What students say

What med students are telling us.

I have been using Nabu to study for my shelf exams, and it has been a great resource for me. I especially appreciate how it breaks down complex information in a way that is easy to understand.
★★★★★ Tiffany MS3
Nabu Tutor has been an incredibly valuable tool for me as a medical student. It explains concepts quickly and precisely, while using a dialectic format that pushes me to think critically and consolidate my knowledge. Compared with other AI tools I have used, Nabu feels much better tailored to medical education, with a stronger medical knowledge base and a more effective approach to learning. I have noticed a clear improvement in both my understanding of difficult concepts and my practice test performance, and I would highly recommend it to other medical students.
★★★★★ Paul MS3
I found Nabu to be an excellent way to receive tutoring without having to worry about the high costs or availability constraints that hiring a live tutor may have. The service was helpful and served as a great supportive tool in understanding and learning about different medical topics.
★★★★★ Matthew MS2
Nabu is a great tool for conversational tutoring and can be seamlessly integrated with my other study resources. Having it on in the background and being able to view my screen makes it so easy to ask for explanations when I'm doing practice questions.
★★★★★ Seth MS4
I used Nabu Tutor in conjunction with question banks as I was studying for Step 1. Sometimes the explanations after doing questions don't help me understand as much as I need it to, so I am grateful that Nabu can explain things in a way that makes sense for me, even if I have to instruct it to “dumb it down.” I appreciate the fact that it is well-versed on what is high yield for the Step exams, feeding me only information that is relevant. The ability to share my screen, have a voice conversation with it, and receive live answers saves me valuable time that I could dedicate to reviewing questions instead of transcribing information to ask. I look forward to using this platform for my clinical Shelf exams and Step 2.

How it teaches

It doesn't hand you the answer. It teaches you to find it.

Most tools give you a fact and move on. Nabu works the case the way a good attending teaches on rounds, asking the next question, waiting for you, and showing its reasoning so the why sticks long after the answer would have.

Example session

Why spironolactone and not furosemide for this cirrhotic with ascites?
Let's reason it out. In cirrhosis, what's actually driving the fluid retention? Think about the hormones.
…secondary hyperaldosteronism?
Exactly. So if aldosterone is the culprit, where do you want to act? Spironolactone blocks it right at the distal tubule; furosemide works upstream and can push the RAAS up even further. That's why it's first-line here. Want to try the electrolyte trade-offs next?

Why this matters

Step 1 is harder to pass than it used to be.

First-time pass rates have been sliding for years. Nabu helps you train the way the exam actually tests you, reasoning through cases as if you're already on the wards, so you study smarter, not just longer.

Why Nabu

Built different. Not just another study app.

Most tools give you content. Nabu gives you a tutor that knows medicine, knows you, and has a real physician in your corner.

Getting started

How we'll get you through med school.

01

Tell it where you're headed

Pick your exam and your date. Nabu turns the syllabus into a calm, weekly plan instead of an endless question bank.

02

Learn by reasoning out loud

Work through real cases with a tutor that explains the thinking, tuned to your level. No generic flashcards, no boring lectures.

03

Stay on track, without the dread

Gentle nudges and an honest picture of your progress keep the momentum going, and a real doctor is there each week if you're stuck.

Real doctors, not just software

Doctors in your corner, every single week.

Nabu is patient enough to teach you at 2 a.m. But the part that actually gets you across the line is human: every paid plan includes live office hours with a physician who scored 275+ on Step 2 CK, and Pro adds a monthly one-on-one with a resident physician who has sat exactly where you're sitting.

Why we built this

We're physicians and an engineer who got tired of watching good people drown in question banks. Nabu is the tutor we wish we'd had: one that teaches the reasoning, not just the answer, and puts a real doctor in your corner every week. If that's the kind of help you're looking for, we'd love for you to try it.

Questions, answered plainly

The things students actually ask.

Yes. Every paid plan includes live, weekly group office hours with a physician who scored 275+ on Step 2 CK. Pro adds a monthly 30-minute one-on-one with a resident physician, for tutoring, career advice, or whatever's on your mind.
It can be. Many students get further with Nabu alone. Others use it alongside a tutor to cut the hours (and the cost). Either way, you still get a real physician each week.
USMLE Step 1, Step 2 CK and Step 3, COMLEX, and your med-school course exams.
Yes. Plans can be cancelled before the 5th of the new month, no questions asked.
Your study data is encrypted in transit and at rest, and we never sell your personal information.
