Grammarly

Overview

Grammarly is an AI writing assistant that checks grammar, spelling, clarity, tone and style as you type, then layers generative AI drafting and rewriting on top. It works across the browser, desktop apps, Microsoft Word and Google Docs through extensions rather than in a single editor, so the same suggestions follow you into email, documents and chat. Alongside the core assistant it offers AI agents such as a plagiarism and AI-text detector, a citation finder and a tone rewriter, and its Enterprise plan adds shared style guides, brand tones and team analytics. Grammarly reports use by around 40 million people and 50,000 organizations.

Best for individuals and teams who want grammar, clarity and tone help across every app they write in.

Grammarly's strength is reach: it follows you into almost every app you write in and fixes grammar, clarity and tone in place, which is why the free tier alone is useful for everyday writing. Its generative AI drafting is capped by a monthly prompt allowance, and it is less of a long-form marketing content engine than tools like Jasper. For individuals and teams who want consistent, on-brand writing across email, documents and browsers, it is the default choice.
