The hardest part of learning a language is getting speaking practice — it requires a patient, available conversation partner who will tolerate mistakes and help you improve. AI provides exactly this: a tireless voice conversation partner available at any time.
WHAT TO LOOK FOR
Native-language conversation
Speak in French, Spanish, German, Italian, Portuguese, Japanese, Chinese, Korean, and more. Lucy understands and responds in the language you use.
Error correction
Ask Lucy to correct grammar and vocabulary errors as you speak. It can correct inline, offer alternatives, or hold corrections until the end of the sentence — your preference.
Vocabulary building
Ask for the word for something, ask to hear it used in a sentence, or ask Lucy to quiz you on vocabulary in a topic area. Voice-based vocabulary learning is faster than flashcard apps.
