ChatGPT RTL Fix by Amin B

ChatGPT RTL Fix is a lightweight Firefox extension for Persian and other RTL users who frequently mix RTL text with English technical terms on ChatGPT.

It fixes bidirectional rendering at the semantic block level instead of forcing an entire ChatGPT response into RTL.

• Correct Persian/English mixed sentences
• Handles sentences that begin with English technical terms
• Correct direction for mixed lists and individual list items
• Correct direction for mixed tables and individual cells
• Keeps URLs and citations isolated as LTR
• Keeps programming code, inline code, math, and CodeMirror editors LTR
• Handles ChatGPT Plain Text blocks that contain Persian prose
• Handles embedded Writing Blocks independently
• Fixes the ChatGPT prompt composer
• Supports streamed and dynamically inserted responses
• Does not modify unrelated ChatGPT UI controls

All processing happens locally in the browser.

The extension does not collect, store, transmit, sell, or share conversation content or any user data. It contains no analytics, trackers, remote code, background scripts, or network requests.


The extension runs only on chatgpt.com.
