Installation
Web Highlights is a browser extension and is available in the Chrome Web Store, Microsoft Edge Add-ons, and Firefox Add-Ons.
Although Web Highlights - PDF & Web Highlighter isn't directly available in Brave, Vivaldi and Opera, you can still install it because they are Chromium-based browsers.
On Android, there is also the Web Highlights app on Google Play, a companion app to the extension — see Install the Android app.
