Features

The current script metadata includes these matches:

You can expand the @match entries later if you want the script to run on more sites.

Install a userscript manager such as Tampermonkey.
Open Tampermonkey and create a new script.
Replace the default template with the contents of tampermonkey-equation-copy.user.js.
Save the script.
Open or refresh ChatGPT, Gemini, Claude, or another matched site.

In those cases, Copy LaTeX may not be available.
Copy Equation depends on the rendered text being extractable from the visible equation markup.
Site DOM changes may require selector updates in the future.
