Claudia

Turn Claude into Claudia, in any color you like.

Claudia is a free browser extension that renames "Claude" to Claudia (or any name you choose) and swaps Claude's
orange for your own color: buttons, logos, highlights, the tab icon and more, live, without reloading.

Features

• Custom name: Claude becomes Claudia, or Samantha, or Jarvis, or anything up to 32 characters. Capitalization is kept
  (Claude / claude / CLAUDE), and it also updates the page title, the chat box placeholder and logos.
• Custom color: pick any color (color picker, hex code, or a ready-made swatch). The whole interface follows,
  including the send button, the starburst logo, inline code and text highlights.
• Tab icon: the browser tab shows a starburst in your color.
• Three independent switches: Brand Text, Custom UI (colors) and Tab Icon can each be turned on or off, globally
  or per website. Turning something off restores the original instantly.
• Master power button and a website exclusion list.
• Light and dark popup, plus a pop-out window.
• Optional: work on every website (off by default). Replaces "Claude" in text on any site and recolors Claude's
  orange logos and avatars you see around the web (for example the @claudeai profile picture on X). Your browser asks
  for permission first, and turning the switch off takes the permission back.

Claudia leaves things alone that you'd not want changed: code blocks, text you type, and technical names such as
claude.ai or claude-sonnet-4.

Privacy

Claudia runs only in your browser. It has no server, no analytics, no tracking and makes no network requests. Your
settings are stored locally in your browser. By default it only runs on claude.ai, claude.com and anthropic.com;
it gets access to other sites only if you turn on Work on every website.

This extension was written entirely by AI: the first version by Gemini 3.8 Flash, then rebuilt, hardened and
tested by Claude Sonnet 5.5.
