## What is SleepWiki?

Can't switch your brain off at night? SleepWiki replaces late-night doomscrolling with something calmer: one fascinating Wikipedia article at a time, read at your own pace, while rain, thunder or a crackling fireplace plays in the background.

No voice narration. No autoplay video. No feed designed to keep you awake. Just quiet reading and ambient sound until your eyes close.

HOW IT WORKS

• Swipe through cards of curated Wikipedia articles with beautiful imagery
• Swipe right to save an article to Favorites, left to pass on it
• Pick your reading length: Short (80–180 words) or Medium (260–520 words)
• Choose Factual mode to get straight to the point, or Soothing mode for a gentler, calmer narrative
• Search for a specific topic, or double-tap to open the full article in your browser

AMBIENT SOUNDSCAPES

Mix and match looping sounds, each with its own volume slider, to build the atmosphere you sleep best in.

Free sounds: pure rain, heavy rain, thunderstorm, birdsong, falling snow, sea waves, and a crackling fireplace.

BUILT FOR BEDTIME

• Dark, low-glare interface that is easy on tired eyes
• Audio keeps playing in the background — lock your screen and keep listening
• Explore Wikipedia in 10 languages: English, Turkish, French, German, Italian, Chinese, Spanish, Hindi, Arabic and Russian
• Topics across history, science, nature, technology, space and culture
• No ads interrupting your reading

SLEEPWIKI PREMIUM

Upgrade whenever you are ready:

• Unlimited passes — skip as many articles as you like (free accounts get 3 passes per day)
• Long reading mode — deep-dive articles of 780–1300 words
• 6 extra ambient sounds — city ambience, car ride, train, typewriter, banknote counter, and a calming 432Hz tone

Premium is available as a weekly, yearly or one-time lifetime purchase. Rain, thunder and the core sounds stay free, forever.

Turn curiosity into calm. Download SleepWiki, pick a sound, and read yourself to sleep.
