Jolii AI

On Android and iOS, Jolii AI turns Netflix and YouTube viewing into language practice. Jolii AI is an AI language learning app that teaches vocabulary and grammar from the shows and videos you already watch, then lets you practice speaking with a built-in chatbot.

It gives pronunciation feedback as you talk, and lessons adapt to your level and learning style.

Beginners are covered, as are more advanced learners.

Learning from context is the main idea.

Words and grammar come attached to real scenes, which helps them stick better than a flashcard list.

Game-style features and interactive tools break up the study sessions, and you can work on several languages at once.

Jolii is a dedicated app, not a browser extension, so you need to download it.

Watching Netflix content inside the app requires an active Netflix account.

The service needs its own subscription, though a free trial is available.

It is pitched as a cheaper alternative to a private tutor.
