Why compare?

AIPRM, ChatGPT Superpower, and ChatGPT Toolbox are the three most widely installed ChatGPT browser extensions. Each one works on ChatGPT only. GPTPowerUps works on ChatGPT, Claude, and Grok from a single install — no duplicate installs, no separate subscriptions per host. All three competitors have a free tier of some kind; each one has documented limits that reduce usability unless you pay. GPTPowerUps Solo is free with no expiry and no email required at install. These three pages lay out the factual differences so you can judge for yourself.
