Which Replit deployment types does the chatbot work with?

All of them. The widget is a plain script tag in your HTML, so it runs the same on a Static Deployment, an Autoscale Deployment, a Reserved VM Deployment, your development preview, and any custom domain you connect.

Do I need to redeploy the Replit app after adding the snippet?

Yes, once. Replit serves your published app from a snapshot of your files, so the chat bubble appears on the live replit.app URL after you publish again. Later changes to the chatbot itself are made in the Asyntai dashboard and take effect immediately, with no redeploy.

How does the chatbot know what my Replit app does?

It reads your published pages automatically, and you can upload documents, add question and answer pairs, and write custom instructions in the dashboard. It answers using your own content rather than generic AI knowledge, and you decide what it should refuse to discuss.

Is there a free plan for a Replit side project?

Yes. The free plan includes 100 messages per month, which is enough to see what your first real users ask before you pay for anything. Paid plans raise the limit and add more features.

Works on any published Replit app

AI Chatbot for Replit — because your app has users now, not just visitors

Q: How do I add a chatbot to a published Replit app?

Sign up at Asyntai and copy your snippet from the dashboard. In the Replit workspace, open the file that holds your page shell and paste the snippet just before the closing head tag: index.html at the project root for a static or Vite app, or the root layout file for a Next.js app. You can also paste the snippet into the Agent chat and ask it to add the script to every page. Then press Publish again so the change reaches your live deployment.

Replit does not stop at a landing page. It gives you a database, logins, a deploy button, and a real URL, so the thing you built has people inside it doing things. Asyntai adds the missing piece: a chatbot on your published app that answers those people using your own content, hands you their questions, and never sleeps through a timezone. One script tag, one republish.

Why Replit apps outgrow their founder's inbox

A brochure site gets asked three things: price, location, hours. A Replit app gets asked everything else. People sign up, hit a limit, lose a password, misread a button, want to know whether their data is safe, and ask if the thing they just paid for can also do the one job they need. That is not marketing traffic. That is a product with users, and users generate support.

The uncomfortable part is timing. Replit is built so one person can ship something serious in a week, which means the support load arrives long before the second hire does. There is no shared inbox, no help centre, no rota. There is you, and a notification at two in the morning from somebody eight timezones away who is stuck on step one.

You automated the deploy. Automate the part that wakes you up.

A chatbot on the app itself takes the first pass. It answers the repeat questions instantly, in the visitor's own language, at the exact moment they are confused, which is the only moment the answer is worth anything. What it cannot answer, it captures, so nothing quietly turns into a churned user. And the transcript log becomes the clearest signal you have about which part of your product is unclear.

How to add a chatbot to Replit in three steps

Create your chatbot. Sign up free at Asyntai, point it at your published Replit URL so it learns your pages, and copy the snippet from your dashboard.

Paste the snippet into your page shell. In the Replit workspace, open index.html at the project root for a static or Vite app, or your root layout file for a framework app, and paste the snippet just before </head>. Prefer to delegate? Paste it into the Agent chat instead and ask.

Publish again. Press the publish icon in the Project Editor. Replit snapshots your files and pushes them live, so the chat bubble appears on your .replit.app address or your custom domain.

Add this script tag to the <head> of the app shell so it loads on every page, then leave the rest of the code alone: [paste your Asyntai snippet]

There is no marketplace listing, no OAuth screen, and no plugin to keep updated, because you own the files. If you can edit HTML in the Replit editor, the install is done in the time it takes the deploy to finish.

What your Replit chatbot handles

Answers using your own content

It reads your published pages and any documents you upload, then answers from those. Anything outside them gets an honest fallback, not a confident guess.

Catches the leads you would miss

When a visitor needs a human or shows real intent, the chatbot takes their email and the whole conversation lands in your dashboard.

Speaks to a global user base

Replit apps get traffic from everywhere. The chatbot detects the visitor's language and replies in it, across 30+ languages, with nothing to configure.

Behaves the way you tell it to

Colours, position, greeting, and tone are set in the dashboard. Custom instructions decide what it explains, what it escalates, and what it declines.

Questions Replit builders ask about the chatbot

How do I add a chatbot to a published Replit app?

Copy your snippet, paste it before </head> in index.html or your root layout file, and publish again. Or paste the snippet into the Agent chat and ask it to add the script to every page.

Which deployment types does it work with?

All of them. It is a plain script tag, so it behaves identically on Static, Autoscale, and Reserved VM deployments, on the development preview, and on any custom domain.

Once. Replit serves a snapshot of your files, so publish again to push the change live. After that, chatbot changes are made in the dashboard and apply instantly with no redeploy.

How does it learn what my app does?

It crawls your published pages, and you fill the gaps with uploaded documents, question and answer pairs, and custom instructions in the dashboard.

Is there a free plan?

Yes, 100 messages per month, free. Enough to learn what your first users are confused about. Higher limits and extra features are on pricing.
