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

Setup with the Starlight plugin

Asyntai has a free Starlight plugin on npm. You add it to the plugins of Starlight, build the site, and the chat shows on every docs page. Four steps, five minutes.

Copy your widget ID

Sign in to Asyntai and open the Install page. Your widget ID is the data-asyntai-id value in the snippet. It starts with asyntai_.

Install the package

In your docs project folder, run npm install starlight-ai-chatbot.

Add the plugin

Open astro.config.mjs, import starlightAiChatbot and add it to the plugins array of Starlight with your widget ID.

Build, and you're live

Run npm run build and publish. The chat bubble appears in the corner of every docs page and already answers your readers.

A missing or wrong widgetId stops the build with a message that tells you how to fix it. Set enableInDevelopment to false to keep the chat off during astro dev.

Why Asyntai

What Starlight 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 Starlight store.

Do I need to override a Starlight component?

No. The plugin adds the chat to every page through the Starlight plugin system. You do not override Head, Footer or any other component.

Which versions does it support?

The plugin works with Starlight 0.30 and newer, on Node 18 or newer. It works with any Starlight theme and any static host.

Will it slow down my docs?

No. The chat script loads asynchronously, after the page is shown. It is not part of your Astro bundle.

How does the chatbot learn my docs?

Add the address of your docs site in the Asyntai dashboard. The AI reads your published pages and answers from the same pages that the chat sits on. You can also add documents and question and answer pairs.

Does it work with Starlight search?

Yes. Search finds pages, and the chatbot gives the answer in plain words, with a link to the page. Readers use the one that fits their question.

Can I use it on several docs sites?

Yes. Each docs site can have its own Asyntai site, knowledge base and tone. Use a different widget ID in the config of each site.

Does it answer readers who speak another language?

Yes. The chatbot detects the reader's language and replies in it, even if your docs are 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 Starlight docs

Good docs, still many questions

Starlight is the documentation theme for Astro. Open-source projects, developer tools and SaaS companies use it for fast, clean docs sites. Readers still ask the same things: how do I install it, why does this error appear, which option do I need.

An AI chatbot answers them on the page. It reads your docs, then replies in plain words, in the tone you choose, with a link to the page that has the details. Readers get an answer at once, and your team gets fewer issues and support emails.

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.
