Our Method
Grammar Polish is an AI-powered writing mentor that turns everyday English sentences into clear, personalized grammar lessons. Paste anything you've written — an email, a message, a post — and get instant corrections, the rule behind each fix, a naturalness score, and alternative phrasings. Then learn from your mistakes with lessons and quizzes that adapt to your weak spots. Everything you write is private to you, and your progress saves across devices when you log in.
Why your own mistakes teach you best?
The grammar you remember years later almost always came from a mistake you made for real — a sentence that mattered to you, corrected with a clear reason attached. Abstract exercises fade; personal corrections stick. Grammar Polish is built entirely around that insight. Every time you polish a sentence, the feedback does three things at once: it fixes your text, it names the rule behind the slip, and it quietly logs the category so your future lessons can target it.
The six principles
Learn from your own words
Most grammar tools drill you on filler sentences nobody would ever write. Here, the text you analyze is yours — real emails, posts, and messages you actually care about. Memory sticks when the example is personal.
Feedback that names the exact slip
Every correction points to the specific rule behind it and explains why your version falls short. You're not just handed a fix — you're handed the reason, so the same mistake stops recurring.
A weakness map built from your mistakes
Each correction quietly categorizes where you slipped — verb tense, articles, prepositions, and more. Over time you get a clear picture of which areas trip you up most, instead of guessing.
Lessons aimed at your gaps
Because your weaknesses are tracked, lessons and adaptive quizzes can target the exact topics you struggle with. No more relearning what you already know — every minute goes where it counts.
Compare to decide
When two phrasings both feel right, the comparison engine judges them side by side and explains which wins and why. You learn the nuance behind a choice, not just a correct answer.
Badges and momentum
Small daily wins — a topic badge, a rising score — turn grammar into a habit you want to keep. Progress you can see is progress that compounds.
Why it beats generic grammar drills
Traditional grammar apps front-load rules and test you on detached examples. The problem is transfer: acing a fill-in-the-blank exercise rarely changes how you write the next real email. The gap between practice and reality is where progress leaks out.
Grammar Polish flips the order. You write first, then learn. The lesson arrives at the exact moment a mistake is meaningful to you — which is when the brain is most willing to encode it. Your history becomes a personalized curriculum: the categories you slip on most are the categories the lessons and quizzes focus on, automatically.
The result is a feedback loop — write, get corrected, understand the rule, fill the gap, write better next time — that closes itself around your actual habits instead of a generic syllabus.
Start with one sentence
You don't need to study grammar to improve — you just need to learn from the sentences you're already writing. Paste one into the Correct tab and let the feedback do the teaching.
