Grammarlyzer Grammar Checker
Grammarlyzer checks common English grammar, spelling, punctuation, and usage issues in the browser. It is built for students, workplace writers, support teams, and anyone revising emails, essays, reports, or web copy before sharing it.
The routine grammar checker runs locally in the browser, so ordinary grammar checks do not require an account. AI Polish is separate: it rewrites a draft only when the user presses the Polish button, and that request may require sign-in and quota checks.
How the Free Checker Fits Real Editing
Use the checker as a first pass over a draft, then review the sentence yourself before accepting changes. The most useful workflow is to catch mechanical issues first: repeated words, misspellings, agreement problems, punctuation warnings, and common confused-word patterns.
For decisions that depend on audience, company style, citation rules, legal wording, or the exact meaning of a sentence, use the linked grammar guides as an explanation layer rather than treating any automated suggestion as final.
What the Checker Can and Cannot Do
The checker is useful for common spelling mistakes, agreement problems, punctuation warnings, repeated words, and frequent confused-word patterns. It cannot fully judge legal meaning, citation style, private company rules, audience intent, or every context-dependent grammar choice. Users should review suggestions before accepting them.
Start with the strongest learning hubs when a suggestion needs explanation: punctuation marks, possessives and contractions, exact homophones, business email vocabulary, and time progression words.
Trust and Review Pages
Read the guide for workflow limits, the privacy policy for data handling, the editorial policy for content standards, and the contact page to report a correction or checker issue.
