Verdict

The call

The clearest difference is rating: Proofreader AI Grammar Checker at 4.7 against GrammarBot's 1.0. Proofreader AI Grammar Checker also leads on ads (none vs shown) and ratings volume (3.3K vs 2). GrammarBot's advantage is in-app purchases (none vs 11) and update cadence (every 5 days vs fortnightly). On price, review sentiment and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Proofreader AI Grammar Checker holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: Proofreader AI Grammar Checker has 3.3K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 65% of Proofreader AI Grammar Checker's written reviews are positive against 67% of GrammarBot's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Proofreader AI Grammar Checker ships an update fortnightly, GrammarBot every 5 days. The most recent releases landed on October 17, 2026 and October 12, 2026 respectively.
