Grammarly

What is Grammarly?

Grammarly is an AI writing assistant that checks grammar, spelling, style, and tone in real time and improves phrasing — integrated into browsers, desktop apps, and Microsoft Office. Rather than relying on a separate editor, Grammarly works right where you write: in emails, documents, social media posts, and chats. The free tier covers basic corrections such as spelling and simple grammar; the paid tiers unlock AI rewriting, tone adjustment, plagiarism checking, and full generative features. Worth knowing: Grammarly is built primarily for English — its usefulness for German-language text is limited. If you're weighing the options, see QuillBot vs. Grammarly and DeepL vs. Grammarly.

Grammarly: Strengths and weaknesses

Grammarly's biggest strength is its seamless integration: through the browser extension and apps, it corrects text in real time across almost any web interface and Office program. Its suggestions go beyond pure grammar to cover clarity, word repetition, tone, and readability — for English-language text, detection quality is very good. The AI features also let you rewrite entire paragraphs, shorten them, or adjust their tone.

Weaknesses show up mainly outside English: for German, Grammarly does not provide a full check, so German-speaking users tend to reach for alternatives. The tool also occasionally flags stylistically correct phrasing, which can be distracting in creative or technical writing. Grammarly does not offer a public API for developers.

Pricing and plans

Grammarly offers a generous free tier covering spelling, basic grammar, and some tone suggestions. Paid plans start at around $12 per month (billed annually; monthly billing costs more) and unlock advanced style and clarity suggestions, AI rewriting, tone adjustment, and a plagiarism checker. There are also Team and Business plans with centralized style management and per-user billing. Exact terms can vary by region and promotion — it's worth checking the Grammarly tool page and the official website before subscribing.

Who is Grammarly for?

Grammarly is especially well-suited to anyone who writes regularly in English — students, professionals on international teams, content creators, and non-native speakers who want to phrase things more confidently. The free tier is enough for occasional corrections, while the Pro features pay off mainly for heavy writers. For predominantly German-language text, however, Grammarly is the wrong choice; here DeepL (translation and rephrasing) or QuillBot (paraphrasing with German support) are the better fit.
