Hi, I'm Yuki.
I study how people decide and learn in complex systems.
That means looking at attention, motivation, and behavior. Not what people say they do.
Behavioral data, biometrics, and mixed methods let me measure all three. The findings become product decisions.

Subscriptions I Forgot I Had
I have more than 20 subscriptions. In the last six months I've been on the phone with platforms and credit card companies five times over charges I didn't want. It's July.
The apps that cancel for you break the moment a site changes its flow. This one doesn't click for you. It finds what you're paying for, pulls the current cancellation path, and drafts the email when an email is what it takes.
The model runs on your machine. Your mail is read locally and never uploaded.
Now: testing how accurately a local model can identify subscriptions from receipts.
