This is a quick, rough Tampermonkey script which detects content warnings on Twitter and turns them into collapsible drawers, like how they behave on Mastodon.

When a Tweet contains text that appears to be a content warning, the script will hide the content behind a <details> element and display only the warning itself:

(I have custom userstyles applied, so this will look slightly different on your browser.)

Clicking on the content warning or the arrow beside it will show the Tweet's content and allow you to interact with it:

To change the regex patterns used to detect content warnings, or expand certain warnings automatically, you'll have to edit the script.
