⚡ How it works

Install the extension (free, takes one click) Pin it to your Chrome toolbar Click the icon on any page to open the AI side panel Pick ChatGPT, Claude, or Gemini from the sidebar nav Sign in to the AI the first time — your session is remembered Chat away while you browse, read, or work 🔒 Privacy Your chats go directly between you and the AI provider (OpenAI, Anthropic, Google). We don't proxy your conversations, we don't collect your prompts, we don't run analytics on what you type. The extension stores only your tiny UI preferences (which AIs you want visible) locally in Chrome.

🌐 Supported AI models ChatGPT (GPT-4o, GPT-4, GPT-5, o1) • Claude (Opus, Sonnet, Haiku) • Gemini (1.5 Pro, 2.0 Flash, and newer as Google ships them). You always get whatever model your signed-in account has access to.

🤔 FAQ

Is this really free? Yes — the extension is free forever, and it does not charge for usage.

Do I need an API key? No. You use the regular web versions of ChatGPT, Claude, and Gemini, signed in to your own accounts. No API setup.

Does it work with the free version of each AI? Yes. Free, Plus, Pro, Team — whatever plan you have on the AI's website, you get inside the sidebar.

Why do I need to sign in inside the sidebar? Because the extension opens the real ChatGPT / Claude / Gemini websites in a side panel. Your sessions are handled by those providers, not by us.

Can I use it on any website? Yes. The side panel sits next to whatever page you're browsing.

Does it slow down Chrome? No. The AI loads only when you open its panel.
