Claude RTL Toolkit by Reza Bagheri

Claude RTL Toolkit makes claude.ai genuinely usable for right-to-left languages — Persian, Arabic, Hebrew, and Urdu — and gives you full control over typography.

DIRECTION
• Flip each message between RTL and LTR with one click.
• Automatic detection of RTL scripts (English stays LTR, Persian/Arabic/Hebrew switch to RTL).
• Keyboard shortcut (Alt+Shift+R) for the last message; the input box follows what you type.
• Your choices are remembered across reloads and synced across your devices.

TYPOGRAPHY
• Independent font, size, and line-height for user messages, Claude's responses, the input box, and code.
• Bundled fonts: Vazirmatn & Estedad (Persian), Rubik (Hebrew), JetBrains Mono (code, with ligatures).

CODE
• Code blocks always stay left-to-right — even with right-to-left comments.
• Optional line numbers.

INTERFACE
• 5-language settings UI (English, Persian, Hebrew, Arabic, Urdu).
• Toolbar popup: on/off, set-all direction, line numbers, language.
• Import/export your settings.
