Your AI Grammar Tutor: Write Better English, Learn From Every Mistake
NotchTutor is an AI grammar tutor and English writing assistant that goes beyond quick fixes. It corrects your grammar, explains why something is wrong, and tracks your recurring mistakes — turning everyday writing into real progress.
Built for everyday professional writing: emails, Slack messages, docs, and LinkedIn posts.
The grammar checker for professionals who write in English every day — and want it to sound effortless.
If you write business English at work, you've felt this.
- • You rewrite the same sentence three times… and still aren't sure.
- • You avoid "risky" wording, so your message sounds flat or too harsh.
- • You repeat the same grammar mistakes because nobody explains them.
- • You want to improve, but you don't have time for lessons.
NotchTutor is grammar correction that teaches. It corrects, explains, and remembers what you struggle with — so you learn from your grammar mistakes instead of repeating them.
