🧬  now accepting multi-gigabyte Pranovo scans

Some brains
are bigger.
Prove yours.

Upload your raw MRI. We extract your brain, measure every wrinkle, weigh it down to the gram, and mint you an officially notarized wrinkly score. Then we stick you on the leaderboard so the world can see.

Drop your MRI. (yes, the whole thing.)

DICOM, NIfTI, or that 14GB directory your radiologist emailed you. We handle it.

how the sausage brain is made

From raw scan to ranked wrinkles in ~4 minutes.

01
ingest the slab

Your multi-GB scan gets streamed straight into the pipeline. No downsampling, no cheating.

02
skull-strip & segment

We peel the skull, isolate the cortex, and mesh every gyrus and sulcus at sub-mm resolution.

03
measure mass & wrinkliness

Estimated grams. Gyrification Index. Cortical folding density. All the numbers that matter.

04
get your STL + your rank

A 3D-printable STL lands in your inbox. Your wrinkly score hits the leaderboard. Talk ensues.

People are uploading. People are coping.

"I paid $3,200 for a brain MRI. OfficiallyBigBrained told me my wrinkly score is 412. I am in therapy."

— @smoothbrain_andy

"Beat my brother by 14 points. Christmas is ruined. Worth it."

— dr. megan, phd (neurology)

"3D printed my brain. My dog keeps licking it. Eleven out of ten."

FAQ

Is this, like, medical?

No. It is vibes. And geometry. We do not diagnose anything. If something on your scan looks concerning, please talk to a doctor — a real one, not us.

What counts as "wrinkly"?

We blend gyrification index, cortical thickness, and surface folding complexity into a single 0–1000 score. More wrinkles + more surface area = higher score. It is peer reviewed by us.

Do I need a fancy scan?

T1-weighted structural MRIs work best. The Pranovo multi-gigabyte ones are our favorite. iPhone photos of your head, regrettably, will not work.

Is my brain data safe?

Scans are processed then deleted by default. You can opt in to keeping your anonymized mesh for leaderboard integrity. See the privacy page (soon).

Can I hide from the leaderboard?

Yes. Private mode exists. Cowards will be respected.

How much?

One free scan per person. Additional scans and premium STL finishes via Stripe (coming soon).
