An AI partner that knows your cancer experience
Meet HopeAI, the partner built for questions that keep you up at night. This isn’t just a chatbot that read some medical websites — it’s grounded in physician reviewed content, and trusted by thousands of patients.
Chat with Hope
By patients, for patients · Secure and private · Clinically reviewed
These are the questions patients actually ask
Not “what is cancer?” — it’s the real questions that come at 2am, after the appointment, when you're trying to make sense of what just happened.
"What should I even ask at my appointment tomorrow?"
‒ K (52, Breast Cancer Patient)
"I just need to talk through what I’m feeling"
‒ L (71, Metastatic Breast Cancer)
"I got my pathology report back and I don't understand any of it."
‒ S (47, Triple Negative Breast Cancer)
This is what support looks like at 2am
No intake forms. No waiting rooms. Just answers for whatever is on your mind.
3 ways patients use HopeAI every day
From treatment decisions to emotional support — HopeAI helps with the moments that matter most.
Treatment options
You're choosing between a lumpectomy and mastectomy, weighing what your surgeon said against what you read online at midnight. HopeAI helps you sort through the trade-offs and figure out what to ask before you decide.
Symptom tracking
Your joints ache and you're not sure if it's the medication or something worse. HopeAI helps you log what's happening, understand the context for your symptom.
Appointment prep
You have 15 minutes with your oncologist tomorrow and a hundred thoughts swirling. HopeAI helps you walk in prepared with the questions that matter, so you’re not left wondering what you forgot in the parking lot after.
Visualize where you are in your experience
No other AI shows you this. Our Cancer Map shows every path and station in your experience — and gives you the support you need at each one. What to expect, what to ask, what comes next. Built by patients, reviewed by oncologists.
Built for cancer, not just health
HopeAI isn't a standalone chatbot — it's part of Manta Cares, a suite of powerful tools built by patients, for patients.
Make your choice
We're not assigned by your payer or pushed by your provider. You found us, and we’re ready to help.
Navigate the map
Our Cancer Maps help you see what’s coming, get oriented, and navigate your many decisions confidently.
Get the specifics
HopeAI draws from physician-reviewed cancer content. It’s reliable and contextual, not generic health information.
Find more tools
HopeAI works together with our symptom tracker, appointment notebook, and cancer map.
Designed for vulnerable moments
Cancer patients are going through one of the hardest experiences of their lives. HopeAI is built with that weight in mind.
Physician reviewed content
Every response draws from content reviewed by our clinical team, led by Dr. Doug Blayney — former director of the Stanford Cancer Center and past ASCO president.
Support, not replacement
HopeAI doesn’t diagnose, prescribe, or replace your oncologist — it helps you show up prepared for your upcoming conversations, not skip them.
By people who've been there
