Sound familiar?
You’ve described your symptoms to three different doctors, and each one told you something different.
You’ve tracked with apps. But you’re still left wondering why your brain feels clear one week and foggy the next.
You know something is affecting how you think and feel.
You just want someone to help you connect the dots.
That is why Leni exists.
Meet Leni
A companion that knows your brain before you do.
leni is a personalized companion for your brain health. She learns your symptoms, remembers your history, and gives you clearer guidance over time.
She looks at the whole picture — hormones, sleep, stress, metabolism, relationships, caregiving, work, and life stage — so the guidance feels grounded, balanced, and relevant to your real life.
You have goals. Your brain has biology. Leni helps you work with both.
When you want a real person, leni connects you to a trained coach for a one-on-one video call.
Personalized
Leni builds a fuller picture of your health, your life, and your goals, so her guidance reflects what you actually need.

Human support
Book a video call with a trained brain health coach, right in the app.
Built for every stage
Your brain changes. Leni changes with it.
Whether you're navigating perimenopause, managing a complex cycle, supporting a pregnancy, or wanting to age with a healthy brain, leni has the context, knowledge, and care to help.
Perimenopause
Hot flashes, brain fog, mood shifts, irregular periods. Leni helps you understand what’s happening and gives you real options — not just ‘wait and see.’
Longevity beyond menopause
Brain health after menopause includes more than symptom management. Leni supports cognition, metabolic energy, cardiovascular health, bone health, sleep, mood, connection, purpose, and healthy aging.
Reproductive years
PCOS, endometriosis, irregular cycles, fertility questions. Leni goes deeper than cycle tracking — she helps you understand the why.
Pregnancy & postpartum
Hormones don’t pause during pregnancy — they surge. Leni supports you through the changes, and the fourth trimester too.
How leni works
Everything you need. Nothing you don't.
AI COMPANION
A conversation, not a form.
Leni asks how you’re feeling. You tell her. She listens, remembers, and responds with something actually useful — not a generic tip sheet. The longer you use leni, the better she knows you.
HEALTH COACH
When AI isn’t enough, a real person is.
Some things need a human. That’s why leni connects you to trained brain health coaches for a 30-minute video call, right in the app.
SYMPTOM TRACKING
Track it. Understand it. Change it.
A quick daily check-in tells leni how you’re really doing in under 60 seconds. She tracks your symptoms over time and surfaces patterns you can actually do something about.
LIFETIME HEALTH RECORD
A record that’s actually yours.
Every check-in, every action note, every insight leni has shared — stored securely in your lifetime health record. Bring it to your doctor.
ACTION CHECK-IN
A place to turn insight into action.
Leni offers a focused prompt each day — grounded in what you’ve been sharing. You name what’s happening, choose one next step, and leni helps you follow through with care.
What women are saying
“I have tracked symptoms before, but I have never had something help me connect sleep, stress, hormones, and brain fog in one place.”
— Sarah, 47
“The coaching call helped me understand that I was not failing at work. I was carrying an unsustainable level of cognitive and emotional load.”
— Rachel, 52
“Leni helped me notice that my focus and mood were changing most on high-stress, low-sleep weeks. That gave me something useful to discuss with my doctor.”
— Michelle, 45
