We're 19lab, a one-person studio in Tokyo. We build small tools for everyday life — from planning through implementation to the care that continues after launch — all by the same hand.
What we've made
Rather than chase trends, we take our time with each product. These are the three we're still refining today.
Matomerun
The ability to read stays with you for life.
Read an article, then summarize it in 40, 80, or 120 characters. An AI trained on real cram-school grading standards scores your work and marks it up like a teacher — a summarization trainer for elementary schoolers and up, in Japanese.

About 19lab
19lab is a small studio in Tokyo making mobile apps and web services that quietly support everyday life.
Rather than chase trends, we take our time with each product — carefully building things made to last.
From planning through implementation to the care that continues after launch, it's the same hands throughout. We take on client work the same way we build our own products.
