How it works

To check your text, copy and paste or write directly into the online editor above.

Click the Free Check button to check grammar, spelling, and punctuation. If you see an underlined word or text passage, click on the highlighted area for correction options and apply them as needed.

To make sure your sentences are clear and your word choice is perfect, double-check your text.

Click the Deep Check button to detect even difficult-to-spot writing mistakes, such as wrong words, advanced punctuation and capitalization errors, run-on sentences, dangling modifiers, style issues, incorrect tense, and up to ten times more errors than any other grammar checker. To enable advanced corrections and suggestions in the online editor, wait for the check to complete, install the app or browser extension, and reload this page.
