Morning, 07:02
Catch the dream before it fades.
Baku already knows you were up at 03:12 and asks one gentle question. Hold to talk with your eyes half open, give the night a moon, and you are done in under a minute.
For anyone who wakes at 3 a.m.
Rewrite
the night.
A calm way to change recurring nightmares, built on imagery rehearsal. Baku keeps watch, and help at night is always free.
- Built on imagery rehearsal research
- Free at night, always
- Private by default
Why Baku exists
Built for one person. Now for everyone.
Up to one in ten adults has nightmares every week. The method sleep medicine recommends had never been made for real life. “So I built it for my wife,” says Roman.
For a long time, my wife woke up from a nightmare almost every night. The nights didn’t stay in the night: tired mornings, a heavy day, a quiet dread as the evening came.
I looked for something that would really help, not just track it, and found nothing. So I built it for her. Baku joins very old wisdom about dreams with what sleep science knows today.
Now it is here for you too. I hope your nights get quieter. Ours are starting to.
The 24 hours
One app that follows the sky.
Bad dreams are not only a night problem. Baku helps across the whole day, and each moment has one clear job. Scroll from morning to 3 a.m.
Day, 13:40
Ten minutes that change the night.
Daytime is where the work happens. Rehearse the new ending of a dream you rewrote, learn one small, sourced thing about sleep, and note how heavy the day feels.
Evening, 21:50
A ritual that is yours.
Close the day, breathe slowly, rehearse once more. Build your wind-down from short steps, hear a note from someone who loves you, and watch the screen warm and dim toward bed.
Lights out, 22:31
Baku keeps watch.
When the ritual ends, Baku goes quiet. Nightlight stays one tap away, and nothing will buzz, badge or glow until morning.
3 a.m., 03:12
Help that needs no reading.
If you wake, the screen turns to a warm ember light on black. Breathe with a pulse you can feel, hear a voice you love, or say the dream out loud and leave it for the morning. Free, always.
Rewrite the ending
The dream keeps its beginning. You choose how it ends.
This is imagery rehearsal, the method sleep medicine recommends for nightmares. You never relive the whole dream. You only choose where it turns, change it any way you like, and rehearse the new version for a few minutes a day.
- 1Pick a nightmare, a milder one first
- 2Change it any way you want
- 3Rehearse 10 to 20 minutes a day
- 4Repeat with the next one
Step 1
Where does it turn?
Tap the moment you’d like to change. You don’t have to read the rest.
Tip: start with a dream that feels a little less intense.
An example dream. In the app, the Guide only nudges; your words stay your words.
Nightlight is free. Always.
If you wake at 3 a.m.
Most vivid dreams come in the last third of the night. So Baku keeps a warm, ember light on for exactly that hour. No blue light, nothing to read, at most three choices. It is free forever, it works offline, and it never asks you to sign in.
Breathe with a pulse you can feel
Phone on your chest, eyes closed. A soft heartbeat slows from about 60 to 50 beats a minute while you breathe out longer than in.
Hear a voice you love
A partner, parent or friend records a few words in daylight. At night it plays with the breathing: it was a dream, you are home.
Say it out loud, then let it go
Twenty seconds to get the dream out of your head. It waits for the morning, when you can decide whether to rewrite it.
Back to sleep
Slow rain and a body scan that fades out by itself. If sleep doesn’t return in twenty minutes, Baku gently suggests getting up for a while.
breathe with me
In for four, out for six. Long exhales tell your body it is safe to slow down.
The science
Built on what sleep medicine actually recommends.
Every method in Baku carries an evidence label, and every claim links to its source. Where the evidence is thin, we say so.

Old wisdom, new science
Every old ritual has a modern twin.
People have tried to tame bad dreams for thousands of years. Many of those practices map surprisingly well onto what research supports now. You choose which voices you hear: science, psychology, or a tradition of your own.
Judaism
Talmud, Berakhot 55
Friends gather to help turn a troubling dream toward good.
Modern twin. Rewriting the dream while you are awake.
Islam
Sahih al-Bukhari, Book of Dreams
After a bad dream, turn onto your other side and do not dwell on it.
Modern twin. Breaking the pattern, and not ruminating at night.
Ancient Greece
The temples of Asclepius
Sleeping in a sanctuary, hoping for a healing dream.
Modern twin. Dream incubation research at MIT.
Christianity
Compline, the night prayer
A night prayer for protection and a quiet night.
Modern twin. A calming ritual and a felt sense of safety.
Partner mode
For the person who wakes up too.
Often there is someone beside you who wakes up too and wishes they could help. Partner mode gives them a gentle way to, without ever reading a single dream. Partners join free.
A voice for 3 a.m.
Record a few calm words in daylight. If they wake at night, your voice plays with the breathing.
Bedtime notes
Leave something for tonight. It arrives as part of their evening ritual, never as a buzz at night.
Calm nights, together
If they allow it, you see a shared count of calm nights. Never the dreams themselves.
“I noticed”
Log what you saw (“you talked in your sleep at 3”) so the morning has the whole story.

A survey of almost 16,000 adults in 16 countries found weekly nightmares far more common than older single-country studies suggested. What it measured, and what it cannot tell us.

Questions
Honest answers.
Something else on your mind? Write to support@baku.care. A person answers.
All questionsIs Baku a medical treatment?
No. Baku is a wellness app built on imagery rehearsal, the method the American Academy of Sleep Medicine recommends for nightmares. It does not diagnose or treat any condition and does not replace a doctor or therapist. If your nightmares are tied to trauma, please work with a professional too; Baku can sit alongside therapy.
Is the 3 a.m. mode really free?
Yes, forever. Nightlight, with its breathing, back-to-sleep audio and the 20-second voice note, is free. It works offline and never asks you to sign in, pay or read anything at night.
Do I have to relive my nightmare?
No. You only tap the moment where you would like the dream to turn, then write how it goes instead. You never have to write the whole nightmare down, and we suggest starting with a milder one while you learn the method.
How soon could I notice a difference?
Research suggests many people find their nightmares come less often or feel less intense within a few weeks of rehearsing a new ending for about 10 to 20 minutes a day. Everyone is different. We will share Baku’s own results once we have measured them, and not before.
Who can read my dreams?
Only you. Dreams are private by default, can be locked behind Face ID or your fingerprint, and are never sold or used for advertising. You can export everything or delete your account at any time; deletion becomes final after a 30-day grace period. Entries you mark “keep private from AI” never reach the Guide.
What does Baku Plus cost?
Plus is 59.99 a year with a 7-day free trial, or 9.99 a month without one. Plus Family, for you and up to five others on iPhone through Apple Family Sharing, is 89.99 a year with the same trial. We remind you before the trial ends, and you can cancel any time in the App Store or Google Play. Nightlight, the journal, voice capture, the moon calendar and your first rewrite stay free.
When can I use Baku?
Baku is coming to iPhone and Android. We are starting with a small private beta for people who have nightmares often, then opening to everyone. Join the waitlist and we will write when it is ready.
