The Best New Productivity App for Windows: Windows Sill

If you’re looking for a new way to boost your productivity and add smart features to your Windows PC, you should definitely check out WindowSill. It’s a free app available on the Microsoft Store that acts like a modern, customizable bar — similar to the taskbar — but with a lot of extra features built in.

What is WindowSill?

Windows Sill is a lightweight tool that sits on your screen (you can place it at the top, bottom, left, or right) and gives you quick access to useful functions. Think of it as an enhanced taskbar that adapts to what you’re doing.

By default, it opens at the bottom of your screen, but you can resize it, move it around, and even make it tiny if you prefer minimal space usage. It’s still in preview mode (beta), so you might run into a few glitches, but overall, it works surprisingly well.

Key Features of WindowSill

Here’s what makes WindowSill interesting:

• Clipboard Manager: Quickly view, manage, and clear your clipboard history.

• Quick Reminders: Add simple reminders so you don’t forget important tasks.

• Context-Aware Actions: Depending on what you’re doing, WindowSill suggests helpful actions. For example:

  • Playing music? You’ll see media controls.

  • Browsing the web? You can zoom in/out, summarize text, or shorten URLs.

  • Select a link? Instantly generate a QR code to share.

• AI Features: With WindowSill Plus (premium) or your own AI API key (like OpenAI or Gemini), you can analyze and summarize text, among other things. You can even run local AI if you have a powerful PC.

• Extensions: Add more functionality through extensions. For instance, you can install a performance counter to monitor CPU, GPU, and RAM usage right from the bar.

• Image Tools: Drag and drop an image to resize, convert, or compress it instantly.

Free vs Premium

The app is free to use, and most features are available without paying. However, advanced AI-powered tools require either:

• A Windows Sill Plus subscription, or

• Your own AI API key, or

• Running local AI models if your system supports it.

Why You Should Try It

WindowSill isn’t just a fancy taskbar — it’s like a smart assistant for your PC. From quick reminders and clipboard history to AI-powered actions and performance monitoring, it gives you tools that can genuinely save time and make your workflow smoother.

Since it’s still in beta, new features and extensions are being added regularly. That means it will likely get even better over time.

Final Thoughts

If you like experimenting with productivity tools or just want a smarter way to manage everyday Windows tasks, WindowSill is worth a try. You can get it for free from the official Windows Sill website or directly from the Microsoft Store.
