Grammarly

Grammarly’s AI checks grammar, spelling, punctuation, tone, clarity, and engagement in real-time across every app and browser you use. The AI features go far beyond spell-check: full sentence rewrites, tone detection and adjustment, email drafting from bullet points, and a personalised writing style profile built from your past writing. GrammarlyGO (their generative AI feature) drafts entire emails, cover letters, and responses. Works natively as a browser extension, desktop app, and inside Microsoft Word, Google Docs, and most writing platforms.
