Your personal AI MCAT tutor.
PreMedulla learns how you think — your strengths, your weak spots, the error patterns you keep repeating — and runs the diagnosis and planning in the background, so your time goes to practicing, reasoning, and actually learning.
Early access. One email. No card, no account yet.
The work you shouldn't have to do.
Most self-studiers either burn hours every week on diagnosis, pattern-tracking, and deciding what to review next — or skip it and plateau. PreMedulla runs that work in the background.
-
Reads how you think, not just what you answered.
On every practice question and full-length section, PreMedulla looks at your reasoning, not just the bubble you filled.
-
Names the error and tracks the pattern.
It catalogs each miss against a real error taxonomy, then watches across passages and sections so the recurring patterns become visible.
-
Plans what you should review next.
The plan adapts to your error profile, not a generic calendar. You stop deciding what to study and start doing it.
-
Routes content gaps to the resources that already teach them.
When a miss is a knowledge gap, PreMedulla points you to the libraries that already do content well — instead of pretending to reteach the MCAT:
- Sketchy
- Khan Academy
- AnKing
- AK Lectures
You do the thinking. PreMedulla does the bookkeeping.
Built for self-studiers who can't drop $2,000 on a coach.
You're 8 to 12 weeks out from the MCAT. You're managing your own prep. You've watched the strategy videos and ground through the practice — and the score is moving slowly, or in one section it isn't moving at all. You don't know which weak spot to fix first, and there's no one watching your work closely enough to tell you.
A private MCAT coach can give you that read — for $2,000 and up. Most pre-meds can't spend that.
PreMedulla puts the same diagnostic, pattern-tracking, and direction layer at a price a self-studier can actually pay.
Accessibility in medicine starts before med school.
PreMedulla doesn't teach the MCAT. It does the part nothing else does.
There are good free tools, good content libraries, and expensive tutors. Here's where each one leaves a gap, and where PreMedulla fits.
vs. ChatGPT
ChatGPT will answer any question you ask it. It won't grade your reasoning against a real error taxonomy, it won't track your patterns across sections, and it forgets you between sessions. PreMedulla is built around the one thing a general chatbot can't do — a persistent profile of your misses that gets sharper every passage.
vs. a $2,000 tutor
A tutor can diagnose your patterns — premium MCAT tutors typically charge $100–$300 an hour, when they're free, in batches you have to schedule around. PreMedulla runs the same kind of diagnosis on every practice you do, on your own clock, at a sub-$90/month price.
vs. more practice passages
Doing more passages without feedback on your reasoning just logs more reps of the same mistake. PreMedulla is the layer on top: it tells you why a rep went wrong so the next one can go right.
Where PreMedulla sends you for content
PreMedulla doesn't reteach biology, organic chemistry, or the rest. When your profile shows a real content hole, it points you to the resources that already do it well — Sketchy, Khan Academy, AnKing, AK Lectures. The job here is the reasoning and pattern layer they don't touch.
Start with a free diagnosis.
Before you pay for anything, find out what's actually wrong. The free CARS Diagnostic walks you through a guided debrief of your reasoning and hands you a one-page error-pattern report: the patterns you fall for most, the question types where you lose points, and the single weak spot worth fixing first.
No subscription. No card. You'll know more about your weak spots in twenty minutes than a score report has told you all year.
First cohort, early access. Enter your email and you'll get your invite when the Diagnostic opens.

What it'll cost.
The Diagnostic is free and stays free. Paid practice starts at $29/month and caps at $89/month — a fraction of what a private coach charges. Nothing's for sale on this page yet.

Honest answers.
Is this just another AI tutor?
No. A general AI tutor answers questions you ask it. PreMedulla makes you commit to an answer and explain your reasoning first, grades that reasoning against a real error taxonomy, and remembers your patterns over time. The persistent profile of your misses — across sections — is the thing a general chatbot structurally can't do.
I'm not just CARS-stuck. Does this work across the whole exam?
Yes. V1 covers CARS and Psych/Soc fully today; Bio/Biochem and Chem/Physics come next. The brand and the platform are general MCAT — pattern-tracking, diagnosis, and planning work the same way across every section that ships.
Do you use real AAMC passages?
No. AAMC, UWorld, and the rest own their content, and copying it would be wrong and illegal. PreMedulla's passages are original — written and adapted from public-domain sources like Mill, Locke, Hume, and Du Bois — built to the same reasoning demands as the real test.
When does it launch?
The first cohort opens soon, and the early-access list gets invited first. Join the list and you'll know the moment it goes live.
What does it cost?
The CARS Diagnostic is free and stays free. Paid practice starts at $29 a month; see Pricing for the full breakdown. Nothing charges until you choose to subscribe — and nothing's for sale on this page yet.
Who's behind it?
I'm Sean — a recent Yale grad who just took the MCAT and got tired of feedback that stopped at "right" or "wrong." The prep process is overwhelming in time and money, and personalized guidance is gatekept by price. PreMedulla is the tool I wanted while I was studying, at a price a self-studier can actually pay. It's a single-person project right now.
