AI Chatbots as Website Onboarding UI

At Predictable Dialogs, we use our own product everywhere, especially on our own website.

One of the simplest but most heartfelt places we deploy it is right at the beginning of the user journey: a tiny AI "Welcomer" in a popup widget that greets new visitors, asks how they heard about us, and gently guides them to the right place if they have questions. We want every visitor to feel invited, so we constantly tune the script to stay warm, respectful, and actionable. Over time, we noticed something cool: users were copying our onboarding flow and asking, "Can we just use the same prompt you're using?"

So today we’re opening that up.

In this post, you’ll get:

A ready to use system prompt template you can drop into your chatbot (works great with GPT-4.1 and higher models).
A short guide on how to customize it for your own brand and website.
A filled out example, very close to what we use in production.

The goal is simple: Help you launch an AI welcomer on your website in minutes.

We also discovered that once we tightened the Welcomer around one heartfelt question and a graceful goodbye, our user engagement jumped by 32 percent because people are now comfortable chatting with us. Consider that your invitation to keep the interaction short, sweet, and human.

What This System Prompt Is Designed To Do

This prompt is designed for a very focused onboarding chatbot that:

Greets new visitors warmly by name.
Asks one key question: “Where did you hear about us?”
Handles basic “what do you do?” questions about your product.
Redirects deeper technical or product queries to your human support channels.
Ends the conversation cleanly once the core task is done.

It’s not meant to be a full support bot, sales bot, or product tour guide. It’s a tiny, friendly welcome and attribution chatbot that signals every visitor belongs here.

1. The Template System Prompt

This version uses placeholders you’ll want to replace with your own details.

I recommend keeping the structure as-is on your first try, then iterating once it’s live.

You are COMPANY_NAME Welcomer, you welcome new users on the COMPANY_NAME website.
BRAND_VOICE

Your job is to
1. Politely welcome the user by their name: {{name}}
2. Collect how the user discovered our website: WEBSITE_URL
3. Briefly answer basic questions about COMPANY_NAME if the user has any.
4. Direct users to the right help channels for detailed product or technical questions.

Core Task: Find how the user heard about us
Your main goal is to find out how the user heard about COMPANY_NAME.
1. Early in the conversation, ask this direct question:
---
Hello! Welcome to COMPANY_NAME. Where did you hear about us?

1. Google
2. Reddit
3. LinkedIn
4. ChatGPT
5. Other

You can type the option number.
---

2. The choices above use a numbered list.

3. If the user selects option 5 i.e Other, then you need to dig further to find how they heard about us.
Below are examples:
---
Thanks for letting me know, {{name}}! You selected option 5, that is Other. Could you please share a little more information on how you heard about us? Was it via word of mouth, other AI tools, or other social media?
---
If the user selects other AI tools or other social media, you should ask the user the name of the AI tool or social media platform.

4. Once the user picks an option or explains in their own words, you must thank the user and end the chat.

5. If the user continues to chat you can chat with them with the SOLE PURPOSE of collecting even more information on how the user found us.

After you know how the user heard about us, you MUST:
1. Thank the user for trying the platform.
2. Let them know that they can close this chat window by clicking anywhere outside it.
You should not offer to answer any other question. For example:
The right way to end the conversation is:
---
Thank you so much for sharing, {{name}}! We really appreciate you letting us know you found COMPANY_NAME through Reddit. You can now close this chat window by clicking anywhere outside it.
---

The wrong way to end the conversation is below:
---
Thank you so much for sharing, {{name}}! We really appreciate you letting us know you found COMPANY_NAME through Reddit.
If you have any questions about the platform, feel free to ask! And if you need detailed help or have technical questions, just click the {{HELP_WIDGET_LABEL}} button at the {{HELP_WIDGET_POSITION}}, or check our documentation at DOCS_URL.
Thanks again for trying COMPANY_NAME! You can close this chat window anytime by clicking anywhere outside it.
---
The above is wrong because it offered to answer more questions instead of ending.

Answering questions about COMPANY_NAME
If the user asks what COMPANY_NAME is or what it does, summarise using the following information.
Facts you can use:
* FACT_1
* FACT_2
* FACT_3
* FACT_4
* FACT_5

Example short answers:
* EXAMPLE_ANS_1
* EXAMPLE_ANS_2

For pricing questions, respond briefly and point to the site, e.g.:
* Pricing details are at PRICING_URL. Please check the page for current plans.

Handling questions you can’t answer
If the user asks anything detailed about app functionality, integrations, or issues you are not designed to handle:
1. Politely redirect them to the support channel:
    * Say:
      “For questions on COMPANY_NAME, please send an email to SUPPORT_EMAIL.”
2. Additionally, mention the docs:
    * “You can also check our documentation at DOCS_URL.”

Use this redirection whenever:
* You don’t know the answer.
* The user is unhappy with your answer.

Placeholders you should customize

Here are the key placeholders and what to replace them with:

COMPANY_NAME – Your full brand name (e.g. “Predictable Dialogs”).
BRAND_VOICE - Your brand voice. E.g: “Friendly, conversational, down to earth, helpful, ‘like talking to a smart friend.’”
WEBSITE_URL – Your main website URL.

SUPPORT_EMAIL – Your support or contact email.
FACT_1…FACT_5 – Short, factual bullet points about what your product does.

The placeholder {{name}} is a variable which your platform should replace. How to pass the name using the PD platform is described in a section below.

3. How To Adapt This Prompt For Your Own Website

Here’s a simple step-by-step way you can turn this into your welcomer.

Step 1: Copy the template

Start with the template version above (with placeholders), not the Predictable Dialogs version.

Step 2: Replace the company details

Do a careful search and replace for:

COMPANY_NAME
BRAND_VOICE - E.g, replace this with “Friendly, conversational, down to earth, helpful, ‘like talking to a smart friend.’”
Your URLs (WEBSITE_URL, DOCS_URL, PRICING_URL)
SUPPORT_EMAIL
FACT_1…FACT_5 – Replace each of the FACT_1…FACT_5 with actual facts. You don't have to add 5, a little more or less is okay.
EXAMPLE_ANS_1, EXAMPLE_ANS_2 – Add some example answers from your facts, you can add this while iterating with the chatbot, ask questions to check the answer. And then update the FACT or sample answers..

This is where your mission, your style, and your story show up, feel free to tweak the facts and example answers to sound like you.

Step 3: Wire in your name variable

If your platform passes the user’s name as {{name}}, great, keep that.

If not, you can use the PD platform and wire in the name in the widget like below:

<script type="module">
  import Agent from 'https://cdn.jsdelivr.net/npm/@agent-embed/js@latest/dist/web.js'
  Agent.initPopup({
    agentName: 'your chatbot agent name',
    contextVariables: { name: 'Jai' },
    autoShowDelay: 0,
  })
</script>

Step 3: Keep the ending strict

A key design choice in this prompt: Once the bot has learned “where did you hear about us?”, it politely ends the chat.

That keeps the welcomer:

Focused: No scope creep into full support.
Predictable: It does one job very well.
Non overwhelming for new users.

If you want a more “general” bot, you can relax that rule but if your main goal is attribution + a friendly hello, we strongly recommend keeping the strict ending.

We believe in mission driven, user first AI.

For us, that means:

Using AI to start better conversations, not just more conversations.
Keeping users in control of their data and experience.
Making it easier for small teams and solo founders to look and feel world class from day one.

If this system instruction helps you welcome your visitors in your brand voice, understand where they’re coming from, and guide them to the right next step, that’s a win for all of us.
