A few little steps.
Then you’re in the flow.
Juicebox lives in your menu bar, with a small extension to keep your browser allowances fresh.
Meet your new menu bar buddy.
Download and unzip the source. In Terminal, open the extracted Juicebox folder, then run the command below.
Download Juicebox source
./make.sh --install
Requires Apple’s Swift toolchain, included with Xcode Command Line Tools. The build creates and installs Juicebox.app, then opens the guided setup. This is a source build, not a notarized app-store download.
Bring your browser along.
Juicebox has already prepared the extension and connected the local bridge for your installed Chromium browsers. One step is left, and its setup window walks you through it.
- Click Open chrome://extensions in the setup window, which opens the right page in the right browser.
- Enable Developer mode and choose Load unpacked .
-
Select
~/Juicebox/extension, or drag that folder onto the page. Use Reveal in Finder in the setup window to find it.
Sign in. Take a sip.
Sign in to Claude or ChatGPT in the browser where you loaded the extension. Open the Juicebox extension to refresh your readings.
Your allowances now live in the menu bar. Turn on Launch at login and keep Juicebox close.
A little help, if you need it.
Loaded the extension, but nothing happened?
Give it up to a minute — the extension reports on a timer, and Juicebox registers itself for whatever ID your browser gave it. The folder can live anywhere; the ID travels with it. Expand “Loaded it but nothing is happening?” in the Mac setup window to see exactly what is loaded where.
My provider says I’m signed out.
Sign in on that provider’s website in the same browser profile as the Juicebox extension, then press Refresh in the popup.
How do I reopen setup?
Click Juicebox in your menu bar, open Settings with the gear button, and choose Browser setup.
