Read the draft for meaning
The first job is to understand what the learner is trying to say, including context, tone, and the likely intent behind the sentence.
How Nati works
From learner draft to natural Korean feedback.
Nati is built around a simple tutoring loop: understand what you meant, rewrite the Korean so it sounds more natural, then explain the changes that are useful for your next sentence.
The feedback flow
Nati follows a tutor-like order instead of treating the sentence as a pile of isolated grammar mistakes.
Rewrite only where it helps
Nati then produces a smoother Korean version while trying to keep the learner's meaning and level intact.
Explain the useful change
The explanation focuses on the change a learner can reuse, whether the issue is naturalness, grammar, tone, or repetition.
What Nati looks for
The feedback is tuned for the parts of Korean writing that often make learner sentences feel close, but not quite natural.
-
Translated-sounding phrasing
Some sentences are understandable but still sound too close to English structure. Nati looks for that naturalness layer.
-
Grammar that changes meaning
The app pays attention to particles, endings, tense, and other choices that can shift what the sentence actually says.
-
Tone, politeness, and repetition
Korean often depends on the relationship and situation. Nati flags wording that feels too stiff, too casual, or repetitive.
What Nati is not trying to be
Clear limits make the tool more useful. Nati is focused on short learner drafts and explanation-first feedback.
-
Not a full essay grader
It is not designed to score long essays, grade TOPIK writing, or judge every possible rhetorical choice.
-
Not a human tutor replacement
It can help you practice more often, but a human teacher is still better for personal goals, nuance, and follow-up.
-
Not for private or sensitive writing
Use short practice drafts, synthetic examples, or writing you are comfortable sending to an AI service.
Why the flow is shaped this way
Nati is inspired by learner writing feedback patterns from spaces like r/WriteStreakKorean: short drafts, natural rewrites, and notes that help the next attempt. The goal is to make that learning loop easier to start whenever you have one or two Korean sentences to test.
