# AI Grammar Check vs ReplyWise

The clearest difference is review sentiment: ReplyWise at 100% against AI Grammar Check's 50%. ReplyWise also leads on rating (5.0 vs 4.4) and update cadence (every 3 weeks vs every 6 weeks). AI Grammar Check's advantage is monetization model (freemium vs subscription) and ratings volume (30 vs 1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. AI Grammar Check sells 3 in-app purchases, starting at $7.99 per 7 days and ReplyWise sells 1 in-app purchase, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
