Your second brain, heard at last

Trust your gut.
Then date it.

Your gut is your second brain. Stoolmate reads your stool and matches you with people whose insides run like yours.

All stools are of real poopers and used for compatibility purposes only.

The mission

Your second brain has been single long enough.

Your gut carries five hundred million neurons — enough to run a small mammal. Science calls it the second brain. It decides when you're hungry, when you're nervous, when something feels off about the person across the table. And every morning, it publishes its findings.

Modern dating reads your photos, your job title, your taste in music. Nobody reads the findings. Stoolmate does — because two people whose insides agree have a head start no personality quiz can fake.

Give the stomach a say.

How it works

Three steps between you and your stoolmate.

Upload

Photograph your stool. Add your face and a short bio — what you eat, how often you go, how it comes out.

Analyze

Stool Analysis reads consistency, color, form, length, and frequency, anchored to the Bristol Stool Scale.

Match

Meet poopers whose insides run like yours. Your Match Score shows exactly how alike your stools are — and unlocks messaging.

What we analyze

Six measured dimensions. One honest signal.

Consistency

Bristol Stool Scale, Types 1–7. The clinical gold standard, applied to romance.

Color

Brown, green, yellow — and the ones you should see a doctor about.

Form & length

Measured to the centimeter.

Frequency

Movements per day. Your personal rhythm.

Diet signals

What you eat, read back through what you leave behind.

Odor

The final, most honest dimension.

Frequently asked questions

Is Stoolmate serious?

Completely. Your gut carries five hundred million neurons and has no representation in modern dating. We're fixing that.

What happens to my stool photos?

They're read by Stool Analysis across six measured dimensions, then used to compute your Match Scores. They're never shown to other poopers without your say-so.

What if I'm irregular?

Irregular is a rhythm too. Frequency is one dimension of six — somewhere out there is a pooper on your schedule.
