ThickGPT

ThickGPT is a Chrome extension that enhances the ChatGPT interface by making the text input area physically taller. When you type long prompts or paste substantial code snippets into ChatGPT, the default input box can feel cramped, requiring constant scrolling. ThickGPT automatically increases the height of the textarea, giving you more vertical space to compose your messages without the need to manually resize the box each time. This is particularly useful for developers writing multi-line code, researchers pasting lengthy queries, or anyone who often works with detailed instructions. The extension works seamlessly with the standard ChatGPT web interface, adjusting the input field to a comfortable height that matches your screen size and reduces visual clutter.

Features

• Automatically enlarges the ChatGPT input textarea: The extension detects the ChatGPT page and applies a fixed height increase to the text input field, so you no longer have to drag the corner handle to expand it manually. This saves time and keeps your workflow smooth.
• Works on the main chat page: ThickGPT activates on chat.openai.com and similar domains where the ChatGPT interface is loaded. It does not interfere with other websites or require any configuration.
• Lightweight and no extra UI: The extension adds no buttons, popups, or settings panels. Once installed, it runs silently in the background. You can forget it is there until you notice the extra room while typing.
• Compatible with ChatGPT updates: The extension uses standard DOM manipulation that remains functional across minor ChatGPT interface changes. It targets the textarea element by its common attributes, ensuring reliability.

Use ThickGPT if you find the default ChatGPT input box too small for your needs. It is ideal for users who compose long-form responses, paste code examples, or want a more spacious typing area without switching to a separate editor. The extension does not alter any other part of the ChatGPT interface, preserving the original layout and functionality.
