# AI Grammar Check vs Proofreader

Both are free to download. AI Grammar Check sells 4 in-app purchases, starting at $4.99 per 7 days and Proofreader sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

AI Grammar Check ships an update every 2 months, Proofreader every 3 months. Both last shipped on November 3, 2026.
