Scored by Alex after real useOur verdict
InstantGPT opens with a double tap of the Shift key on any webpage, giving you an AI assistant you can customize with its own character or tone. It works without switching tabs, so answers appear right where you're browsing. The free install includes in-app purchases, and with just one rating on record there's little outside evidence of how well it actually performs.
