RTL Fixer
Right-to-left for AI chats
Free
RTL Fixer fixes a small but constant frustration: every Safari extension I tried for right-to-left text in AI chat apps either did nothing, or flipped the entire interface and broke the sidebar, buttons, and input fields. So I built one that doesn't.
When you write to Claude or ChatGPT or any site that you add in Persian, Arabic, Hebrew, or another right-to-left language, the reply renders with right-aligned text. When you write in English, the reply stays left-aligned. Code blocks always stay left-aligned. The interface itself never flips.
HOW IT WORKS
RTL Fixer only touches markdown content: paragraphs, list items, headings, blockquotes, table cells, and similar semantic elements. It never touches the sidebar, the message composer, or any other interface element. There are zero platform-specific selectors, so platform updates do not break it.
Direction is detected using the first strong directional character in each paragraph. A paragraph that starts with English and contains Arabic stays left-aligned. A paragraph that starts with Persian and contains an English variable name stays right-aligned. Numbers, punctuation, and emoji are treated as neutral.
SUPPORTED SITES
- Claude (claude.ai)
- ChatGPT (chatgpt.com)
You can add any other site from the toolbar popup. Custom sites work the same way: enable the extension, type the hostname, and reload.
PRIVACY
RTL Fixer does not collect, transmit, or store any data. Everything happens locally in your Safari browser. There are no analytics, no advertising identifiers, no cookies, and no third-party SDKs. Your preferences (which sites you have enabled) are stored locally in Safari and never leave your device.
The extension only runs on sites you have explicitly enabled, either from the built-in list or by adding them yourself.
REQUIREMENTS
- macOS with Safari 17 or later
- iOS, iPadOS 17 with Safari
LANGUAGES
The extension itself is in English. The text it processes can be in any right-to-left language: Persian (Farsi), Arabic, Hebrew, Urdu, Yiddish, and others.
Ratings & Reviews
This update improves right-to-left text and the toolbar popup.
• Bulleted lists, numbered lists, and quotations now align fully to the right when their text is right-to-left, including the marker and the quotation bar.
• English text nested inside a right-to-left list or quotation now stays left-aligned instead of flipping.
• Detection covers more right-to-left scripts.
• Turning sites on and off, and adding or removing custom sites from the popup, is more reliable.
• When adding a custom site you can paste a full web address and the site name is filled in for you.
• Improved reliability on fast-updating chat pages
• more accurate right-to-left detection in edge cases(hidden website elements etc)
• better handling of site permissions changed in Safari Settings
