Verdict

The call

The clearest difference is ads: AI Grammar Checker at none against Proofreader's shown. AI Grammar Checker also leads on rating (4.5 vs 4.3) and update cadence (every 2 months vs every 3 months). Proofreader's advantage is device support (3 vs 1). On price, ratings volume, in-app purchases and monetization model there is nothing between them.
