Which checker should I use?

If you are not sure, start with the grammar checker. It runs the full check: spelling, grammar, punctuation and style, all at once. The other tools use the same engine but are tuned for a specific job.

• Spell Checker only flags misspelled words, which is useful when you want a fast pass without style suggestions.
• Punctuation Checker focuses your attention on commas, apostrophes, capital letters and spacing.
• Sentence Checker is best for a single line, such as a subject line, caption or text message.
• Essay Checker and Paragraph Checker are built for longer writing, with readability scoring and reading time.
• UK English and Spanish checkers apply the right dictionary and rules for that language.

Learn the rules, not just the fixes
