RewriteMate vs Grammarly

Two AI writing assistants, two very different approaches. Here is how they compare for macOS and iOS users who want to rewrite text anywhere.

Key Differences

Grammarly is primarily a grammar and spell-checking tool that added AI rewriting features. RewriteMate is built from the ground up as a rewriting tool — it focuses on helping you rephrase, improve tone, and restructure text quickly across any app on macOS and iOS.

The biggest difference? RewriteMate works system-wide on macOS as a menu bar app, while Grammarly is limited to its own editor on desktop. On iOS, both offer keyboard extensions, but RewriteMate gives you full control with custom rewrite instructions.

Pricing

RewriteMate starts at $5.99/month for the Pro plan, with a free tier available. Grammarly Premium costs $12.00/month. For users who primarily need AI-powered rewriting rather than grammar checking, RewriteMate offers better value.

RewriteMate also offers a BYOK (Bring Your Own Key) plan for $29.99 one-time on macOS, ideal for users who already have API access to their preferred AI provider.

The Verdict

If you need a grammar checker with occasional AI rewriting, Grammarly is a solid choice. But if your goal is to rewrite, rephrase, and improve text across every app on your Mac or iPhone — with full control over tone and style — RewriteMate is the better tool for the job.
