Clear credits for every group.

Nihongo Buddy is free to add and try. Your group only needs payment details if it runs out of included credits and chooses to buy more.

One-time credit pack

$5

5,000 credits = up to 5,000 Nihongo Buddy replies

Each translated message or conversation reply uses one credit. Credits are applied to the LINE group that completes checkout.

Included

5,000 starting credits

Every new group starts with 5,000 credits, with no card required and no commitment. Add the bot and start using it right away.

Typical usage

50-100 credits per week

Many groups use about 50-100 credits per week, so 5,000 credits can last a long time for casual group chat translation.

Bonus

2,500 feedback credits

Groups can answer one product feedback question in the menu to receive an additional 2,500 free credits.

Payments are processed securely by Stripe only when a group chooses to buy more credits. Credits are not a subscription and are not automatically renewed.

Privacy-forward

Translation mode does not store message history.

Memory is optional and encrypted. When it is off, Nihongo Buddy replies without storing previous messages for future context.
