# Proofreader AI Grammar Checker vs AI Email Writer

The clearest difference is monetization model: Proofreader AI Grammar Checker at freemium against AI Email Writer's subscription. Proofreader AI Grammar Checker also leads on ratings volume (3.3K vs 10). AI Email Writer's advantage is review sentiment (100% vs 65%). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Proofreader AI Grammar Checker sells 8 in-app purchases, starting at $4.99 per month and AI Email Writer sells 5 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Proofreader AI Grammar Checker against 4.6 for AI Email Writer. That said, the two scores are not equally well evidenced: Proofreader AI Grammar Checker has 3.3K ratings behind it against 10, so its average is the more settled of the two. Written reviews are what separate them: 65% of Proofreader AI Grammar Checker's written reviews are positive against 100% of AI Email Writer's.

Proofreader AI Grammar Checker ships an update every 3 weeks, AI Email Writer every 2 weeks. Both last shipped on October 30, 2026.
