MindZone
You type what you need, like "45 minutes of deep focus". MindZone turns it into a session of sound, light and guided breathing that follows your brain's natural rhythms. Wear a smartwatch and it notices how rested you are and adjusts. Listen as calm background sound, or as music with a beat.A neuro-acoustic instrument that generates structured, multi-phase brainwave-entrainment audio. Each session layers binaural carriers, amplitude-modulated entrainment, and ambient synthesis into one continuous stereo render. It now adapts in real time to biometrics from a wearable, delivers sessions as audio, synchronised audio-visual, or a visual breath pacer, and can render either pure entrainment or a tempo-locked musical mix.You're about to test an early version of MindZone. You tell it what you need, it builds a session of sound, light and breathing for it, and your two lines of feedback after each session decide what we fix next. This page explains everything before you start.

Personalised sessions that adapt as you listen
Tell MindZone what you need and it creates a session using sound, light and guided breathing. When a wearable is connected, the session can respond to your heart rate and recovery while it plays.
Why personalised cognitive support matters now
Focus, sleep and stress are everyday problems for almost everyone. The apps people reach for play the same fixed audio for everyone. They don't know who you are, can't tell you why a track should work, and don't change while you listen.
Two things just changed. Wearables put real-time heart-rate and recovery data in everyone's pocket, and language models can finally read a person's situation and reason about what they need. MindZone sits where those two meet.
Four ways to use the same adaptive engine
Describe a goal or explain how the day is going. One engine creates the session and delivers it as sound, light, guided breathing, or a coordinated combination.
MindWave
Audio on its own, for focus, sleep, or winding down.
MindField
Sound and light together, perfectly in sync. Our strongest option for focus and learning.
MindSight
Light and breath lead, with audio optional, for winding down and resetting.
MindSync
Connect a watch or ring; sessions tune to your real-time recovery.
How MindZone creates and adapts each session
Transparent session design
Every session is defined by parameters and cited research. We can show how each phase was chosen and what it is intended to do.
Real-time biometric adaptation
Sessions can read live biometrics and adjust in real time. This allows the same request to produce a gentler or stronger session according to the listener's current state.
Systematic approach
One engine can render unlimited personalised sessions on a small server. It does not depend on licensed recordings or studio production for every new session.
Accessibility and usability
The interface uses clear language, restrained motion and Lexend typography to make the product easier to read and operate. The consumer experience will continue to be tested and refined as the project grows.
Research behind the system
The method rests on peer-reviewed neuroscience. Claims are kept modest and wellness-grade, not clinical.
- 40 Hz gamma stimulation entrains neural activity (Iaccarino et al., Nature 2016, GENUS).
- Auditory steady-state response: the brain phase-locks to an amplitude-modulated tone (Picton et al., 2003).
- Theta and gamma coupling organises working memory across a phase arc (Lisman & Jensen, Neuron 2013).
- Cyclic-sighing breath lowers arousal faster than passive attention (Balban et al., Cell Reports Medicine 2023).

How the project started and what comes next
This started with my own focus problem. I was reading everything I could find on productivity, and it kept leading back to the brain, so I went further into the neuroscience and the research on how sound and light shift brain states.
Then I looked at what people were already using. Almost all of it plays the same pre-made tracks for everyone. Nothing knew who was listening, and nothing changed while you used it. The part the science actually cares about, that the response is individual, was the part they skipped.
So I built something that starts from the person instead of a fixed track. It reads your situation, plans a session, renders it, and adjusts to your body as it plays. That prototype is live now, and it works. I've started a company to fund the next steps, which is why I'm raising.
The path from here, near to far:
- Into daily use. Get the closed-loop product in front of real users and learn what genuinely helps.
- Measured against EEG. Partner for instrument time so sessions are checked against real brain activity, not just inferred from a wearable.
- Toward evidence. Move select effects from wellness toward clinical validation, one careful study at a time.
- The long horizon. A dedicated headset, and eventually work alongside clinics on the conditions this research began with.
What funding will support
We're raising $100K to get the product into daily use, sharpen the biometric loop, and reach our first cohort of paying users.
- Product and first users. Harden the engine and bring the closed loop to the earliest paying cohort.
- Sharpen the loop. Turn live biometrics into measurably better sessions.
- First validation. Instrument time to check sessions against real brain activity.
If this is the kind of company you back, we'd love to talk.

Safety notice: photosensitivity
MindZone AI is an experimental cognitive optimization prototype. It is not a medical device, and its sessions are not clinical treatments. By participating in this free alpha, you acknowledge that the visual engine utilizes flickering light washes and agree to use it at your own risk.
If you, or anyone who can see your screen, have epilepsy or a history of seizures, do not take part. Gentle light washes are on by default; stronger flicker stays locked behind a separate in-app photosensitivity screening.
What you're testing
MindZone makes custom audio (and light, and breathing) sessions to help you focus, relax, or sleep. There are no pre-made tracks. Every session is built for you, from your own words.
- Say what you need. Type one line, like "45 minutes of deep focus" or "help me calm down before bed".
- Wait a little. MindZone composes your session from scratch: soft instruments with a gentle pulse underneath that your brain tends to follow along with.
- Press play and do your thing. Study, work, rest. Headphones make it work best.
- Four doors. The map in the next section shows where each one leads.

How testing works
The deal, in plain words:
- You get premium for life. Every channel, every future feature, free forever on your account.
- You start right away. One press of the button below creates your seat, with no password or email to type.
- After each session, tell us two lines. What you felt, what worked, what didn't. The next session unlocks once you do.
- We recognize this browser profile with a necessary cookie. It keeps one-click access stable even when your network changes. Another browser or cleared cookies creates a separate tester account. IP is kept with security, session, feedback and agreement records and is never used to decide account ownership. The full list is in the Privacy Policy.
What to write in your feedback
After each session we ask for a couple of lines. Honest beats polite. The most useful notes tell us:
- How you felt before and after. "Was stressed, felt calmer by the end" is perfect.
- What you were doing while it played. Studying, working, falling asleep.
- What the sound was like. Too loud, too dull, an annoying pulse, a nice ending. Anything you noticed.
- Anything odd. If it crashed, stalled, or felt wrong, say so. That's the most valuable note of all.
Start testing
There's nothing to fill in. One press creates your tester seat and takes you straight in. This browser profile is recognized for one-click return visits. If you run a team, class or organisation and would like a separate testing group, write to aioraownr@gmail.com.
That one press is also your agreement: you've read the safety notice above, you're 13 or older (under 18 with a parent or guardian's OK), and MindZone may set necessary login and browser-profile cookies and store your sessions, feedback, IP and browser information while the alpha runs. Do not copy, share, forge or deliberately rotate the browser cookie: it is your account-continuity credential. Privacy & Terms.
Abstract
MindZone turns a plain-language description of a cognitive goal into a structured, multi-phase brainwave entrainment session. NVIDIA Nemotron 3 Ultra (via NVIDIA NIM) reads the request and writes a strategy specification: a sequence of phases, each set by its target brainwave band, entrainment frequency, carrier offset, timbre, and breath cadence. A deterministic heuristic planner remains as the offline fallback. A signal-processing pipeline then renders that specification into one continuous stereo file, using additive synthesis, binaural carriers, sinusoidal amplitude modulation, convolution reverb, and a noise bed tuned for stochastic resonance.
The design draws on published work: the 40 Hz GENUS protocol (Iaccarino et al., 2016, Nature), the auditory steady-state response (Picton et al., 2003), and the theta-gamma cross-frequency coupling described by Lisman & Jensen (2013). A session follows a phase arc, moving deliberately between bands instead of holding one fixed tone, so the stimulus tracks the cognitive task rather than working against it.
This page covers the architecture, the science it rests on, how to run a session, and the full parameter reference. The live instrument is open to alpha testers at mindzone.cloud/meta. You can play a thirty-second rendered sample below without signing in (§ 06).
Architecture
Theoretical basis
Auditory steady-state response (ASSR)
Amplitude-modulating a carrier at frequency f produces a phase-locked cortical response at the same frequency, measurable on an EEG. It is how an audible session can entrain a target band.
EVIDENCE: STRONG
40 Hz GENUS protocol
Combined audio-visual stimulation at 40 Hz drives gamma across cortex and hippocampus and improves cognitive markers in animal models. The basis for MindZone's learning-oriented gamma phases.
EVIDENCE: STRONG (animal)
Binaural beats & the frequency-following response
Two carriers offset by Δf presented dichotically produce a perceived beat at Δf. The effect requires headphones and is weaker than monaural AM, so MindZone keeps binaural carriers ≥20 dB below the foundation pad.
EVIDENCE: MODERATE
Theta-gamma cross-frequency coupling
Working memory appears organised by gamma cycles nested within a theta rhythm. Sessions therefore couple bands across a phase arc rather than holding a single frequency, mirroring this nesting.
EVIDENCE: STRONG
Alpha entrainment & attentional gating
Alpha-band activity (8–12 Hz) indexes inhibitory attentional control. Relaxed-focus and creative phases target this band to lower distractibility without forcing high arousal.
EVIDENCE: MODERATE
Stochastic resonance
A calibrated noise floor can raise the detectability of a sub-threshold periodic signal. The pink/brown noise bed is set to support the entrainment envelope, not to mask it.
EVIDENCE: MODERATE
Slow-wave sleep & acoustic enhancement
Sound delivered in phase with slow oscillations during deep sleep can enhance slow-wave activity and memory retention. Informs the delta-targeted descent of sleep sessions.
EVIDENCE: MODERATE
Sleep spindles & consolidation
Delta and spindle activity during NREM sleep support memory consolidation. Sleep phases prioritise an unbroken descent through theta into delta over any audible novelty.
EVIDENCE: STRONG
Isochronic amplitude modulation
Pulsing a tone on and off gives a stronger entrainment envelope than binaural beats, and it works on speakers. MindZone uses a sinusoidal AM shape, never a square one, capped at 0.10 depth so the pulse never turns alarm-like.
EVIDENCE: MODERATE
Melanopsin & non-visual light response
Intrinsically photosensitive retinal ganglion cells respond to light colour and intensity, shaping alertness and circadian state. The visual engine maps colour temperature per band on this basis.
EVIDENCE: MODERATE
Empirical aesthetics of acoustic stimuli
Perceived pleasantness of a stimulus modulates engagement and tolerance over a long session. Timbre, reverb, and humanised timing are tuned so a session is bearable for its full duration.
EVIDENCE: AESTHETIC
Cyclic-sighing breath pacing
Extended-exhale breathing lowers physiological arousal faster than passive attention. MindSight's breath pacer drives an inhale/exhale ratio matched to the target state.
EVIDENCE: EXPLORATORY
Reading-friendly typography (Lexend)
The interface is set in Lexend, a typeface designed and measured to raise reading proficiency: widened default spacing improves reading speed and lowers effort for readers with dyslexia or attention and focus difficulties. It carries into the consumer product. This build is a research prototype; the full interface is rebuilt for consumers after more research, team growth, and engine work.
EVIDENCE: APPLIED
