For grown-ups, a five-minute habit.
For kids, a rescued cat who turned into an English teacher.
Two products. One quiet philosophy.
W78 sits between behavioral science and language education.
Everything we make answers one quiet question:
what brings a learner back tomorrow?
We start with a five-minute promise. The kind small enough to keep is the only kind that compounds. Coming back is what builds the rest.
We build Korean-first content and Korean-tuned pronunciation evaluation in-house. Nothing here is translated from a foreign tool — it's ours from the first line.
Our kids' service runs without ads, follows COPPA, and treats parental trust as our most important asset.
In one household,
grown-ups and kids learn English on different timelines.
Five minutes a day. An English habit built on behavioral science. Streaks, XP, and badges add up to one quiet feeling: today, I showed up. Thirty days at a time, no willpower required.
A rescued stray turns into an English teacher. Kids collect words alongside the cat; parents pick up vocabulary by watching over their shoulder. No ads, COPPA-compliant, one account per family.
Partnerships, press, hiring —
