Claude RTL Fix

About

Claude RTL Fix repairs the rendering of mixed Arabic and English text on claude.ai.

THE PROBLEM
On a left-to-right page, Arabic paragraphs that contain English words, numbers, or punctuation can render with characters in the wrong visual order — question marks land on the wrong side, parenthesises numbers flip, and inline English breaks the natural reading flow.

THE FIX
The extension applies CSS unicode-bidi: plaintext and dir="auto" to message paragraphs, so each block resolves its direction from the first strong directional character. Inline mixed content is handled by the Unicode Bidirectional Algorithm exactly as it should be.

WHAT IT DOES
• Auto-detects paragraph direction (RTL vs. LTR) per message — no manual switching.
• Right-aligns paragraphs that start in Arabic, left-aligns paragraphs that start in English, all within the same conversation.
• Forces code blocks to stay strictly LTR so identifiers, syntax, and indentation never scramble — even when surrounded by Arabic.
• Fixes the input composer so typing mixed content behaves correctly as you type.
• A toolbar toggle lets you turn it off without uninstalling.

WHAT IT DOESN'T DO
• No data collection. No analytics. No network requests.
• No access to your messages or account.
• Only runs on claude.ai — inactive everywhere else.

PERMISSIONS
• storage — to remember your enabled/disabled preference.
• Access to claude.ai — required to apply the bidi fixes to the page.
