WindowSill is the ultimate command bar to help you work smarter on Windows. We place a customizable bar right between your taskbar and your apps, a slim ledge that keeps your favorite tools within arm's reach. Skip tracks, paste something you copied an hour ago, convert currencies, mute a meeting, or fix your writing, all without leaving the app you're in. A growing library of extensions lets you shape the bar around the way you work. ### Everything You Need, Always Within Reach WindowSill comes packed with productivity essentials that stay out of your way until you need them. Clipboard History saves everything you copy — text, images, URLs, colors — and lets you paste any previous item with a single click. Media Control lets you skip or pause your media from Spotify, YouTube, Apple Music, and virtually any player on your system. See your upcoming meetings from Outlook, Google Calendar, and iCloud within the bar. And the Currency & Unit Converter recognizes values as you select them, converting temperatures, lengths, currencies, crypto, and more in real time. ### Write Better, Everywhere Take your writing to the next level with the built-in AI Text Assistant. Select any text in any app and instantly fix grammar, rewrite for clarity, change tone, or translate into another language. No copy-pasting into a separate tool. It supports online models like ChatGPT and Claude, as well as offline models that run locally on your machine for complete privacy. Whether you're drafting an email, editing a report, or replying to a message, WindowSill helps you communicate with confidence. ### A Growing Extension Library Along with a rich set of built-in features, WindowSill provides a growing catalogue of free, community-built extensions. Meeting Control lets you mute, unmute, react, or leave a call directly from the bar, even when your meeting app is minimized. Group your favorite apps, files, and folders into launchable collections with App Launcher. Create custom keyboard chords and PowerShell automations with Universal Commands. Monitor CPU, RAM, and GPU temperatures in real time with System Monitor. Discover new extensions regularly and build a bar that's truly yours. ### Your Bar, Your Way WindowSill adapts to you. Anchor the bar to any edge of any monitor — top, bottom, left, or right. Choose from three bar sizes. Add or remove features as you see fit. From URL shortening and QR code generation to browser zoom, quick reminders, an inline terminal, and developer tools, there's always more to explore. ### WindowSill+ Unlock the full potential of WindowSill with a premium lifetime license or subscription. WindowSill+ gives you the AI Text Assistant — grammar correction, tone adjustment, translation, custom prompts, and more — along with additional UI customization options. A one-week free trial lets you experience it all before committing.
