nurii – nurii's landing page

Built around you

Women and men don't age the same way. Nurii doesn't treat you the same way.

When you sign up, you tell Nurii about yourself — your biology, your cycle or hormonal profile, your goals. From there, the AI adapts. Not just the content, but the recommendations themselves.

For women

Cycle-aware guidance, every week of the month

Cold exposure should be shorter and less intense across the luteal phase — the hormonal and cardiovascular response differs significantly. Fasting windows that optimise a man's metabolism can spike cortisol in women and disrupt reproductive hormones. Nurii prompts you based on where you are in your cycle.

Cycle-aware eating Recovery timing Cold exposure Breathwork phases

For men

Hormone-optimised nudges from your 30s onward

Testosterone declines from the mid-30s — affecting energy, mood, sleep quality, and cognitive sharpness long before most men notice. Fasting windows, resistance training timing, and sleep architecture have an outsized impact on maintaining healthy testosterone and cortisol balance. Nurii tracks and nudges around these specifically.

Fasting windows Training timing Sleep architecture Cortisol balance

Set up once. Adapt forever. Input your data on sign-up and Nurii's AI adjusts every recommendation — nudges, nutrition, movement, and recovery — to your biology. Both change with age. Nurii adapts as you do.

Personalised from day one

The AI loop

The nudge that explains itself.

Nurii doesn't just tell you what to do. It tells you why — using context it already has from your day, your habits and your calendar.

Your cortisol is likely elevated — you've had back-to-back stress since this morning. Here's what helps:

Read

Calendar, habits, sleep and movement — your day in real time.

Notice

The AI connects patterns across your pillars before you do.

Nudge

One calm suggestion with the reason it's appearing. Never a list.

Compound

Small consistent actions quietly shift your baseline over weeks.

Connect a wearable to go deeper. Nurii works from day one using your calendar, phone data and self-reported habits. Add Apple Health, Oura or Whoop to bring in sleep quality and heart rate data for a richer picture.

The framework

Eight pillars.
One brain.

Nurii tracks the eight areas that shape your brain health and nervous system — keeping them balanced, so you don't have to think about it.

Breathwork

Regulate your nervous system in minutes. Matched to your day.

40% reduction in anxiety symptoms after 8 weeks of consistent breathwork — improving mood, focus, and nervous system resilience. Journal of Clinical Psychology · 2021

Stress & Cortisol

Chronic stress shrinks the hippocampus. Learn to recognise and reduce it.

2.5× more likely to develop dementia in adults with chronically elevated cortisol — even decades before any symptoms appear. Neurology · 2010

Sleep

The brain's clean-up cycle. Everything else is built on this.

60% more metabolic waste — including proteins linked to Alzheimer's — cleared from the brain during deep sleep than during waking rest. Science · 2013

Neuroplasticity

Wire new pathways daily through small, deliberate habit shifts.

47% of people learning one small new skill weekly show measurable improvements in memory and cognitive flexibility within 8 weeks. Nature Neuroscience · 2020

Nutrition

Food is your most direct lever. Brain foods, simply explained.

36% lower risk of Alzheimer's in people who consistently follow a brain-healthy MIND diet — rich in leafy greens, berries, and omega-3s. Alzheimer's & Dementia · 2015

Journaling

Three minutes of honest writing changes your brain chemistry.

3 min of daily journaling produces lasting wellbeing gains six months later — activating the prefrontal cortex and raising serotonin simultaneously. Journal of Positive Psychology · 2021

Connections

Human connection is the strongest predictor of a long, healthy brain.

64% higher dementia risk in chronically lonely adults — social connection is as vital to brain health as sleep and exercise. PLOS Medicine · 2023

Movement

Resistance, somatic, yoga — found near you, matched to your day.

2× greater BDNF — the protein that grows new neural connections — in people who combine resistance training with somatic movement. Journal of Physiology · 2022

Why this matters

We don't have a cure. But we have decades of evidence about what slows it down.

Dementia doesn't arrive suddenly. The biological changes that lead to cognitive decline often begin two to three decades before any symptom appears — quietly, in the background, while life carries on.

The research points clearly at the same variables: how you sleep, how you move, what you eat, how you manage stress, whether you feel genuinely connected. These aren't soft wellness ideas. They're the factors science has repeatedly linked to how well — and how long — your brain functions.

Nurii won't prevent dementia. No app can make that promise honestly. What it can do is help you act on the evidence that exists, consistently, before you need to.

"Most people don't think about brain health until something goes wrong. The research suggests we should start much earlier."

Nurii is built on the habits science links to healthier ageing — not a cure, but a meaningful start.

The evidence

35%

Reduction in dementia risk associated with an anti-inflammatory, high-fibre diet — the nutritional foundation Nurii is built on.

New England Journal of Medicine · 2023

60%

Higher dementia risk in people who are chronically socially isolated. Connection isn't a nice-to-have — it's protective.

The Lancet · 2020

4–5 yrs

Delay in Alzheimer's onset linked to consistent cognitive engagement — one of Nurii's neuroplasticity pillars.

Annals of Neurology · 2022

23%

Lower cortisol — the primary driver of cognitive decline — in people who practise regular breathwork and gratitude.

Psychoneuroendocrinology · 2021

Why Nurii exists

"I built Nurii because the research exists, the tools exist — but no one had connected them into something a person could actually use on a Tuesday morning."
