Read without losing your place.
A browser extension that dims the page around the line you're reading. Built for people with ADHD, dyslexia, and anyone who finds long articles hard to finish.
Focus spotlight
A movable band of light that follows your cursor. Everything else fades into the background so your eyes stop wandering.
Auto dim
When you stop moving the cursor, the page gently dims further. The longer you sit still, the calmer it gets.
Keyboard shortcuts
Adjust the height, width, and position without leaving the keyboard. Designed to stay out of your way.
Smart Window Pro
Element-aware focus that snaps to paragraphs, headings, and sections. Step through a long article with Shift+↓.
Custom tint
Soft blue for daytime, warm amber for late nights. Pick any color; change it as your eyes need it.
Private by default
No accounts, no analytics, no data sent anywhere. Settings live on your device and sync only through your browser's built-in sync.
Free forever. Pro when you need more.
All the core focus features are free. Smart Window is Pro — try it free for 7 days.
