AI PoweredYour sentence
학교를 가요.
Improved sentence
학교에 가요.
Why this is better
In Korean, movement to a place uses the location particle '에', so '학교에 가요' is correct. The object particle '를' is not used with '가다' in this meaning. Also, '가요' is the natural polite present tense ending.
Alternatives
- - 학교에 갑니다.
- - 학교 가요.

Our Vision
We are building a language coach that grows with you, not just a sentence fixer.
LinguaCraft started with one goal: make high-quality language feedback feel warm, practical, and immediate. We want to turn corrections into momentum, so every mistake becomes vocabulary, review material, and a clearer next step.
Vocabulary Saving and Smart Drilling
Save words straight from your corrections, group them by theme, and review them with spaced repetition drills that stay tied to real sentences you wrote.
Voice Input
Speak instead of typing and get instant feedback on pronunciation-driven mistakes, phrasing choices, and spoken-style sentence structure.
Grammar Lessons After Mistakes
When you repeat a pattern like particles, tense, or word order, LinguaCraft will offer a short focused lesson right after the correction.
YouTube and Netflix Subtitle Extension
Turn shows and videos into live study material with subtitle lookup, one-click saving, and instant sentence explanation while you watch.
Our Blog
A home for study methods, language notes, learner stories, and practical articles on sounding more natural in Korean, Japanese, and Chinese.
Workbooks and Wordbooks
Printable and digital study packs built from the same mistakes learners make most, so practice feels structured instead of random.
