Dynamic RTL от Soroush

Persian and Arabic text on most websites shows up left to right: chat replies, tweets, comments, even the box you type in. Dynamic RTL fixes that.

It finds Persian or Arabic text as a page loads and as new messages stream in, and flips just that paragraph to right to left, with the Vazirmatn font. It happens before the page is painted, so there is no flash.

• Works on AI chats (ChatGPT, Claude, Gemini, Copilot, Perplexity and more), X, Instagram, YouTube, Reddit and other big sites
• English words inside a Persian sentence keep the site's own font
• Code blocks and links keep their own direction
• Chat boxes and inputs: each line gets its own direction as you type
• Lists, tables and headings are handled properly
• Sites that are already right to left are left alone
• Turn any site on or off from the toolbar, with Ctrl+Shift+Y or the right-click menu
• Upload your own font if you prefer
• Very light: pages without Persian or Arabic cost almost nothing
• No network requests, no analytics, no account
