What does the AI Grammar Checker fix?

It fixes grammar errors (subject-verb agreement, tense consistency), spelling mistakes, punctuation issues, and in Improve mode, also suggests clarity and style improvements. Each change is explained with a brief reason.

What's the difference between 'Fix Errors' and 'Improve' mode?

Fix Errors mode only corrects clear grammar, spelling, and punctuation mistakes — it never rephrases or restructures your text, preserving your voice. Improve mode goes further and suggests clarity and style improvements to make your writing more readable.

What is the track-changes diff view?

The diff view shows exactly what changed — deleted text appears in red with strikethrough, and added text appears in green. This is the same as 'Track Changes' in Word, so you can instantly see every modification.

What's the character limit?

Up to 10,000 characters per check — roughly 1,500-2,000 words. For longer documents, split them into sections.

Will it change my writing style?

In Fix Errors mode, no — it only corrects objective errors. In Improve mode, it may suggest rephrasing for clarity, but the goal is always to keep your core message and voice intact.
