Whether you’re struggling with a quiet video or want to fly through long lectures without digging into settings menus, this tool is built for you. ✨ Key Features

Volume Boost (Up to 500%) Sometimes 100% just isn't enough. Using the Web Audio API, you can crank your audio up to 5x the normal volume—perfect for quiet laptop speakers or low-gain recordings.
Insane Speed Control Go anywhere from 0.1x (super slow-mo) to 16x (warp speed). Our smooth slider ensures you aren't stuck with standard presets.
Per-Tab Customization Each tab is independent. Boost a quiet video in one window while keeping your background music at a normal level in another.
Intuitive Overlay & Mouse Scroll Forget clicking the extension icon. A sleek badge appears directly on the video player. You can now tweak volume and speed instantly by simply hovering over the overlay and using your mouse scroll wheel.
