Make your Korean sound more natural, one short draft at a time.
Nati reads your learner draft like a tutor would: it keeps your meaning, rewrites the Korean more naturally, and explains the change in clear English.
More like a careful tutor than a generic checker
The goal is not only to mark errors. The goal is to respond the way a helpful Korean tutor would respond to a short learner post. Nati is inspired by learner writing spaces like r/WriteStreakKorean, where people practice Korean through short drafts and feedback.
Many learner sentences are understandable but still feel stiff, repetitive, or slightly off. Nati targets that layer.
Instead of silently replacing the whole sentence, the app breaks the rewrite into visible changes you can inspect.
The explanation is part of the product, because learning is the point, not just getting a cleaner sentence.
What Nati notices in a learner draft
The useful part is not only the rewritten Korean. It is knowing what sounded off, why the change helps, and what pattern to reuse.
-
Naturalness
Understandable Korean that still sounds translated
Nati looks for phrasing that a Korean speaker would probably reword, even when the grammar is technically acceptable.
-
Tone
Politeness and speech-level mismatches
The feedback calls out when wording feels too casual, too stiff, or slightly mismatched for the situation.
-
Reusable lesson
A short explanation you can apply next time
Notes are written for learners, so the feedback turns into a study point instead of a one-time revised sentence.
Use Nati when a sentence is close, but not quite natural
These are the moments learners often search for help: the sentence is mostly understandable, but you want a tutor to show what a more natural Korean version would sound like.
-
Korean diary or journal entries
Turn a short daily entry into smoother Korean while keeping your original meaning and level.
-
Homework answers and self-introductions
Check whether the sentence sounds like something a learner could naturally say, not just whether it has obvious mistakes.
-
"Does this sound natural?" questions
Get help with translated-sounding phrasing, repetitive endings, awkward word choice, and tone that feels slightly off.
Frequently asked questions
What kind of Korean writing works best in Nati?
Nati is strongest on short learner drafts such as diary entries, homework responses, self-introductions, and questions about whether a sentence sounds natural.
Can Nati help with Korean that is understandable but unnatural?
Yes. That is one of the main use cases. Nati looks for Korean that is understandable but still feels translated, stiff, repetitive, or slightly mismatched in tone.
Do I get explanations or only revised Korean?
You get both. Nati is built around explanation-first feedback, so you can see what changed and why each rewrite is stronger.
