Add an AI support chat widget to Replit

How VibeCS works on Replit

1. 1.Paste your site's address into the dashboard. VibeCS crawls your public pages and builds the bot from them. Nothing to upload, no training data.
2. 2.Ask it the questions your customers ask. Pick a tone: friendly or direct. Adjust the color to match your brand.
3. 3.Paste the snippet into the template that wraps every page, through Replit Agent. The chat bubble appears on your site and answers from your pages only.

Where to paste the snippet in Replit

1. 1.Open your app in Replit.
2. 2.In the Agent chat, type: "Add this script tag just before </body> in the HTML template that wraps every page:" and paste the VibeCS snippet after it.
3. 3.Check the Preview, then click Publish in the upper-right corner. If the app is already live, click Republish.

Any stack works. The Agent finds the template: it's the file that holds the <body> tag.

Add this script tag just before </body> in the HTML template that wraps every page:

The snippet is one line. The dashboard generates yours with your site's own id:

<script src="https://cs-vibe.com/widget/v1.js" data-site-id="your-site-id" data-persona="buddy"></script>

What the bot can answer

• Anything on your public pages: pricing, hours, policies, how-tos, product details, contact options.
• In your words. It answers from your content and doesn't invent policies you don't have.
• At any hour, on every page where the snippet runs, on phones and desktops.
• When it doesn't know, it says so and points the visitor to you. On Pro it offers to take their email.
• It re-reads your site every week, so updates to your pages reach the bot on their own.

Questions people ask before installing

Do I have to edit code?

No. Paste the snippet into the Agent chat with the sentence from the steps above and the Agent adds it to the file that wraps every page.

Does it work on the .replit.app address?

Yes. The widget runs on any address. Train the bot on the address visitors use, the .replit.app one or your own domain, and it reads the pages there.

Do I need a developer?

No. You paste one line of code into the template that wraps every page, through Replit Agent. If you'd rather not, the dashboard can email the exact steps and the snippet to whoever manages your Replit app.

What does it cost?

$8 a month for the base plan, $12 a month for Pro, which adds an inbox of every conversation, lead capture when the bot can't answer and a weekly digest, or $99 once for everything in Pro, guaranteed for at least a year. Agencies building client sites can cover up to 20 of them for $49 a month. You can test the bot on your site before paying.

Will it slow down my Replit app?

No. The widget is one small script that loads after your page, and the chat itself runs on our servers.

What happens when it doesn't know the answer?

It says so and points the visitor to you instead of guessing. On Pro it offers to take their email so you can follow up.
