One click from any tab
Click the moon in your toolbar and your sound starts. It keeps playing when you close the popup or switch tabs, and Alt+Shift+N plays or stops it from anywhere.

What it does
A steady sound for deep work
Focus sessions that fade
Pick 25, 50 or 90 minutes. The toolbar badge counts down, and the sound fades out over 20 seconds at the end, a gentle cue to take a break instead of an alarm.
Twelve free sounds
Brown, pink and white noise, gentle rain, a box fan, real ocean waves and more. Generated live or crossfaded, so nothing loops, and matched in loudness, so switching never jumps.
Private by design
No ads, no account, no analytics. The extension collects nothing and needs no access to the pages you visit.
Which sound?
Brown for long sessions, white against voices
Brown noise is soft enough to sit inside for hours. Pink is an even all-day sound. White noise is strongest against a café or open office. Our studying and focus guide compares them, and brown noise for ADHD covers what the research says.

Questions
About the extension
Is the Sleepy Noise extension free?
Yes. The 12 core sounds and focus sessions are free with no ads. Lifetime sound packs live in the phone app.
Does it keep playing if I close the popup?
Yes. Sound keeps going across tabs until you stop it or a focus session ends. It stops if you quit Chrome.
Does it work in Edge or Brave?
It's built for Chrome and works in most Chromium browsers that install from the Chrome Web Store, including Brave and Microsoft Edge.
Does the extension collect any data?
No. It has no analytics and no access to the sites you visit. It only remembers your sound, volume and timer on your computer.
Can I use it to fall asleep?
You can, but a phone on the nightstand is easier: the free Sleepy Noise app plays all night with the screen locked and starts from the lock screen in one tap.
