What makes an AI language tutor actually useful
"AI language tutor" now describes anything from a chat window bolted onto a course to a system that actually adapts to you. The difference is what happens beyond the conversation.
Four things worth checking for
- Does it know anything about you? A tutor that generates every sentence generically isn't personalized — it's a chatbot with a language-learning skin. Language Ninja threads your profile (name, city, profession, hobbies, goal) into every lesson, story, and conversation.
- Does it schedule review, or just chat? Talking to an AI once doesn't build vocabulary — spaced repetition (FSRS here) does, by resurfacing exactly what you're about to forget.
- Does it score your speaking, or just respond to it? A real speaking exam with strengths/improvements feedback is different from an AI that's just polite about your grammar.
- Does it lead somewhere? A CEFR-aligned path (A1→C2) with milestone tests and certificates gives you a real target, not an endless chat.
