Description
LangDiary is a thoughtful journaling app that helps you improve your writing skills in a new language through daily practice and AI-assisted feedback. Instead of writing in your native language, you express your thoughts in the language you are learning and increase both your fluency and confidence.
After submitting your submission, LangDiary provides AI-driven corrections that highlight errors and offer clear suggestions for improvement. There are no real-time prompts or auto-corrections, so you can write freely and naturally without interruption. Once checked, you can compare your original input with the corrected version to see how your writing develops over time.
LangDiary supports German, Dutch, Italian, French, Spanish and English. Your entries are securely stored on your device and privately synced to iCloud - only you can read them. If you choose to receive corrections, your submission is shared anonymously and only for correction.
LangDiary creates a safe, private space where you can improve your language skills - one journal entry at a time.
Start writing in your target language and take your writing skills to the next level.
