What is this tool?
Grammarly is a writing assistant that flags grammar, spelling, clarity, and tone issues and suggests fixes while you write. It is aimed at professionals, students, and teams who want their everyday writing — emails, documents, messages — to read clearly and on-brand. It works inside the apps you already use rather than as a separate editor. It guides writing rather than producing finished copy on its own.

It reads your text as you write and surfaces suggestions — corrections for grammar and spelling, rephrasing for clarity and concision, and adjustments for tone and brand style — that you accept or ignore inline. It runs where the writing happens: email, documents, Slack, support tools, and the browser, rather than asking you to draft somewhere else first.
The users span individuals polishing their own writing and organizations that want consistent, on-brand communication across a team, with brand-tone and style controls for the latter. It sits on top of your existing tools as a layer over the writing surface.
The boundary to note: it improves and guides text rather than generating finished pieces, and tone suggestions are guidance — the writer's judgement still decides what ships.

Key features
What you can actually do with this tool.
Grammar and spelling
Flags and corrects grammatical and spelling mistakes inline as you write, across the email, document, and chat apps where the writing actually happens.
Clarity rewrites
Suggests more concise, clearer phrasing for clunky or wordy sentences, tightening the message without changing the meaning you intended.
Tone and style
Reads the tone of your writing and suggests adjustments to hit the register you want, helping you sound right while keeping your own voice.
Brand style controls
Lets an organisation set a style guide so a whole team's writing follows the same tone and conventions, keeping communication consistent.
Plagiarism check
Checks whether passages match outside sources, which supports academic and editorial work where originality has to be verified.

Frequently asked
Common questions about this tool, answered.
Does it write content or just edit?
It centres on improving and guiding writing you produce rather than generating finished pieces from scratch, so teams wanting drafts created will pair it with a generation tool.
How does a team keep one voice?
An organisation can set a brand style guide that the assistant applies, so writing stays on the same tone and conventions even across many different writers.
How should I treat tone suggestions?
Tone and clarity prompts are guidance, not rules; they help you see writing through a reader's eyes, but the final wording and judgement stay with you.
Where does it actually run?
It layers onto the apps you already use, so suggestions appear in email, documents, chat tools, and the browser rather than only inside a dedicated window.
How it compares
Context for choosing between this tool and alternatives.
The call is whether you want writing guidance across everything you type or generation of new content. Grammarly suits clarity, correctness, and tone across apps. If your need is producing long-form drafts, a copywriting or content tool covers that; for grammar in a single niche, lighter checkers exist. Decide by whether you want a writing layer over your daily tools or a generator for new pieces.
