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. Privacy-first: no tracking, no analytics, no data collection. Everything stays in your browser.
