Our verdict
Excellent for polishing English everywhere you type; AI rewriting is good but paid tiers add up.
How this score works: the DevMixa score is research-based — we compare official pricing, features, documentation, support options, security and data policies, and public user feedback against other tools in the same category. It is not a hands-on test; tools we test ourselves are marked “Tested”.
What is Grammarly?
Grammarly is one of the most widely used writing assistants. It sits inside the places you already write, including Gmail, Google Docs, LinkedIn, Slack and Microsoft Word, and underlines spelling, grammar and punctuation problems as you type. Paid plans add suggestions for clarity, tone, word choice and full-sentence rewrites, plus generative AI that can draft or rephrase text from a prompt.
Where it helps most
For teams that write client emails and proposals in English as a second language, Grammarly is a quick way to make communication look more polished. The tone detector warns when a message may sound too blunt or too casual, and the clarity suggestions shorten wordy sentences. Business plans add a shared style guide and brand tones so everyone writes consistently.
Plans
The free version covers core spelling and grammar corrections and a limited number of AI prompts. Pro unlocks full rewrites, tone adjustments, plagiarism detection and many more AI prompts. Enterprise adds admin controls, security features and analytics. In 2025 the company behind Grammarly rebranded as Superhuman, bringing several productivity products under one name, while the Grammarly product continues.
Drawbacks
Some suggestions flatten your personal voice, and the browser extension can occasionally slow very long documents. Non-English support is limited compared with English. Frequent upgrade prompts on the free plan can be distracting.
Bottom line
If most of your writing is in English and spread across many apps, Grammarly is one of the easiest tools to adopt. Start with the free extension and upgrade only if you need rewriting, tone controls or plagiarism checks.
