  Grammarly

  AI writing assistant for grammar, tone, clarity, and generative drafting.

  Grammarly checks grammar, spelling, clarity, and tone across the apps you already write in, and layers generative AI on top for drafting, rewriting, and tone adjustment. It works as a browser extension, desktop app, mobile keyboard, and web editor, with detection for plagiarism and AI-generated text on paid tiers.

  AI insight: It runs as a system-wide overlay across native apps and the browser, so the assistant follows you everywhere, not just one editor.
