How does Kusari help users stick to their English learning goals?
Kusari uses a commitment device based on behavioral economics. Users 'lock in' a financial stake, and if they miss their daily tasks, a portion of that stake is charged. This financial consequence, inspired by Yale's StickK research, significantly increases goal achievement rates compared to willpower alone.

Kusari offers a tiered pricing model. The base price is $5000 (approximately $33 USD) per month, but users can earn discounts based on their daily achievement. Achieving all daily tasks for 24-30 days results in a $0 charge for the following month, with other tiers offering discounts down to $1000.
