Get Leuria

AI features on your site, on your visitors' AI.

Your visitors already have an AI: an agent they sign in to, an API with their key, or a model on their computer. Leuria connects it to your page. You add a button and a few lines of code; nobody pays for a new model, and your data never leaves your page.

  • No AI bill, no key to hide
  • Your tools run in your page
  • Every visitor says yes first
The Kiln & Co. demo shop: three mugs, their prices and stock, and the Connect your AI button
Kiln & Co., a demo shop. Its assistant answers from the page's own stock, with the visitor's AI.

What changes for you.

The AI is your visitor's. The features, the tools and the data are yours, in your page, in your code.

You get
An assistant, answers from your docs, search by meaning, a form filled from a message.
Tools the AI calls in your page: search your catalogue, read your notes, book a slot.
You don't need
An AI bill, or a key in your page or on your server.
A server at all: every demo below is static files.
Your visitor sees
Leuria's window, which says what your site can and can't do. Nothing runs until they say yes.
What your site asked of their AI today, in Leuria. A site is capped at 120 questions an hour, 20 from a background tab, and the visitor can pause it. Their AI is theirs to spend.
Without Leuria, the same feature can use the browser's built-in AI, or your own server.

Five sites
that already do.

All demos

Add the button, then ask.

“Connect your AI” handles the rest: finding Leuria, asking the visitor, and offering another AI when they don't have it. Plain JavaScript, React, or any framework.

Start with the quickstart
shop.js
import { createAI, leuria, promptAPI } from "@leuria/client"
import { setDefaultClient } from "@leuria/connect"

const ai = createAI({ providers: [leuria(), promptAPI()] })
setDefaultClient(ai)   // <leuria-connect-button> uses it

const answer = await ai.chat({
  prompt: "A mug that keeps tea warm, under €30?",
  tools: [searchProducts],   // runs in your page
}).text()

Open source, from the button to the app.
