See It In Action

For product sites, docs and marketing apps built on Next.js

AI assistant added without an npm package

Nothing in Your Bundle

No npm package means no version to track, no peer dependency conflicts and nothing added to your client bundle at build time. The script loads at runtime from our CDN, which keeps your build output unchanged.

Adding the Asyntai script tag to a Next.js layout

One Tag in the Root Layout

Add it to the root layout and every route is covered, App Router or Pages Router alike. No provider to wrap, no client component boundary to think about.

AI working across rendering strategies

Works With Any Rendering Strategy

Static, server-rendered, streamed or incrementally regenerated — it makes no difference. The assistant reads your published pages and runs in the browser.

Chatbot answering product and documentation questions

Answers Product and Docs Questions

Pricing edge cases, integration questions, limits, migration paths. The things a landing page cannot cover and a search box answers badly.

Chatbot answering visitors in several languages

Thirty-Six Languages

Detected per visitor, with no changes to your i18n routing or middleware.

Ask it anything - it is live on this page

Built for Next.js Merchants

One script tag in the root layout. No SDK, no provider, no bundle impact.

No Package to Install

Nothing in package.json, so no upgrades, audits or peer dependency problems.

Router-Agnostic

App Router or Pages Router; a tag in the root layout covers both.

Rendering-Agnostic

Static, SSR, streaming and ISR all behave identically as far as the assistant is concerned.

Under 50KB, Deferred

Loads after your content, so Core Web Vitals are unaffected.

36 Languages

Detected per visitor without touching middleware or i18n config.

No Invented Answers

It answers from your published pages and states when something is not documented.

Simple Next.js Integration

One script tag in your root layout covers every route. Nothing is added to your dependencies.

  1. 1

    Sign up and copy your snippet

    Create your Asyntai account, add your site URL so the AI can read your published pages, then copy the snippet from your dashboard.

  2. 2

    Add the tag to your root layout

    Place it near the end of the body so it loads after your content. Next.js also provides a Script component if you prefer to use it.

  3. 3

    Deploy

    The assistant works on every route immediately, in production and in preview deployments.

  4. 4

    Configure from the dashboard

    Tone, rules, uploaded documents and appearance are managed outside your repository.

Frequently Asked Questions

What Next.js teams ask first

How do I add it to a Next.js app?
One script tag in your root layout, placed near the end of the body. You can use the framework’s Script component with an appropriate strategy if you prefer.
Is there an npm package?
No, deliberately. Nothing enters your dependency tree, so there is no version to track and no peer dependency risk.
Does it work with the App Router?
Yes, and with the Pages Router. A tag in the root layout covers every route in either case.
Will it affect Core Web Vitals?
No. It is under 50KB and loads after your content, so it does not block rendering or shift layout.
Does it interfere with server components?
No. It is browser-side only, so it has no interaction with your server component tree or data fetching.
Where does its knowledge come from?
Your published pages, crawled on demand, plus uploads for anything not published.
Can I scope it to certain routes?
Yes. Put the tag in a nested layout rather than the root one to limit it to a route segment.
What happens at the message limit?
Free includes 100 messages a month, Starter 2,500. At the limit it pauses until the next reset, or you upgrade instantly.
Can I use it across several projects?
Yes, each with its own knowledge base. Free covers 1, Starter 2, Standard 3, and Pro up to 20.

What an AI Assistant Adds to a Next.js Application

Dependencies Are Where Maintenance Cost Accumulates

Anyone maintaining a large Next.js app knows the pattern: a package added for a small feature becomes a version constraint, then a peer dependency conflict, then the reason an upgrade takes a week.

A runtime script sidesteps all of it. There is nothing in the lockfile, nothing to audit, and no chance of a third-party release breaking your build the day before a launch.

Marketing Routes Do the Selling

In most product companies the Next.js app contains both the application and the marketing site. Those marketing routes carry the acquisition load, and their conversion depends on answering objections the copy deliberately omits.

Handling those conversationally means the page stays focused while the visitor who needs one more fact gets it immediately, which is usually cheaper than another round of copy testing.

Docs Traffic Deserves Better Than Search

Developer documentation is read by people with a specific error or a specific goal, and they rarely search using the words your docs use. Search returns near-misses and they leave.

Answering from the same pages in the reader’s own phrasing converts that frustration into a resolved question, and shows you which pages people cannot find.

Browser-Side Only Keeps the Boundary Clean

Modern Next.js apps have a careful separation between server and client work. Anything that requires server-side integration, environment variables or middleware changes adds coupling for a feature that does not need it.

Keeping the assistant entirely in the browser means no environment configuration, no middleware, and no interaction with server components or caching.

Reversibility Is Worth More Than Convenience

A tool that can be removed in one commit is easy to trial. A tool with an SDK, a provider component and configuration spread across the codebase is not, so it never gets trialled at all.

Deleting one line from a layout removes this completely. That property is what makes it reasonable to try during a normal sprint rather than planning for it.
