Stopping the late-night scroll
At your bedtime the browser goes quiet instead of serving another feed.
Sleep
A bedtime for your browser, not just for you
Set the hours you mean to be asleep. When they arrive, the screen goes quiet and offers a breathing rhythm instead of another feed.

click the toggle — this is the real interface, not a screenshot
You did not plan to be awake at one in the morning. You planned to check one thing.
How it works
Decide once, in daylight
The rule you set at noon is calmer than the choice you make at midnight.
01
Set your hours
For example eleven at night until seven in the morning. Ranges that cross midnight work properly.
02
The screen winds down
At bedtime the browser turns into a calm full-screen space instead of a bright page.
03
Breathe with it
An animated guide sets the rhythm. Relax is free; Focus, Sleep, Balance and Deep Sleep come with Pro.

Any hours, including ranges that run past midnight.

It holds against the blocker
If both are on, blocking wins over sleep — the stricter rule is never overridden by the softer one.

Common cases
What bedtime mode is set up for
A schedule that crosses midnight
Eleven at night to seven in the morning is handled as one range, not two.
Winding down instead of being cut off
A breathing rhythm rather than a slammed door — the point is to fall asleep, not to fight software.
Keeping the phone habit out of the laptop
The hours you set apply to the browser you actually work in.
When you truly need something firmer
Put those sites on the blocklist with a password. Blocking always outranks bedtime.
What sleep mode knows
Your schedule and how long the mode ran are stored in your browser. We do not receive your bedtime, and we do not receive what you were doing before it.

About Sleep
Can I set hours that cross midnight?
Yes. Eleven at night to seven in the morning is handled as one range, not two.
Can I get past it if I really need to?
Yes — it is a wind-down, not a lock. If you want something you cannot argue with, put those sites on the blocklist and set a password.
Which breathing techniques are free?
Relax. Focus, Sleep, Balance and Deep Sleep are part of Pro.
What happens if focus mode is running at bedtime?
Only one mode is ever on screen. We tested every pairing: blocking outranks sleep, and sleep outranks focus and zen.
The other eleven
They work together, not instead of each other
Sleep is one of twelve modes
Blocking, focus, screen time, dark mode and eye care are all included, free.
