Lingo Journal
AI feedback for language study
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Many language learners can understand what they read or hear —but struggle to write or speak naturally in real life.
This app helps you turn everyday thoughts into real language ability through daily journaling in your target language. With AI-assisted feedback, you refine grammar, expression, and usage as you write about your own life — transforming passive knowledge into confident, usable communication.
Key Features
• Multilingual Journaling
Write journals in Chinese, English, Spanish, Japanese, Korean, French, or German, or naturally mix multiple languages in a single entry.
• AI Writing Feedback
Receive grammar corrections and suggestions for more natural, native-level expressions in your target language. Multiple revision styles support different learning goals.
• Context-Aware Translation
Translate ideas based on meaning and context, helping you learn how thoughts are naturally expressed — not word by word.
• Expression Breakdown & Explanation
Entries are broken into meaningful language chunks, with clear explanations of how words and phrases work together in real usage.
• Vocabulary Collection & Flashcards
Save useful words and expressions from your writing and review them anytime with built-in flashcards.
• Flexible Journal Organization
Use tags and categories to organize journals, reflect on progress, and build consistent writing habits.
