Claude Studio — RTL, Fonts & Themes de ILYAGVC

Make Claude truly yours. Claude Studio restyles claude.ai and claude.com with first-class right-to-left support, beautiful multilingual fonts, professional typography, and rich theming — all from a clean popup with a live preview.

Whether you chat in Persian, Arabic, Hebrew, or Urdu, switch languages mid-conversation, or simply want Claude to look and read better, Claude Studio gives you precise control — without changing anything you don't want to touch.

🌐 Right-to-left, done right
• Full RTL layout for Claude's interface and messages
• "Auto" direction sets each message — even each block — from its own content, perfect for bilingual chats
• Math (KaTeX) and code always stay left-to-right and intact, so nothing breaks
• Localized digits (e.g. ۱۲۳) in conversations and the chat list, while your input and code stay untouched

🔤 Fonts & typography
• 50+ curated fonts, grouped by script — pick separate fonts for body text, headings, and code
• Fine-tune weight, size, line height, letter spacing, word spacing, and paragraph spacing
• Text alignment: right, left, center, or justify
• Limit the reading width for comfortable reading on wide screens

🎨 Themes & colors
• Light, Dark, and a true Black theme
• Set Claude's accent/highlight color and the code-box theme to match your taste

🎯 Precise scope
• Choose exactly what gets styled — Claude's replies, your messages, the composer, and the chat list — each independently

⚙️ Power-user tools
• Save, apply, and manage presets
• Add your own custom CSS
• Export and import all your settings
• Keyboard shortcuts to toggle the extension and open settings
• A 25-language interface with a live preview of every change

🔒 Private by design
• No accounts, no tracking, no data collection — your settings stay in your browser. (Fonts load on demand from Google Fonts.)

💻 Open source
• Free and open source — view the code, report issues, or contribute on GitHub: https://github.com/ILYAGVC/Claude-Studio (MIT License).
