Overview

About Grammarly

Grammarly underlines spelling, grammar and tone problems as text is typed, working through a browser extension, desktop apps and phone keyboards rather than its own editor. The free tier covers corrections plus 100 AI prompts a month; Pro raises that to 2,000 and adds rewriting, plagiarism checking and AI-text detection. Since October 2025 the product has been one of three under Superhuman, the renamed parent that also owns Coda and Superhuman Mail.

Editorial verdict

Pros & cons of Grammarly

high confidence

Still the default for catching mistakes inside other people's software, but the free tier has quietly become an AI-prompt meter and the honest price is $30 unless you commit to a full year.
