AI Chatbot for Eleventy Sites

Eleventy stays out of your way, and so should anything you add to it. One line in your base layout, whichever template language you happen to be using, and the assistant answers from your published pages.

See It In Action

For blogs, docs and content sites built with Eleventy

AI assistant added to any Eleventy template language

Works With Whatever Templating You Chose

Nunjucks, Liquid, Handlebars, plain HTML — the tag is identical in all of them, because it is just HTML. No plugin API, no filter, no shortcode to register.

Adding the Asyntai tag to an Eleventy base layout

One Line in the Base Layout

Everything that inherits your base layout gets it, which on most Eleventy sites means everything. No per-template work and no data cascade involvement.

AI reading Eleventy build output

Reads the Built Site

It crawls the output rather than your source, so restructuring collections, renaming folders or switching template language changes nothing for it.

Chatbot answering a reader question

Answers What Readers Actually Ask

Blog and docs readers arrive with a specific question the article nearly answers. Handling that directly is faster than expecting them to read three more posts.

Chatbot answering readers in several languages

Thirty-Six Languages

Detected per visitor, without touching your i18n plugin or permalink structure.

Ask it anything - it is live on this page

Built for Eleventy Merchants

A layout edit that works in whichever templating you picked.

Template-Agnostic

It is HTML, so Nunjucks, Liquid or plain files all work the same.

Base Layout Coverage

Add once; every page inheriting the layout carries it.

Costs You Nothing at Build

The generator emits a tag; weight arrives later, in the reader’s browser.

Reads Output, Not Source

Collections and folder structures can change freely.

36 Languages

Chosen from the visitor’s message automatically.

No Invented Content

It answers from your pages and says when something is not covered.

Simple Eleventy Integration

One line in the base layout covers the site. No plugin and no config changes.

  1. 1

    Register and copy the tag

    Make an account, give it your site address so the pages can be indexed, then take the tag.

  2. 2

    Open your base layout

    Add the tag before the closing body tag in the layout your pages inherit.

  3. 3

    Run the build again

    The tag appears in the output. eleventy.config stays exactly as it is.

  4. 4

    Everything else is dashboard-side

    Register, rules, reference uploads and colours are all controlled outside the project.

Frequently Asked Questions

What Eleventy users ask first

How do I add it?
One HTML tag in your base layout before the closing body tag. It works identically in every template language Eleventy supports.
Is there an Eleventy plugin?
None needed. Because it is plain HTML there is no plugin API involvement and nothing to keep compatible with Eleventy versions.
Does it slow the build?
No. It is not part of the build at all; the browser fetches it at runtime.
Does it read my markdown source?
No, it reads the built pages. Reorganising collections or source folders has no effect on it.
Can I put it on only part of the site?
Yes. Use a different layout for the section you want it on, or add it to that layout only.
Does it work with pagination?
Yes. Paginated output is ordinary HTML as far as the assistant is concerned.
And performance?
A small deferred request, so nothing competes with your content for the main thread.
If we run past the allowance?
It pauses until the next cycle, or you move up a tier. Free carries a hundred conversations a month, Starter twenty-five hundred.
Several sites from one account?
Each is walled off with its own index and instructions. One on Free, two on Starter, three on Standard, twenty on Pro.

What an AI Assistant Adds to a Static Content Site

Simplicity Is the Whole Appeal

Eleventy attracts people who got tired of tooling. The configuration is small, the build is fast, and adding anything that reintroduces complexity defeats the purpose.

A single HTML tag is about as simple as an addition gets. No plugin, no build hook, no config export — and removal is deleting the line.

Readers Ask What the Post Nearly Answered

Content sites answer questions in general and get asked about specifics. The post explains an approach; the reader wants to know whether it applies to their version, their setup, their case.

Answering that in the moment keeps the reader on the page and shows you which articles need a paragraph adding.

Output Is the Contract

Static site sources get restructured constantly: new collections, renamed folders, a switch of template language. Tools that read source break on all of it.

Reading the built output avoids that entirely, because the pages you publish are the thing readers and crawlers both consume.

Build Speed Is a Feature

Part of why Eleventy is pleasant is that builds finish quickly. Anything added to the build makes the feedback loop worse, which is felt on every save.

Because the assistant is fetched at runtime, build time is untouched. The development experience stays exactly as it was.

Personal Sites Need Zero Maintenance

A blog maintained in spare time cannot carry tools that need attention. Anything requiring upkeep quietly stops working and stays broken.

There is nothing to maintain here: no plugin version, no config, no dependency. Behaviour changes happen in a dashboard.
