AI Sidebar — ChatGPT, Claude, and Gemini in one Chrome side panel. 100% free. Unlimited usage. Stop juggling browser tabs. AI Sidebar is the all-in-one AI assistant for Chrome that puts ChatGPT, Claude, and Google Gemini right inside your browser's side panel — so you can chat with any AI model without ever leaving the page you're working on. No sign-up for the extension. No paywall. No usage caps from us.

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.
