The gap

You feel it before
you can name it.

Tired in a way sleep doesn't fix. Wired but unable to focus. Disconnected from yourself, or from people you care about. Something is off — but most wellness apps weren't built to see it.

They track steps. They celebrate streaks. They tell you to meditate. But they don't connect the signals — and they don't tell you why.

Nurii does.

Four meetings, no break since 8am
Nurii reads your calendar. Your nervous system has been in stress mode all morning — and your afternoon will suffer for it without intervention.
Sleep slipping every Monday
No single data point shows this. Nurii tracks it across weeks and connects it to your weekend rhythm before it quietly compounds.
Eight days without a real connection
Human connection is one of the strongest predictors of brain longevity. Nurii notices when it's been too long — and makes the next step simple.
Six days without journaling
Last time you went this long, your mood dipped by mid-week. The pattern is there — and a three-minute prompt is waiting.

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.

Nurii notices
It's 1pm. You've had four meetings and haven't moved since 8am. Five minutes of somatic movement will reset your nervous system before the afternoon runs away.

01
Read
Nurii reads your calendar, habits, sleep and movement — building a picture of your day in real time.
02
Notice
The AI connects patterns across your pillars — spotting what matters right now, before you do.
03
Nudge
One calm, specific suggestion — with the reason it's appearing right now. One next step. Never a list.
04
Compound
The session completes, progress updates. Over weeks, small consistent actions quietly shift your baseline.

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.

01
Breathwork
Regulate your nervous system in minutes. Matched to your day.
02
Somatics
Release tension stored in the body before it becomes chronic.
03
Sleep
The brain's clean-up cycle. Everything else is built on this.
04
Neuroplasticity
Wire new pathways daily through small, deliberate habit shifts.
05
Nutrition
Food is your most direct lever. Brain foods, simply explained.
06
Journaling
Three minutes of honest writing changes your brain chemistry.
07
Connections
Human connection is the strongest predictor of a long, healthy brain.
08
Movement
Resistance, somatic, yoga — found near you, matched to your day.

The science behind it

35%
reduction in dementia risk from an anti-inflammatory, high-fibre diet. The foods that reduce brain inflammation are the same ones that protect cognitive function over decades.
New England Journal of Medicine · 2023
23%
lower cortisol — the primary driver of cognitive decline — in people who practise regular meditation and gratitude. Chronic stress shrinks the hippocampus. Calm protects it.
Psychoneuroendocrinology · 2021
2×
greater BDNF (brain-derived neurotrophic factor) in people who combine resistance training with somatic movement. BDNF is the protein that grows new neural connections.
Journal of Physiology · 2022
47%
of people who learn one new small skill per week — a different route, brushing teeth with the other hand — show measurable improvements in memory and cognitive flexibility within 8 weeks.
Nature Neuroscience · 2020
3 min
of daily journaling produces lasting wellbeing gains six months later. Writing externalises rumination, activates the prefrontal cortex, and raises serotonin simultaneously.

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."
