The big idea
Apps that teach you Spanish, French, or Japanese use AI to figure out what's hard for you. They keep practicing those parts more so your brain really learns.
Some examples
If you keep missing 'el' versus 'la', AI gives you more practice.
AI picks easier words when you're tired and harder when you're on a roll.
Some apps use AI to listen to your pronunciation.
AI can give you a personal practice plan.
Try it!
Try a language app for 5 minutes. Notice if it repeats words you got wrong. That's AI helping you!
