82Browser sidebar that puts GPT, Claude, Gemini, and other models next to any page you're reading.
199 tools in the catalog have a Windows app; 144 of them have a free plan and 50 also offer an API. Below are the top 60, ranked by Effect score — how much each tool is used and rated, how widely it is listed elsewhere, and whether it is alive.
These AI tools install on Windows rather than living only in a browser tab. A desktop app can work across every program on the PC — rewriting selected text, transcribing calls, searching your own files — and some run models locally on the graphics card or on the NPU in newer laptops. That reach is also why it is worth knowing who publishes the app and what it sends back.
