Where the differences really matter
Explanations: the biggest practical difference
When Grammarly catches an error, you see a suggestion and optionally a short label ("passive voice," "wordiness"). The reasoning is mostly implicit. For experienced writers, that's fine. For anyone building English skills — non-native speakers, early-career professionals, or anyone who keeps repeating the same mistakes — it's not enough.
NotchTutor explains each correction in plain language. Not a grammar textbook label but a sentence that tells you why the original was wrong and why the fix works. Over weeks, those explanations compound into real language intuition — and illuminate why writers repeat the same grammar mistakes even after years of correction.
Privacy: local vs cloud
Grammarly is a cloud service. To analyse your text, it sends it to Grammarly's servers. That's how it delivers fast, accurate, cross-platform corrections — and for most use cases, it's a reasonable trade-off.
NotchTutor processes everything on your Mac with no network requests for the text itself. If you write client proposals, legal documents, confidential strategy memos, or anything you'd prefer to keep off third-party servers, the difference matters.
Platform: breadth vs depth
Grammarly wins on platform breadth. It supports Windows, macOS, iOS, Android, and has browser extensions for Chrome, Safari, Firefox, and Edge. If you split your work across devices and operating systems, Grammarly's reach is hard to match.
NotchTutor is macOS-only — and unapologetically so. Being native to the platform means tighter integration, lower resource use, and features like notch-bar access that browser-based tools can't replicate. If macOS is your primary work environment, you lose nothing and gain a lot.

Is Grammarly free?
Grammarly offers a free tier with basic grammar and spelling correction, and a paid Premium tier that unlocks advanced suggestions for style, tone, and clarity. NotchTutor's core features — grammar correction, explanations, and pattern tracking — are free.
Does NotchTutor work in browsers like Grammarly's extension does?
NotchTutor is a native macOS app that works system-wide, including inside browser text fields, without a separate extension. Grammarly's browser extension is deeply integrated across web apps and is one of its biggest advantages for users who work primarily in browsers.
Which tool is better for privacy?
