Lingle

Lingle is an AI-powered language tutoring platform that offers real-time voice lessons with a virtual tutor. The tutor plans each session, leads activities, corrects mistakes in the moment, and adapts difficulty based on learner performance. It supports eight languages including Japanese, Spanish, French, and Korean. Lessons follow a structured sequence of warm-up, focused practice, roleplay, and recap, rather than random chat. A shared whiteboard displays corrections, new vocabulary, and grammar explanations as they occur. Users can request a mini-course on any topic, which Lingle generates with explanations and examples. Lingle maintains a persistent memory of each user's goals, mistakes, and personal interests. It uses this memory to bring back relevant points in later sessions and to chart progress toward fluency milestones (e.g., B1 to B2). Vocabulary used in lessons is automatically converted into spaced-repetition flashcards, reinforcing retention.

Traditional tutoring requires scheduling and can be expensive; self-study apps often lack real conversation.
