How to choose
Match the extension to your main friction: content noise, tab chaos, or form work. Check current upvote velocity and recent updates since low-upvote tools like WA+ can still solve narrow problems. Avoid stacking multiple AI sidebars if they overlap in features. Watch for privacy claims on data-clipping tools like Uniclip before granting broad page access.
