What Grammarly does
Grammarly checks, rewrites, generates, and standardizes writing across browsers, desktop apps, documents, and mobile devices.
Grammarly’s practical advantage is distribution. Suggestions appear where people already write instead of forcing every email, document, and form into a separate chatbot. It covers correction and tone as well as drafting, rewriting, plagiarism checks, and AI-text detection on eligible plans.
The strongest workflow is selective rather than automatic. Writers should review explanations, accept only changes that preserve meaning, and run a separate factual check. Organizations handling confidential or regulated data should configure privacy, application controls, retention expectations, and contracts before deployment.
How Grammarly works
Grammarly analyzes text in supported writing surfaces and offers corrections, rewrites, tone adjustments, and generative assistance. Team plans can apply shared terminology, brand tone, snippets, and governance controls.
Work in a supported writing app
Grammarly runs through its editor, browser extensions, desktop apps, Office integrations, or mobile keyboards. It analyzes the text and, where enabled, surrounding context needed to understand the message.
Detect communication issues
The system evaluates spelling, grammar, clarity, fluency, tone, and configured team rules. Generative features can also interpret an instruction to compose, shorten, rewrite, or adjust a passage.
Propose a change—not a command
Corrections and rewrites appear inline with explanations or alternatives. Team style guides, brand tone, snippets, and approved terminology can make those suggestions more consistent across writers.
Accept selectively
The writer decides whether each change preserves intent, specialist meaning, and personal voice. Facts, citations, promises, and AI-detection results require separate human review; grammatical confidence is not factual verification.
