FatGPT — ChatGPT Width Control — Karl Stencell

Tired of ChatGPT’s cramped layout? FatGPT lets you widen or narrow the chat column with a slider or quick keyboard shortcuts. No clutter, no gimmicks — just control over how much space your chat takes.

What it does:

• Resize ChatGPT’s conversation column instantly
• Use Alt + . and Alt + , to adjust width. Alt + M to maximize, Alt + 0 to reset.
• Remembers your preferred layout automatically
• Works on chat.openai.com and chatgpt.com

What it doesn’t do:

• Doesn’t collect, track, or share any data
• Doesn’t need an account or email
• Doesn’t access the internet or external servers
• No paywalls or locked features — everything is free

All settings are stored locally in your browser. It’s a small, single-purpose extension that just makes ChatGPT feel right on your screen.
