Line-by-Line Grammar Corrections
Every sentence you write is analyzed to provide specific, actionable feedback. Corrections are categorized into Grammar, Style, and Spelling, so you understand not just what was wrong, but why.

This detailed breakdown turns every mistake into a clear learning opportunity, helping you internalize the rules of your new language.
Personalized AI Coaching Note
After each entry, you receive a unique note of feedback and encouragement written entirely in your target language.
