An AI that actually knows your cancer.
Willow learns your story — your diagnosis, labs, imaging notes, the medications you're on today and the ones you took last week, the name of your oncology nurse — and holds all of it in context, every time you ask.
Your full record, read and understood
Pathology reports, scan summaries, cycle plans, lab trends — pulled from your chart and translated into plain language, not acronyms.
Grounded in the newest oncology research
Built on the same generation of models powering the frontier, tuned on cancer-specific literature, and constantly checked against the latest NCCN guidelines.
Kind by design
Willow never catastrophizes and never guesses. When something needs a human, it tells you clearly — and offers to message your care team for you.
Stop juggling pill bottles and post-its.
Appointments, refills, pre-op instructions, rides to infusion — 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 that respect bad days. Willow reads every answer, spots patterns your care team would want to know about, and remembers how you felt last Tuesday.
Step 3 of 5 · takes about 90 seconds
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 shares them with 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 weekly summary of what mattered — and escalates in real time if something serious shows up.
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 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 can draft the message for you.
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.
Your data stays yours
End-to-end encrypted, HIPAA-compliant, never sold. You can export or delete everything, any day.
Written by oncologists
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 chart automatically
Connect once via your portal (Epic MyChart, Cerner) and Willow keeps labs, notes, and imaging up to date on its own.
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. No streaks you'll feel bad about breaking.
The stuff you're probably wondering.
