Wearable Intelligence for overlooked brains.
Every neurodivergent brain runs on its own rhythm: your cycle, your neurotype, and how they interact.
Olai tracks that in real time, so you can finally work with your brain instead of against it.
Women's hormonal cycles produce measurable shifts in brain chemistry, cognition, and physical capacity.
For women with ADHD, autism, and related neurotypes, these rhythms interact with existing neurological patterns in ways that shape focus, energy, and emotional regulation. These interactions have rarely been studied and almost never measured in real time.
The result is a medical system built on an incomplete picture of human biology.
Clinical Trial Representation
Women make up only 40% of clinical trial participants - despite comprising half the global population. The research baseline was never built forus.
Harvard Medical School, 2022
Adverse Drug Reactions
Women experience adverse drug reactions at twice the rate of men across 76 of 86 drugs studied. This is what happens when dosing is calibrated to a body that isn't yours.

Wearables Built For This
Not one consumer wearable accounts for hormonal cycle phase or neurological diversity in its health algorithms. Every insight it gives you was designed for someone else.
Your brain. Your cycle.
Finally visible.
The research linking hormonal cycles to brain state has existed for decades. What has never existed is a tool that translates it, making that science visible, personal, and actionable in real time.
Real-time State Monitoring
Multimodal EEG capture across the brain regions that govern focus, emotion, and cognition.
Hormonal Cycle Intelligence
Hormonal phase data mapped directly to your neural signals — context your brain has always had, now made visible.
Built for Neurodivergent Brains
Algorithms built around ADHD and autistic neurotypes, accounting for the ways neurodivergent brains interact with hormonal shifts differently.
This isn't a theory. It's documented.

The cycling brain
Decades of research show that hormonal cycles shape whole‑brain network dynamics, connectivity, and signal complexity across the month.
Neurodivergence in a cycling system
For people already managing conditions like ADHD and anxiety, these hormone‑linked brain shifts can amplify swings in focus, overwhelm, and emotional regulation from week to week.
Cognition and executive function
Estradiol around ovulation is associated with increased activation in hippocampal and prefrontal regions that support memory, planning, and complex problem‑solving.
The data gap
Most clinical studies, datasets, and algorithms still under‑represent women and rarely model menstrual phase, meaning many digital health tools are trained on male‑dominant or cycle‑blind data.
Emotion and stress reactivity
In the luteal phase, higher progesterone is linked to stronger fronto‑striatal and amygdala responses, altering emotional sensitivity, motivation, and stress and threat processing.
Where Olai comes in
Olai builds directly on this evidence base, translating hormone‑driven changes in brain state into real‑time, cycle‑aware support instead of one‑size‑fits‑all tracking.
You were never the problem.
The data was.
