Description
Apply resilient, token-first themes (dark, light, AMOLED & more) to ChatGPT and Claude.ai. Not affiliated with OpenAI or Anthropic. Theme ChatGPT and Claude.ai the way you want — one extension, both apps. AI Chat Themes applies clean, readable color themes to chatgpt.com and claude.ai: a balanced Dark, a crisp Light, true-black AMOLED for OLED screens, plus instantly recognizable palettes — Dracula, One Dark Pro, Night Owl, Synthwave '84, Material Ocean, Catppuccin Mocha, GitHub Dark, Cobalt2, and Ayu Mirage. • One-click theme switching from the toolbar popup, applied instantly with no reload. • Independent per-site control — theme ChatGPT and Claude separately, or turn either off. • Create and edit your own themes. Add images, change fonts and create your own experience. • Built for resilience: themes target each app's design tokens first, so they keep working across routine site updates, and safely fall back to the native look if a surface ever can't be themed. • Privacy-first: no prompts, responses, page content, or personal data are ever collected. Settings stay on your device. Not affiliated with OpenAI or Anthropic.
