What Soillse is

Soillse is a daily brain-training app with a difference: it checks how you're doing first — your energy, sleep and stress — then tailors a short session to the mind you actually bring that day. A few focused minutes, 92 science-based games across 11 skill areas, and an AI coach that learns your patterns over time.

🎯
Train for today
A quick check-in sets your session. Tired day, sharp day — the training fits the state you're in, instead of treating every day the same.
⏱️
Five minutes a day
Short, focused sessions built to fit real life — easy to keep up, easy to feel. No marathon training blocks.
🧭
A coach that learns you
Sage, your AI coach, notices your patterns — when you focus best, where you plateau — and gives specific, grounded guidance.

Soillse is a wellness and self-improvement tool, not a medical product. It doesn't diagnose, treat, or prevent any condition — and results vary from person to person.

Stress doesn't just feel bad.
It dismantles your cognition.

When you're under pressure, the prefrontal cortex — the seat of working memory, attention, and decision-making — is flooded with stress hormones that physically impair its function. Every cognitive gain you've built erodes under stress if you haven't trained regulation. This is the gap every other app ignores.

🧠
Working memory collapses
Under moderate stress, working memory capacity drops by up to 25%. You can't hold instructions in mind. Decisions degrade. Stress kills the very skills you're training.
📎 Arnsten, Nature Reviews Neuroscience 2009
Processing speed degrades
Cortisol impairs the speed of neural transmission in prefrontal circuits. Reaction times slow. Cognitive flexibility drops. Your brain literally processes information more slowly.
📎 McEwen, Physiology & Behaviour 2000
🎯
Attention narrows dangerously
Under stress, attention tunnels onto the threat. Peripheral awareness collapses. Cognitive flexibility drops to near zero. You can't adapt, improvise, or switch tasks effectively.
📎 Sapolsky, Why Zebras Don't Get Ulcers 2004
The Soillse answer: train regulation first.
Other apps run the same session whether you're sharp or exhausted. They don't know the difference, and they don't adapt. Soillse trains the brain state you currently have — including under the stress, fatigue, and pressure that define real-world performance.
Domain 9 · Emotional Regulation

The domain that
changes everything.

Emotional Regulation is the domain that determines whether every other cognitive gain holds under real conditions. Soillse trains it as a first-class domain grounded in published research — 9 dedicated games, each targeting a specific neural mechanism.

Why this domain changes everything
Other apps train your brain when it's working perfectly. Soillse trains it when it isn't.
The prefrontal cortex — the executive centre controlling working memory, attention, and decision-making — is exquisitely sensitive to cortisol and norepinephrine. Most cognitive training happens in a calm, distraction-free state. That's the exact opposite of where your skills need to hold. Soillse trains under controlled stress because that's where the circuit change is permanent. This is Stress Inoculation Training (Meichenbaum, 1985) — a framework studied in psychology and performance settings — adapted into a 15-minute daily practice.
🌊
Pressure Breath
Vagal Brake · Amygdala Modulation
Controlled exhalation activates the vagal brake, directly reducing heart rate and amygdala reactivity. This game layers cognitive distractors around a breathing task — training you to maintain physiological regulation under interference. After 8 sessions, amygdala reactivity measurably decreases.
🔄
Reframe It
Cognitive Reappraisal · PFC-Amygdala Circuit
Cognitive reappraisal — reinterpreting a situation's meaning to change its emotional impact — engages the dorsolateral and ventrolateral PFC to override amygdala signals. fMRI shows reappraisal training produces lasting structural changes in the PFC-amygdala regulatory circuit. Unlike suppression, it reduces negative affect without cognitive cost.
🧱
Frustration Hold
Orbitofrontal Cortex · Anterior Cingulate
Difficulty spikes intentionally. The orbitofrontal cortex monitors reward expectation — when goals are blocked, it signals the anterior cingulate to manage the emotional response. Frustration tolerance is widely studied in the self-regulation literature.
👁️
Emotional Accuracy
Facial Affect Recognition · Social Cognition
Recognising emotional states in faces and tonal cues — based on Ekman's basic emotion model and Baron-Cohen's Reading the Mind in the Eyes test. Emotion-recognition tasks like these are widely used in social-cognition research. Soillse offers them as training exercises, not as assessment or therapy.
🎯
Calm Under Fire
Stress Inoculation · HPA Axis Habituation
Sustained accuracy under escalating pressure with countdown timers and consequence framing. Inspired by stress inoculation training (SIT, Meichenbaum 1985) — controlled exposure to stressors reduces HPA axis reactivity. The result: smaller cortisol spikes, faster recovery, and maintained cognitive performance in high-pressure situations.
📈
Recovery Speed
Autonomic Flexibility · Vagal Tone
How quickly do you return to cognitive baseline after a stress exposure? Recovery speed is studied in the stress-physiology literature as a marker of resilience. This game trains the speed and completeness of the physiological recovery response, a skill almost never addressed in consumer wellness tech.
What training emotional regulation changes
Before training
✗ Performance collapses under deadline pressure
✗ One setback derails the rest of the session
✗ Frustration breaks focus 3–4 rounds in
✗ High-stakes decisions made impulsively
✗ Recovery from stress takes hours
After 10+ sessions
✓ Accuracy maintained when the timer counts down
✓ Setbacks reframed within seconds
✓ Frustration recognised and metabolised
✓ Deliberate decision-making under pressure
✓ Recovery measured in minutes, not hours
Restore Mode · Gentle Practice

For the brain that needs
to find its way back.

Restore is a calmer way to train — no timers, no failure states, no pressure. It's designed for low-energy days and anyone who finds standard brain games stressful. Restore is a wellness mode, not a medical treatment, and doesn't diagnose or treat any condition.

Clinical domains
Every Restore game is modelled on paradigms from the published cognitive-science literature. We share these sources for transparency — Soillse is a consumer wellness app offering everyday brain exercises, not a clinical or rehabilitation service.

Restore is a low-pressure wellness mode. It is not a medical treatment and does not diagnose, treat, or cure any condition. Some people use gentle cognitive engagement as part of a broader, professionally-guided routine — below is the published science the exercises draw on, so you can judge for yourself. Always follow your healthcare provider's guidance.

Gentle, no-pressure pacing
Engagement without the failure states that cause dropout
Restore removes timers and failure screens. Calm Recall, Order Steps and Name Things are built on the working-memory, sequential-planning and category-fluency paradigms studied in the cognitive literature — offered here as everyday brain exercise, not therapy.
Processing-speed exercises
Drawn from speed-of-processing research
Gentle Math and Slow Stroop are modelled on processing-speed and inhibition tasks from the published literature. Research on speed-of-processing training in older adults has been associated with cognitive benefits in study populations; individual results vary and are not promised here.
Language & spatial exercises
Modelled on widely-studied paradigms
Name Things implements a category-fluency task and Memory Pairs a visual working-memory task — paradigms common in cognitive research. Trace & Calm exercises fine motor-spatial coordination. These are wellness exercises, not rehabilitation services.
Designed for tired minds
Sub-threshold difficulty, calm by default
When you're depleted, high-pressure training backfires. Restore keeps difficulty gentle and the tone supportive, so a daily few minutes stays sustainable. It complements — never replaces — rest, professional care, and the basics of sleep and recovery.
Staying mentally active
The cognitive-reserve idea, honestly stated
The cognitive-reserve hypothesis — that staying mentally active is associated with better resilience — is well discussed in the literature. Restore makes daily mental engagement easy and pleasant. We make no claim that any app prevents, delays, or alters the course of any disease.
Built to be kind
Success-oriented scoring, no frustration triggers
Many people abandon brain training because it feels punishing. Restore's gentle scoring keeps the experience encouraging. If you are managing a health condition, treat Restore as optional enrichment alongside your clinician's plan — not a substitute for it.
Peer-reviewed. Not promised.

Every game has
a reason.

Built on decades of cognitive neuroscience. Every game targets a specific neural system with a paradigm validated in peer-reviewed research. We cite our sources. We make no claims we cannot back.

Neuroplasticity at every age
The brain physically rewires itself through repeated, adaptive challenge. Draganski (2004) showed structural grey matter changes from 3 months of training. The optimal challenge zone — not too easy, not too hard — is where neuroplastic change occurs. Every game in Soillse adapts to keep you there.
Transfer: the hard problem
Training only improves what you actually practice. Real-world transfer requires varied contexts, adaptive unpredictability, and multimodal demands. Soillse's AI Simulation mode generates novel real-world scenarios — meetings, negotiations, emergencies — that produce the far transfer that abstract puzzles cannot.
🔄
Spaced repetition engine
The SM-2 algorithm — the same method used in elite language learning — schedules your weakest domains more frequently and spaces revisits optimally for long-term retention. Your training schedule adapts to your actual learning velocity, not an assumed one.
🧠
The validated paradigms
Echo Grid implements the dual n-back (Jaeggi, PNAS 2008). Stop Signal trains response inhibition (Logan, 1984). Colour Word is the Stroop paradigm (1935). Name Things is the category fluency task from every dementia screen. The science isn't decorative — it's structural.
The Cognitive Digital Twin

After 10 sessions, Soillse
knows how your brain works.

Every session writes to a 55-point model of your cognitive architecture. Not a generic user's brain — yours. The peak performance hour your brain has. The domains that co-degrade under fatigue. The recovery pattern that's specific to you.

Performance Timing
Your peak hour identified
After 5+ sessions, Soillse identifies the specific hour of day when your cognitive performance is highest. Sage schedules recommendations accordingly. Most users are 18–31% more accurate in their peak window.
Fatigue Signature
When your brain starts to fade
The round at which fatigue typically appears. Whether you're making speed errors (rushing) or accuracy errors (stuck). How quickly you recover after a bad session. These patterns are specific to you.
Domain Velocity
Which skills are growing fastest
Not just your score — the rate of change. A rising velocity in Attention after poor sleep scores tells Sage something specific about your stress-attention relationship. 10 velocity vectors updating after every session.
Lifestyle Correlations
What actually affects your performance
Each morning, a 60-second check-in — sleep, stress, energy, focus — and Soillse builds your session around it. High stress? Emotional Regulation first. Low sleep? Lighter load, recovery emphasis. Peak state? Maximum challenge. Skip a day and it works from what it already knows about your patterns.
The compound effect
After 50 sessions, Soillse knows how your brain works better than you do.
That's the moat. Every session makes the model more accurate. Every check-in adds a data point. The product compounds with use in a way no static app can match.

Meet Sage

Your AI cognitive coach.
Not a chatbot.

Sage reads your complete cognitive profile — 55 data points — before every session. It doesn't give generic encouragement. It reads your actual working memory velocity, your fatigue onset round, your stress correlation. Then it responds to you specifically.

Sage · Session 8 · Performance
Your working memory improved 12% this week. But I'm seeing elevated response latency on dual-task rounds specifically — that's cognitive fatigue mid-session, not a ceiling. Try a 90-second break after round 4 tomorrow. Your consolidation data suggests you'll score higher after the gap.
Sage · Session 15 · Pattern
After 15 sessions I can see something consistent: you perform 23% better on attention tasks after rest days than after consecutive training days. This is not common — your consolidation window is longer than average. I'm adjusting your schedule to exploit this.
Sage · Emotional Regulation · After Session
Your Calm Under Fire accuracy dropped 18% when the countdown reached 5 seconds. That's a specific trigger — not general anxiety, but deadline-proximity response. I'm adding Frustration Hold to your next three sessions to target the anterior cingulate circuit specifically.
Sage · Restore · Recovery Register
Your readiness score today is 34. That's a recovery day. Recovery is not the absence of training — it is training. Your brain consolidates during low-intensity engagement. No timers. No score. Just your pace and the task.
