The Best Grammar Checker for Mac: A 2026 Guide
Find the best grammar checker for Mac. This guide explains how to choose a tool based on accuracy, privacy, local AI, and system integration for your workflow.
Looking for a Typoly alternative? Both apps fix your writing in any macOS text field. This comparison breaks down Typoly and RewriteBar to help you decide which tool best fits your workflow.
Typoly is a cloud-only macOS menu bar app focused on one job: correcting spelling, grammar, and punctuation in place with a single key. It offers a Proofread mode and a Contextual mode, runs on its own fine-tuned model, and sells prepaid credit packs. RewriteBar also fixes grammar with one shortcut, directly in the text field, and adds tone changes, summaries, translation into 500+ languages, and your own custom commands. You choose the AI model, including local models that run on your Mac. RewriteBar starts at $29 for a one-time license. An optional RewriteBar Gateway add-on ($5/month or $40/year) adds hosted models if you do not want to use your own API key.

One-Time License: Includes all RewriteBar features but requires you to set up your own API accounts with AI providers (OpenAI, Anthropic, etc.). You pay the providers directly for usage.
Subscription: Includes all features from the one-time license plus RewriteBar Gateway access and priority support. No need to set up API accounts—you can access the same AI models through our cloud service. You can still use your own API key (BYOK) or local models at any time.
