Download Leuria.

Free and open source. A small app for your Mac or Windows PC, not your phone: it waits in the menu bar until a website needs your AI.

On a phone?

Leuria runs on a Mac or a Windows PC, not on phones or tablets yet. Here it is on a shop that answers with your AI and fills in your order from a message.

First time on a Mac: allow Leuria once, in three clicks

Leuria is free and not registered with Apple, so your Mac can't check it and blocks it the first time. You allow it once, and it opens normally from then on.

  1. 1

    Open Leuria, then click Done

    Drag Leuria to Applications and open it. Your Mac says it can't open it: click Done, not Move to Trash.

  2. 2

    Click Open Anyway in Settings

    Open System Settings, then Privacy & Security. Scroll down to Security and click Open Anywaynext to Leuria.

    Open Privacy & Security
  3. 3

    Confirm, and you're done

    Your Mac asks once more: click Open Anyway, then use your password or Touch ID. Leuria opens, and you won't see this again.

First time on Windows: allow Leuria once, in two clicks

Leuria is free and new, so Windows doesn't know it yet and warns you the first time. You allow it once, and it opens normally from then on.

  1. 1

    Keep the download

    If your browser says the file isn't commonly downloaded, choose Keep. In Edge, click the … next to it first, and then Keep anyway.

  2. 2

    Open it, then click More info

    Open the file you downloaded. Windows shows a blue window: click More info, not Don't run.
