AI Chatbot for Astro Sites
You chose a framework that ships almost no JavaScript. A support widget that undoes that is not an option, which is why this one is a single deferred script that loads after the page is already usable.

See It In Action
For content sites, docs and marketing pages built with Astro
Respects the Zero-JavaScript Default
Astro ships static HTML by design, and every kilobyte of client JavaScript is a deliberate decision. The assistant is one deferred script under 50KB that loads after your content, so your performance profile stays intact.
One Tag in Your Layout
No integration to install, no island to hydrate, no framework component. A script tag in your base layout applies to every page Astro builds.
Answers Documentation Questions
Readers arrive at docs with a specific problem and rarely find the exact page. The assistant answers from your published content, which is faster than any search box.
Survives a Content Rebuild
Because it reads your published pages rather than your content collections, restructuring markdown or changing your content schema does not affect it.
Thirty-Six Languages
Detected per visitor, with no i18n routing work on your side.

Frequently Asked Questions
What Astro developers ask first
What an AI Assistant Adds to a Static Site
Performance Discipline Rules Out Most Widgets
Teams that choose Astro have usually been burned by JavaScript bloat and are deliberate about what runs in the browser. Most support widgets fail that test immediately: heavy bundles, render-blocking loads, layout shift.
A single deferred script under 50KB is a different proposition. It arrives after the page is usable and does not compete with your content for the main thread, which makes it defensible in a codebase where weight is reviewed.
Docs Are Where Search Fails Hardest
Documentation search only works for readers who already know the vocabulary. Everyone else searches for the problem in their own words, gets nothing useful, and leaves with the impression that the docs are incomplete.
Answering conversationally from the same pages fixes the access problem rather than the content. Readers describe their situation and get pointed at the right page, which is what they wanted from search.
Reading the Built Site Beats Reading the Source
Integrations that parse content collections or markdown frontmatter break whenever the content structure changes, and content structure changes constantly on active sites.
Crawling the rendered output avoids that entirely. Whatever your source looks like, the published pages are the contract with your readers, and that is what the assistant reads.
Static Sites Still Get Sales Questions
Marketing sites built with Astro are often the front door to a product, and visitors ask commercial questions the page deliberately leaves out: pricing edge cases, integrations, whether it fits their scale.
Answering those without adding another section to the page keeps the page fast and focused while still converting the visitor who needed one more fact.
Nothing to Maintain in the Repo
Every dependency added to a static site is a future upgrade, an audit item and a potential build failure. Keeping the repository clean is part of why the stack was chosen.
A script tag introduces none of that. Configuration lives outside the project, and removing it is deleting one line from a layout.
