Spine, on all your screens.

Supported browsers

• Chrome 120+
• Edge 120+
• Brave 1.61+
• Arc
• Opera
• Vivaldi
• Firefox 140+
• Zen
• Safari (coming soon)

Arc, Opera, and Vivaldi: any recent version, based on Chromium 120. Zen: any recent version, based on Firefox 140. Desktop only (macOS, Windows, and Linux); mobile browsers don't support extensions.

Install on Chrome, Edge, Brave, Arc, Opera, or Vivaldi

1. Unzip the archive, then move the resulting folder to a permanent location on your computer, such as your Documents folder.

   Your browser reads this folder every time it starts: if the folder disappears from your Downloads, the extension disappears with it.

2. Open the extensions page by pasting chrome://extensions into the address bar.

   On Edge, Brave, Arc, Opera, or Vivaldi, replace chrome with your browser's name: edge://extensions, brave://extensions…

3. Turn on Developer mode using the toggle in the top-right corner.

4. Click Load unpacked, then select the folder you moved in step 1.

5. Pin “Send to Spine” to your toolbar using the puzzle-piece icon.

The next time you start your browser, it will show a “Disable developer mode extensions” banner. Close it: it's not an error, and the extension keeps working. It's the usual message for an extension that wasn't installed from a store.

Install on Firefox or Zen

1. In Firefox or Zen, click “For Firefox and Zen” at the top of this page.

2. The browser asks whether it can install an add-on from this site: click Continue to Installation, then Add.

3. Pin “Send to Spine” to your toolbar using the puzzle-piece icon.

No developer mode, no folder to keep: the extension is verified and signed by Mozilla, and your browser keeps it like any other add-on.

First use

Click the Spine icon on any page. The first time you open it, enter your Spine address; you must be signed in to Spine in the same browser. Then choose a request template, adjust the text if needed, and click Send: your conversation opens with the page as context.

Updating

On Firefox and Zen, the extension updates itself. On other browsers, it doesn't update on its own. When a new version comes out, download the archive again from the same link, replace the old folder with the new one, then click Reload on the extension's card in chrome://extensions.

What the extension accesses

It reads the page only when you click its icon, and it requests network access only to your Spine domain. It doesn't read or store your login credentials.
