Quick Start

Time estimate: ~8 minutes

​

Step 1: Create your account

1. Go to app.replybubble.com/signup
2. Enter your email and create a password
3. You’ll start with a 14-day Pro trial — no credit card required

​

Step 2: Connect your AI provider

Typical cost: A small business with 500 conversations/month spends $3–10/month on AI usage.

​

Get an OpenAI key (recommended for most users)

1. Go to platform.openai.com/api-keys and sign in (or create an account)
2. Click Create new secret key
3. Name it something like “ReplyBubble” and click Create
4. Copy the key — it starts with sk-proj-

​

Connect the key in ReplyBubble

1. In your dashboard, go to Settings > AI Provider
2. Select OpenAI as your provider
3. Paste your API key and click Save
4. Choose a model:
   • GPT-4o-mini — fast, affordable, great for most use cases
   • GPT-4o — smarter, better for complex topics, costs more

​

Step 3: Add your first knowledge base content

​

Quickest option: auto-crawl your website

1. Go to Knowledge Base > Sources
2. Enter your website URL
3. Click Crawl — ReplyBubble will index your pages automatically

​

Or add a document manually

1. Go to Knowledge Base > Documents
2. Click Add Document
3. Write or paste content (FAQ answers, product info, policies, etc.)
4. Click Save

Tip: Start with your most common customer questions. Even 5–10 well-written answers make a big difference.

​

Step 4: Install the widget on your site

<script src="https://app.replybubble.com/widget/replybubble.js"
        data-widget-id="YOUR_WIDGET_ID"
        async>
</script>

Platform-specific instructions

Step 5: Verify it works

1. Open your website in a new browser tab
2. You should see a chat bubble in the bottom-right corner
3. Click it and ask a question that your knowledge base can answer
4. The bot should respond with an accurate answer drawn from your content
