Get Leuria

Use the AI you already have, on the websites you choose.

Leuria is a small, free app on your computer. It connects the AI you already have to the websites that ask for it: an agent you sign in to (Claude Code, Codex, Gemini CLI and others), any OpenAI-compatible API with your key, or a model running on your machine. Each site asks first, you say yes once, and none of them ever sees your files.

A shop: its assistant answers from the shop's own stock, and fills an order from a message.

Set up once.

A small app. It waits in your menu bar until a site needs it.

First, get Leuria.

Leuria's window: Add an AI, step 1 of 3. An AI app you use, a model on this computer, or an AI service with a key.

Then pick your AI.

Leuria's window when a site asks: Kiln & Co. (demo) wants to use your AI. Answers with Claude · Haiku 5.5, right for this site. It can ask your AI to answer you and let it use this site's features; it can't see your files or run programs, or see what you do on other websites. Not now, or Allow.

Then a site asks.

The shop's Ask us panel, answered by your AI, Claude · Haiku 5.5: the cheapest mug is the plain white mug at €7, with 130 in stock.

Then it answers, from your AI.

Every site asks first.

A website can't use your AI until you say yes, in Leuria's own window. The window says what it may do, and what it may not.

A site you allow can
Ask your AI to answer you.
Let your AI use that site's own features: search its products, read its notes.
It can't
See your files, or run programs on your computer.
See your password or your AI account.
See what you do on other websites.
And you
See every connected site in Leuria, with the AI that answers it, and disconnect any of them in one click.
See what each site asked of your AI today, and pause any site that asks too much. No site can ask more than 120 times an hour, or 20 times from a tab you are not looking at.
With a model on your computer, nothing leaves it at all.

Works with
the AI you have.
