Grammarly

2:02 Grammarly is an AI writing assistant that checks spelling, grammar and tone as you type in most apps and websites, rewrites sentences, and offers AI agents such as a Proofreader, a Paraphraser, Reader Reactions and an AI Grader. As of Nov 6, 2026 it is free with 100 AI prompts a month; Pro costs $12 a month with 2,000 prompts a member and adds full-sentence rewrites, tone changes and plagiarism and AI-text detection. On Oct 29, 2025 the company behind Grammarly renamed itself Superhuman; Grammarly keeps its name as one product in the Superhuman suite, beside Coda, Superhuman Mail and the new Superhuman Go assistant.

Grammarly is the pick for polishing writing wherever you already type, especially email, documents and school work, without pasting into a chatbot. For drafting long pieces from scratch or reasoning through a topic, a general assistant such as ChatGPT, Claude or Gemini does more; inside Word and Outlook at work, Microsoft 365 Copilot covers similar ground.
