What it handles

The questions your customers ask every day

They come right before the purchase, often in the evening. Without a quick answer, the cart stays empty. The chatbot answers them with your store's own information.

When will it arrive?How do I return an item?Which size should I pick?Can I pay with Afterpay?Do you offer 2-day shipping?My promo code doesn't work
Where is my order?Do you ship to Canada?What fabric is it?Do you offer gift wrapping?When is it back in stock?Do you sell wholesale?

Setup

Simple setup on Express

Most Express apps render every page through one shared layout or one footer partial. You add the script tag there once, deploy, and the chat shows on every page. Four steps, five minutes.

Sign up and copy your code

Create your Asyntai account, add your site's address and copy your code from the dashboard. The AI starts reading your pages right away.

Open your layout

Open the shared layout of your views, for example views/layout.ejs, or the footer partial that every view includes, for example views/partials/footer.ejs.

Paste before </body>

Paste the script tag just before the closing </body> tag. In Pug, add it as a script line at the end of the body block of your layout.

Deploy, and you're live

Deploy as usual and restart your Node.js process, for example with PM2. The chat bubble appears in the corner of every page and already answers your users.

If each view includes a footer partial, such as views/partials/footer.ejs, add the tag there. Pages that use their own layout, or static HTML files in public/, need the tag too.

Why Asyntai

What Express sites gain

Start free with 50 messages, then grow with your store.

01

Fewer abandoned carts

A customer with a doubt right before paying gets an answer straight away. A question about shipping costs no longer makes them leave the store.

02

Fewer repetitive requests

Shipping, tracking, returns and sizes get an automatic answer from your own pages. You only handle the requests that really need you.

03

More sales, same traffic

You already pay to bring in visitors with Google Ads, Meta or marketplaces. The chatbot helps them find the right product and order.

FAQ

Frequently asked questions

Everything you need to know to add an AI chatbot to your Express store.

Do I need an npm package?

No. One script tag in your layout loads the chat on every page. There is no npm package, no require or import and no dependency to update when you upgrade Express or Node.js.

Do I need a route, middleware or an API key?

No. The chat runs on Asyntai servers and talks to them from the browser. You do not add routes, middleware or workers, and the only value in your code is your public site ID.

Will it slow down my Express app?

No. The script loads asynchronously, after the page is shown. It is not part of your bundle and adds nothing to your server response time.

How does the chatbot learn my content?

When you add your site's address, the AI reads your published pages: products, docs, blog posts and policies. You can upload documents and add your own instructions. After you publish new pages, run a new crawl from the dashboard.

Does it work with Pug and Handlebars?

Yes. The tag is plain HTML. In Handlebars, add it to the main layout, for example views/layouts/main.handlebars. In Pug, add a script line to the layout that your views extend.

Can I show it only to some users or on some pages?

Yes. Wrap the tag in a condition of your view engine, for example on a user value that you pass to the view, or put it in a partial that only some views include.

Does it answer visitors who speak another language?

Yes. The chatbot detects the visitor's language and replies in it, even if your Express site is only in English.

Can I use it on several sites?

Yes. Each site has its own setup and knowledge base. The Free plan covers 1 site, Starter 2, Standard 3 and Pro up to 20 sites.

Guide

How an AI chatbot helps Express apps

Your app has the answers, somewhere

Express is a popular, minimal web framework for Node.js. Teams use it for SaaS products, online stores, portals, dashboards and internal tools. Users still get stuck: how does this feature work, what does my plan include, who do I contact.

An AI chatbot answers them in your app. It reads your published pages, docs and policies, then replies in plain English, in the tone you choose. Users get an immediate answer, and your team gets fewer support tickets about things that are already documented.

Answering the questions that block an order

Most questions arrive just before the purchase: shipping times, returns if the size is wrong, 2-day shipping, paying in installments. If the shopper can't find the answer in a few seconds, they close the tab.

The chatbot answers from your shipping, returns and terms pages. It reminds them of your return window, the carriers you use and your free-shipping threshold. The shopper feels reassured and completes the order.

A salesperson who knows every product

In a store, a salesperson helps with the choice. Online, the shopper is alone with your product pages. The chatbot takes that role: it compares two models, explains the difference between materials, recommends a size or suggests a matching item from your catalog.

Because it only answers from your content, it never recommends products you don't sell and never makes up specs. The richer your product pages, the more precise the answers.

Useful insights for your next campaigns

Every conversation is saved and searchable. Over the weeks, you see which products interest people most, the objections that keep coming up and the information that is missing.

If many shoppers ask whether a product comes in another color, you know what to add to your catalog. If shipping costs keep coming up, you can show them more clearly. The chatbot becomes both a customer service tool and a source of insight to grow your store.
