What is an academic language checker?
An academic language checker goes beyond basic grammar to evaluate whether your writing meets the formal standards of scholarly publication. It detects informal vocabulary, vague phrasing, passive voice overuse, sentence-level clarity issues, and common mistakes made by non-native English writers. Journal editors and reviewers expect precise, formal, and unambiguous language, anything less creates friction in peer review and can contribute to rejection. CheckMyManuscript's language analysis covers grammar, style, clarity, and academic register across your entire manuscript.
Language issues we detect
Grammar and syntax errors
Catch subject-verb disagreement, tense inconsistencies, and sentence fragments.
