An AI that actually knows your breast cancer.
Willow learns your story: your subtype, whether HR-positive, HER2-positive or triple-negative, your labs, imaging notes, the medications you're on today and the ones you took last week, the name of your oncology nurse. It holds all of it in context, every time you ask.
Your full record, read and understood
Pathology reports, receptor status, scan summaries, cycle plans, lab trends: pulled from your records and translated into plain language, not acronyms.
Grounded in breast cancer research
Willow searches PubMed and ClinicalTrials.gov for your subtype and treatment phase, cites every source, and says so plainly when the evidence is thin.
Kind by design
Willow never catastrophizes and never guesses. When something needs a human, it tells you clearly and helps you bring it to your care team.
Stop juggling pill bottles and post-its.
Infusion days, surgery dates, radiation sessions, refills and pre-op instructions: Willow keeps the whole calendar in its head and nudges you only when you actually need to act.
Everything lined up for Wednesday.
No decisions to make before bed. Willow has the plan. You just have to show up.
I'll keep your pill schedule in my head.
Every dose tracked, every refill ordered before you run out. If something looks off, I'll flag it.
I'll talk to the front desk for you.
Willow drafts messages to your care team, reschedules when life happens, and makes sure prep instructions arrive before you need them.
Two minutes a day, and we've got the full picture.
Short, tender check-ins built around breast cancer treatment: the nausea, the fatigue, the tingling hands, the fever that needs a call. Willow reads every answer, spots patterns your care team would want to know about, and remembers how you felt last Tuesday.

How are you feeling today?
Anything bothering you? (tap all that apply)
Designed around bad days
Every question is optional. Tap a number, tap some tags, done. If you want to talk it through instead, the answer box accepts voice or text.
Willow notices the patterns
Three rough nights in a row? A new side effect appearing on day 5 of every cycle? Willow connects the dots and puts them in front of your care team before your next visit.
Your care team gets a heads up, not a pile
Instead of dumping every answer into their inbox, Willow writes a short summary of what mattered between visits, and tells you clearly when something needs a call today.
Your heart rate. Your sleep. Already in the story.
Willow connects to the devices you already wear. No new gadget to charge, no extra app to check. The vitals just show up alongside your labs and your check-ins.
Fitbit is live today.
Heart rate, resting rate, steps, sleep stages, and HRV, all stitched into your dashboard automatically.
Apple Health is next.
If you live in the Watch, you'll be home. We're wiring in SpO₂, ECG, cycle tracking, fall detection, and mindful minutes, everything your Watch already knows.
The 3 am “is this normal?”, finally answered.
No more Googling “paclitaxel tingling” at midnight. Willow already knows your subtype, what cycle you're on, what drugs you're taking, and what your last bloodwork looked like, so the answers are actually yours.
Willow always tells you when it's confident, when it's guessing, and when something needs a real doctor, and it helps you write the question down for your next visit.
My oncologist gave me a 40-page binder. Willow read all of it, answered my late-night questions in plain English, and reminded me to drink water. It’s the first time through chemo I haven’t felt like I was the only one keeping track.
Things we take seriously.

Every guideline Willow uses is reviewed by practicing oncology clinicians. When evidence is thin, Willow says so.
Shares with your care team
One-tap summaries to oncology, primary care, or family. They stay in the loop; you stop being the middleman.
Reads your records for you
Upload a PDF, a photo of a paper page or a scan, and Willow pulls out receptor status, labs, medications and appointments, and keeps them searchable.
Free if you need it to be
Cancer is expensive enough. We offer financial assistance, no awkward conversation required.
Warm, never pushy
Willow asks how you are. It doesn't gamify or guilt-trip, and there are no streaks you'll feel bad about breaking.
