No Downloads. No Sign Ups. Just a Free and Reliable Spelling and Grammar Checker.

The Perfect Tense spelling and grammar checker is completely free to use. There is no download or sign up required to use Perfect Tense. Unlike other online spelling and grammar checkers, our free version corrects all of the same spelling, grammar, and punctuation mistakes as our full version.

To use Perfect Tense, just paste or type your text into the text area above and any errors will automatically be underlined. Perfect Tense underlines suggestions in yellow and corrections in red. Once you hover over the underlined word, Perfect Tense will show the recommended replacement, which you can choose to accept or ignore.

In addition to spelling, grammar, and punctuation correction, this free checker also displays the number of characters, the number of words, and a grammar score that assesses the overall quality of the text you entered. The score is based on the frequency and severity of errors and updates as you accept and reject Perfect Tense replacements.
