82Browser sidebar that puts GPT, Claude, Gemini, and other models next to any page you're reading.
251 tools in the catalog come as a Chrome extension; 201 of them have a free plan and 82 also offer an API. Below are the top 60, ranked by Effect score โ how much each tool is used and rated, how widely it is listed elsewhere, and whether it is alive.
An AI Chrome extension puts a model inside the pages you already have open โ summarizing an article, drafting a reply in a web mail tab, translating or reading a page aloud โ instead of making you copy text into a separate app. The trade-off is access: an extension that works on every site can usually read every site you visit, so what it asks for at install matters as much as what it does.
