How to install
The extension is not on the Chrome Web Store yet, so it is loaded manually. This takes about a minute and only needs to be done once.
Download and unzip
Save the extension file, then unzip it. Keep the folder somewhere you will not delete.
Open extensions
Enter chrome://extensions in your browser address bar and press Enter.
Turn on Developer mode
Use the switch in the upper-right corner of the extensions page.
Load Matheculator
Click Load unpacked, then select the folder you unzipped.
What it does
Calculator search
Type a name like mortgage, BMI or percentage in the toolbar and go straight to the right calculator.
Instant tools
Open the AI Solver, all calculators, your saved Calc-Kits and GMAT Prep in one click.
Works everywhere
The popup opens on any page, so the tools are there whenever a number appears.
Privacy
The extension requests no browsing permissions. It stores nothing about the pages you visit and only opens Matheculator pages when you click.
Which browsers
Works in Chrome, Edge, Brave, Arc and Opera, because they all use the same extension system.
Share this link
Send this page to anyone who wants the extension. They get the download and the same steps.

One thing to know
Chrome shows a reminder that this extension was loaded in Developer mode, and it will not update on its own. Nothing is broken; the reminder is Chrome's standard warning for manually loaded extensions.
