Scored by a Toolio reviewer after real useOur verdict
This extension applies a custom CSS stylesheet to the ChatGPT web interface so the conversation dialog box expands to fill more of the screen. It does nothing beyond that single visual tweak, with no added features, prompts or model access. Anyone annoyed by ChatGPT's cramped chat width gets a quick fix, while anyone hoping for extra functionality will find the tool does only this one thing.
