Managing Your Plan

The Plan page in Settings lets you view your current plan, upgrade to a paid plan, and activate a License Key.

Subscription plans

Plan	Usage limit	Price
Free	21 inputs/day	Free
NKTg AI Plus	55 inputs/day	$2 USD/month (~50,000 VND)
NKTg AI Pro	Unlimited inputs	$5 USD/month (~125,000 VND)

All plans use the same NKTg AI system with full features and the same algorithm. The only difference is the number of inputs allowed per day.
