WindowSill
Windows command bar bundling clipboard, media, meetings and reminders with AI text tools that need no API key

getwindowsill.appAbout WindowSill
WindowSill is a command bar for Windows — a persistent strip that sits between the taskbar and your applications and collapses a pile of small utilities into one surface. The free application covers the mechanical productivity layer: clipboard history, media control, event reminders and short-term reminders, a unit and currency converter, meeting control for Teams, image and video utilities, web browser control, and an extensions system for adding more. The paid tier, WindowSill+, is where the AI lives, and its most notable commercial decision is that no API key is required — the vendor supplies the model access as part of the subscription, which removes the single most common drop-off point for non-technical Windows users evaluating an AI utility. The AI features are text-centric rather than chat-centric: an analyzer, a rewriter, translation across 35+ languages, spell and grammar checking, custom saved prompts and a prompt generator, all invoked against whatever text is on screen or in the clipboard. Distribution is through the Microsoft Store, and the site quotes user testimonials pulled from Store reviews and YouTube. As a category this is Raycast's territory, and WindowSill's argument is simply that Raycast is a Mac product and Windows users have been underserved. A lifetime purchase option exists alongside the monthly and annual plans.
