About Grammarly

As someone who writes for a living, I’m constantly firing off emails, drafting blog outlines, and posting on social media from my phone. I downloaded Grammarly hoping it would save me from embarrassing typos in client emails, and it’s done that and more. It’s not just a spellchecker; it feels like having a patient editor looking over my shoulder, pointing out when my tone is too harsh or my sentence is confusingly long. I rely on it daily across my laptop and iPhone to make sure my writing is clear before I hit send.

Features & Highlights

The core grammar and spelling checks are what I use most. It caught me writing “defiantly” instead of “definitely” just last week—a classic mistake I always miss. Beyond that, the tone detector is a game-changer. I was drafting a sensitive email to a colleague, and Grammarly flagged a sentence as “impolite,” suggesting a softer alternative that totally changed the vibe for the better. I also appreciate the vocabulary suggestions; it offered “consequently” as an alternative to my overused “so,” which made my report sound sharper. The seamless sync is a standout feature—I can start a document on my desktop and polish the final paragraphs on my phone during my commute, and everything is right where I left it.

User Experience

The mobile app is clean and unintimidating. I typically paste text directly into the Grammarly editor or use the keyboard across other apps. There was a specific moment last month when I was trying to craft a concise Twitter thread. The app kept flagging my sentences as “wordy,” and after following a few of its suggestions to trim the fat, I ended up with a much punchier thread that actually got more engagement. The interface doesn’t get in the way; corrections and suggestions appear as simple underlines, and tapping them gives me a clear explanation of *why* something should be changed, which helps me learn. It feels less like an automated tool and more like a helpful guide.

Pricing

The app is free to download and use for the essentials: spelling, basic grammar, punctuation, and tone detection. This covers about 90% of my daily needs. The Premium subscription unlocks advanced checks for clarity, engagement, plagiarism detection, and full-sentence rewrites. I tried the free trial and found the clarity suggestions incredibly useful for longer-form writing, but for my daily emails and social posts, the free version is perfectly adequate and still offers tremendous value. Whether Premium is worth it really depends on if you’re a student writing papers or a professional producing lots of client-facing content.

Updates & Support

I get app updates every few weeks, usually with minor bug fixes or subtle interface tweaks. The bigger feature announcements, like new integration capabilities, come a few times a year. The one time I had a sync issue between devices, I used the in-app support chat. I got a real person who responded within a few hours, asked for some details, and provided a clear fix that worked. It wasn’t instant, but it was effective and polite, which is all I can really ask for.

Security & Privacy

I downloaded Grammarly directly from the official Apple App Store. Privacy is a valid concern with any app that analyzes your text. Grammarly is transparent about its data practices in its privacy policy, stating it processes your text to provide the service but has measures to protect it. For my use—mostly non-sensitive professional and social writing—I’m comfortable with the trade-off. I don’t use it for highly confidential documents like legal contracts or passwords. The free version shows occasional, non-intrusive prompts to upgrade, but I haven’t encountered any disruptive video ads or pop-ups.
