ABOUT KASANE
For those who take responsibility for their code's quality.
AI lets anyone write code that works. KASANE verifies the code you write with layered grading, building the eye to judge quality.
THE NAME
The origin of the name "Kasane"
The name KASANE comes from "kasane-irome," the layered color combinations of Heian-era court dress.
It's an aesthetic of layering the outer and lining fabrics, and colors for each season, into a single outfit.
KASANE carries that aesthetic of layering into skill assessment. Frontend, backend, database, performance — on full-stack problems, these four layers combine to measure how complete your code is.
