Show HN: WindowSill
getwindowsill.app
Why WindowSill? Inspired by the MacBook Touch Bar, StreamDeck, and Apple Intelligence, I wanted a tool that gives context-aware actions without interrupting my workflow. WindowSill is my take on that idea for Windows.
What it can do
AI text assistant Select any text in any app to summarize, rewrite, translate, or fix grammar instantly. No copy/paste needed. No switching apps needed.
Short-Term Reminders Set reminders that can pop up as full-screen notifications, so you can't miss them. Perfect for ADHD brains, multitaskers, or anyone who needs a firm nudge to stay on track of things.
Clipboard history Access your recent copies without switching apps.
URL & text utilities Select any URL in any app to shorten it or generate a QR Code.
Media & Meetings controls Manage playback, mute/unmute from Microsoft Teams, even when the app is in the background or minimized.
Personalization Save custom prompts, dock the "sill" to the top, bottom, left, right, or change its size to reflect your style and needs.
All from a single, universal command bar that stays out of your way — no friction, no app switching.
Bonus: the app is extensible! It comes with an SDK allowing any app to integrate with WindowSill.
Who is it for? Mainly Windows power users, but also anyone looking to boost their productivity with AI-powered text assistance and quick access to useful tools.
