“Hours dissolve unnoticed.”
“This integrates seamlessly into active work, enabling sustained flow during research writing where hours dissolve unnoticed.”
“Kind of like a coffee or pill, but subtle. I recommended it to my whole team.”
Get focused. Stay there.
Steady a busy screen
One rhythm runs across everything you have open, instead of every app pulling at you.
Lock in faster
No setup, no breathing exercise, no second app. Your attention drops in fast.
Stay with the task longer
A subtle rhythm of light and sound gives your attention something to hold onto.
Snap back into focus
Drifting? Slide back to the work without leaving the screen.
The problem
Your screen pulls you apart.
Every tab, window, and ping tugs you elsewhere. Holding focus on top of it is a second job, run on willpower alone. Most tools fight you: blocking, locking, nagging. Vayl goes the other way: one steady rhythm on the screen you’re already on.
A focus layer for your desktop.
Runs over the apps you already use, adding a subtle rhythm to screen and sound. Six parts, one switch.
Made for your hardest hours
Runs over these and anything else on your screen.
See-through rhythm
Pulses across your screen at the brainwave rhythms your attention locks onto, without covering your work.
Audio rhythm
Optional sound runs in sync with the visuals, so eyes and ears reinforce the same rhythm together.
Real-time adaptation
With permission, it reads camera and activity to adjust as your attention shifts.
Focus modes
Deep Work, Sprint, Marathon, Wind Down. From light, steady work to deep focus.
Intensity controls
Dial it up for more support, or keep it barely-there in the background.
Privacy controls
You control every permission. Built to support your attention, not watch your work.
Matches the beat of these and anything else you play.
Focus with your favorite music.
Nothing’s more engaging than your favorite music. With Vayl, it becomes focus music, not distraction.
- Works with the music you already use. Keep your playlists; Vayl adds its rhythm on top.
- Screen and sound move together. What you see lines up with what you hear.
- Better for long sessions. Your own music keeps long work from going stale.
Try it on your next block of real work.

Three claims, three receipts.
Your brain follows the rhythm
Vision is the brain’s widest channel. A steady rhythm on screen makes the visual cortex lock on and hold. The response is called SSVEP. Sound reinforces it; vision carries it.
The rhythm sets your state
Hold the rhythm and attention holds with it. Run it faster for sharp problem solving, slower for endurance.
Tested on top of real work
The stimulation sits over the task itself, tuned for comfort. The state arrives while you work, not in a session before it.

It runs on your machine, and stays there.
Vayl reads only what it needs, and reads all of it on your device. Nothing about your screen, typing, or camera is uploaded, sold, or stored.
Draws light on top of your desktop. Never captures, records, or transmits what’s on screen.
Plays the rhythm and can follow your music’s tempo. Listens for the beat, never the content.
Off until you turn it on. Reads your attention to adapt in real time. Processed on-device, never stored or sent.
Off until you turn it on. Reads keyboard and mouse timing to sense focus and drift. Never what you type, only the rhythm.
No account, no cloud. Every sensor is yours to switch off, or run the whole thing with none of them. Read the security page →
Questions, answered.
Is Vayl really free?
Yes. It’s free in exchange for your feedback, for a limited time. You’ll need an account, but nothing to pay.
Does it record my screen?
No. Vayl draws light on top of your screen. It never captures or transmits what’s on it.
Do I need the camera on?
No. It’s off by default. Vayl works on screen and sound alone; the camera only adds real-time adaptation if you opt in, all processed locally.
Is it safe to look at?
Vayl runs gentle, low-contrast rhythms well clear of the harsh strobe range, with intensity you control. If you have photosensitive epilepsy or are flicker-sensitive, check with a clinician first.
Will it slow down my machine?
No. It’s a lightweight overlay built to sit quietly over editors, design tools, and browsers without getting in the way.
Can I use it without sound?
Yes. The visual layer carries a full session on its own. Sound deepens it but is never required.
Can I turn it off instantly?
One click or a hotkey. Vayl is built to disappear the moment you don’t want it.
