays.
Q: How do I return a product?
A: You can return any product within 30 days. Go to our Returns page, enter your order number, and print the prepaid shipping label.
Q: Do you offer refunds?
A: Yes! We offer full refunds within 30 days of purchase. Refunds are processed within 3-5 business days after we receive the returned item.🔧 Common Issues & Solutions
❌ Problem: Upload failed
✅ Solution: Check file size (must be under 10MB) and format (PDF, DOC, TXT only). Try converting to PDF if other formats don't work.
❌ Problem: Chatbot gives wrong answers
✅ Solution: Your training data might be unclear. Rewrite questions and answers more clearly, and add more examples.
❌ Problem: Responses too long/short
✅ Solution: Adjust the 'Response Length' setting in chatbot configuration. Also update your personality prompt to specify desired length.
Connect OpenAI to Your Chatbot
Link your OpenAI API key to power your chatbot with GPT
📋 Detailed Instructions
Step 1: Go to chatbot settings
Click on your newly created chatbot, then look for a 'Settings' or 'Configuration' tab. This is where you'll add your API key.
💡 Tip: The settings icon usually looks like a gear or cog wheel.
Step 2: Find the AI Model section
Look for a section called 'AI Model', 'OpenAI Integration', or 'API Settings'. This is where you'll paste your API key.
💡 Tip: If you can't find this section, look for 'Advanced Settings' or 'Integrations'.
Step 3: Enter your OpenAI API key
Paste the API key you saved earlier (starts with 'sk-') into the API key field. Make sure there are no extra spaces.
💡 Tip: Double-check the key - one wrong character and it won't work. Copy-paste is safer than typing.
Step 4: Select GPT model
Choose 'GPT-4' for best quality or 'GPT-3.5-turbo' for faster/cheaper responses. GPT-4 is recommended for customer support.
💡 Tip: GPT-4 costs more but gives much better customer service responses. Start with GPT-4 and switch if costs get too high.
Step 5: Set temperature/creativity
Set creativity to 0.3-0.5 for customer support (you want consistent, helpful answers, not creative ones).
💡 Tip: Lower numbers = more consistent responses. Higher numbers = more creative but potentially inconsistent responses.
Step 6: Test the connection
Look for a 'Test' button or send a test message to your chatbot. Ask it something like 'What are your business hours?'
💡 Tip: If the test fails, double-check your API key and make sure you have credits in your OpenAI account.
⚙️ Configuration Details
// Recommended OpenAI Settings for Customer Support:
{
"model": "gpt-4",
"temperature": 0.3,
"max_tokens": 500,
"top_p": 1,
"frequency_penalty": 0,
"presence_penalty": 0
}
// What these settings mean:
- model: GPT-4 for best quality, GPT-3.5-turbo for speed/cost
- temperature: 0.3 = consistent answers, 0.8 = creative answers
- max_tokens: 500 = about 375 words maximum response
- top_p: 1 = use full vocabulary
- frequency_penalty: 0 = don't avoid repeating words
- presence_penalty: 0 = don't avoid topics
// Test Messages to Try:
1. "What are your business hours?"
2. "How do I return a product?"
3. "I need help with my order"
4. "Do you offer technical support?"🔧 Common Issues & Solutions
❌ Problem: API key invalid error
✅ Solution: Check that you copied the full key including 'sk-' prefix. Make sure there are no spaces. Try creating a new API key.
❌ Problem: Insufficient credits error
✅ Solution: Add more money to your OpenAI account. Go to platform.openai.com > Billing and add funds.
❌ Problem: Connection timeout
✅ Solution: This usually means OpenAI servers are busy. Wait a few minutes and try again.
Train Your Chatbot with Customer Data
Add your specific business information and common questions
📋 Detailed Instructions
Step 1: Gather your customer support materials
Collect your FAQs, product manuals, return policies, shipping info, and any other documents customers ask about.
💡 Tip: Start with your most common customer questions. Check your email support history for frequent topics.
Step 2: Format your training data
Create clear question-and-answer pairs. Each should be specific and complete. Avoid vague or incomplete answers.
💡 Tip: Write answers as if you're talking to a customer directly. Use your brand's tone and voice.
Step 3: Add company-specific information
Include your business hours, contact info, return policy, shipping times, product details, and any unique policies.
💡 Tip: Be very specific about details like 'within 3-5 business days' rather than 'soon' or 'quickly'.
Step 4: Upload documents to chatbot
In Chatbase, go to your chatbot settings and look for 'Knowledge Base' or 'Training Data'. Upload your formatted documents.
💡 Tip: Upload one document at a time and test after each upload to make sure the bot learned correctly.
Step 5: Test with real scenarios
Ask your chatbot the same questions real customers ask. Test edge cases and difficult questions.
💡 Tip: Try to 'break' your chatbot with tricky questions. This helps you find gaps in your training data.
Step 6: Refine and improve
When the chatbot gives wrong or incomplete answers, add more training data or clarify existing answers.
💡 Tip: This is an ongoing process. Plan to update your chatbot's knowledge base monthly.

Customize Chatbot Appearance
Make your chatbot match your brand and website design
📋 Detailed Instructions
Step 1: Access appearance settings
In your Chatbase dashboard, go to your chatbot and look for 'Appearance', 'Customize', or 'Branding' settings.
💡 Tip: This is usually in the main chatbot settings or under an 'Integrations' tab.
Step 2: Upload your logo
Upload your company logo (PNG or JPG, recommended size: 100x100 pixels). This will appear in the chat header.
💡 Tip: Use a square logo if possible. If your logo is rectangular, it might get cropped.
Step 3: Set brand colors
Choose colors that match your website. Set the primary color (for buttons and headers) and secondary color (for accents).
💡 Tip: Use your website's exact color codes (hex codes like #FF5733) for perfect brand matching.
Step 4: Customize the welcome message
Write a friendly greeting that introduces your chatbot. Example: 'Hi! I'm here to help with any questions about [your company]. How can I assist you today?'
💡 Tip: Keep it short but welcoming. Mention what the bot can help with to set expectations.
Step 5: Set up suggested questions
Add 3-4 buttons with common questions like 'Business Hours', 'Return Policy', 'Track My Order', 'Contact Support'.
💡 Tip: Use your most frequent customer questions. This helps users get started quickly.
Step 6: Configure chat window settings
Set the chat window size, position (bottom right is standard), and whether it starts open or closed.
💡 Tip: Most users expect the chat in the bottom right corner. Starting closed is less intrusive.
⚙️ Configuration Details
// Brand Customization Checklist:
✅ Logo uploaded (100x100px recommended)
✅ Primary color matches website
✅ Secondary color complements primary
✅ Welcome message written
✅ 3-4 suggested questions added

✅ Solution: Upload a higher resolution image (at least 200x200px) and make sure it's a PNG with transparent background.
❌ Problem: Colors don't match website
✅ Solution: Use a color picker tool to get exact hex codes from your website. Many browsers have built-in color picker tools.
❌ Problem: Welcome message too long
✅ Solution: Keep it under 100 words. Focus on what the bot can help with rather than company history.
Embed Chatbot on Your Website
Add the chatbot to your website with a simple code snippet
📋 Detailed Instructions
Step 1: Get your embed code
In Chatbase, go to your chatbot settings and look for 'Embed' or 'Integration'. You'll see a code snippet that looks like HTML.
💡 Tip: This code is unique to your chatbot. Don't share it publicly as others could use your chatbot.
Step 2: Copy the embed code
Click the 'Copy' button next to the embed code, or select all the text and copy it (Ctrl+C on Windows, Cmd+C on Mac).
💡 Tip: The code will look like <script> tags with some JavaScript. This is normal and safe.
Step 3: Access your website editor
Log into your website platform (WordPress, Shopify, Wix, Squarespace, etc.) and go to the page editor or theme customizer.
💡 Tip: If you're not sure how to edit your website, contact your web developer or check your platform's help documentation.
Step 4: Find the right place to add code
Look for 'Custom HTML', 'Code Injection', 'Footer Scripts', or 'Before </body> tag' in your website settings.
💡 Tip: The exact location varies by platform. Adding to the footer or before </body> tag works for most sites.
Step 5: Paste the embed code
Paste the Chatbase embed code into the HTML/code section. Make sure you don't accidentally delete any existing code.
💡 Tip: Paste it on a new line, separate from other code. If you're unsure, ask a developer for help.
Step 6: Save and test
Save your changes and visit your website. You should see the chat widget appear (usually in the bottom right corner).
💡 Tip: If you don't see it immediately, try refreshing the page or clearing your browser cache.

Test and Launch Your Chatbot
Thoroughly test your chatbot and prepare for customer interactions
📋 Detailed Instructions
Step 1: Test basic functionality
Visit your website and test the chatbot with simple questions like 'What are your hours?' and 'How do I contact you?'
💡 Tip: Test from different devices (phone, tablet, computer) to make sure it works everywhere.
Step 2: Test complex scenarios
Try asking difficult questions, questions with typos, and questions outside your business scope to see how the bot handles them.
💡 Tip: The bot should gracefully handle questions it can't answer by offering to connect with a human agent.
Step 3: Test the handoff to humans
Make sure customers can easily reach a human when needed. Test phrases like 'I want to talk to a person' or 'Connect me to support'.
💡 Tip: Set up clear instructions for how customers can reach human support when the bot can't help.
Step 4: Set up analytics tracking
In Chatbase, explore the analytics section to understand what metrics you can track (conversations, satisfaction, common questions).
💡 Tip: Pay attention to unanswered questions - these show you what training data to add next.
Step 5: Create a monitoring routine
Plan to check your chatbot weekly for new questions, errors, or customer feedback. Set up email notifications if available.
