About this extension

Tired of the narrow chat window wasting your wide screen?

WideChat expands the conversation area in your favorite AI chats to use the full width of your monitor. No more squinting at a narrow column in the middle of the screen while the rest sits empty.

Works with all major AI chats:
- ChatGPT
- Claude
- Gemini
- Grok
- Qwen
- DeepSeek
- Kimi
- Copilot

Why WideChat?
- Configurable width: choose anywhere from default to 100% full screen
- Works instantly: the chat expands automatically when you open the site
- Lightweight: WideChat only adjusts CSS, zero performance impact
- Free and open source

Whether you're reading long AI responses, reviewing code, or having a deep conversation, WideChat gives you the screen space you paid for.
