Scored by a Toolio reviewer after real useOur verdict
Block Enter Chrome Extension stops the Enter key from submitting an unfinished ChatGPT message, switches sending to Ctrl or Cmd plus Enter instead, and lets users customize or toggle these behaviors to fit their typing habits. People who often hit Enter mid-thought and send a message too early get a simple fix built around a shortcut. Changing the default behavior can feel unfamiliar without some adjustment time, and users unfamiliar with shortcuts may find the change harder, without much in-app guidance, to adapt to.
