Explain it like I’m 5

Give me a lighthearted recap

The Windows taskbar is in the perfect position to serve as a productivity hub, yet it feels criminally underutilized. The Start Menu feels like a way for Microsoft to push its own apps, the widgets don't feel like much more than distractions, and I still manage to click the wrong thing when looking for items in my system tray.<br>However, WindowSill is an app that elevates the taskbar experience to something that feels like it should've just shipped with Windows. And it has completely changed how I use my taskbar nowadays.

What is WindowSill?

A command bar that makes your taskbar more useful

WindowSill's developer describes it as a productivity tool that helps those who struggle with context switching. The app creates a command bar that sits above your taskbar and provides a range of shortcuts and utilities.<br>These utilities are provided via extensions that you can enable or disable. Some of the default extensions that come with the app include image conversion and resizing, media controls, clipboard history, currency conversion, short-term reminders, and upcoming meetings.<br>Short-term reminders and calendar event integration are among the app's best productivity features, since you can set them to trigger full-screen notifications. While the integration with Google Calendar is not currently working, I was able to sync my Outlook calendar with WindowSill to get meeting reminders.<br>The premium plan also allows you to use AI to analyze and rewrite content without copying and pasting text into a new window.

Windowsill makes certain workflows much easier

No more buried menus or separate apps

While its AI features may be what draws some users to the app, my favorite WindowSill tools are the ones that save me time in my daily workflow. The image resizing tool, for example, makes it incredibly easy to resize a picture without needing to open a separate app. It even works more quickly than the PowerToys Image Resizer tool.<br>With WindowSill, I can simply drag an image to the command bar and then select the resize option. I can then enter the new size I want for the image and whether I want it to maintain its current aspect ratio. WindowSill then exports the resized image to the same folder. You can also use the tool to convert or compress an image. This saved me a ton of time on some recent articles, since I no longer needed to open an image-editing app to resize the pictures.<br>WindowSill also saves time for my clipboard history and currency conversions. I can technically access my clipboard history using the Win + V shortcut on my keyboard, but the clipboard icon on WindowSill gives me a useful shortcut where I can see my recently copied items, including screenshots.<br>With currency conversions, I can set the target currency to the South African Rand. Then, when I select an amount in a foreign currency, such as $500, WindowSill provides a quick conversion in the command bar. I find this particularly helpful when calculating how much I will be paid by a client, since it saves me the hassle of opening a search engine to convert the amount.

Customization lets you make Windowsill your own

Use as many or as few tools as you want

WindowSill has plenty of customization features so that you can get the tool to work in a way that suits you. For example, I disabled the AI Writing and Analysis extension since I don't use AI tools with my writing. You can also download additional extensions, including a screen recorder and an inline terminal.<br>You can also adjust the bar's appearance and where certain shortcuts appear, which is a handy bit of customization. You can even technically move the bar to another part of the screen if you don't want it attached to your taskbar.

It's this versatility that makes it such a useful app. It's packed with features, but you can pick and choose the ones you want to use. If an extension doesn't fit your...
