At a glance

Grammarly is an AI writing assistant that corrects English grammar, spelling and style in real time almost everywhere you write, including browsers, email, Word and Slack. After its operator renamed the company Superhuman in October 2025, Grammarly is also sold in a bundled plan with Superhuman Go (AI assistant), Docs (formerly Coda) and Mail. It is especially useful for students and office workers who often write English emails/reports/papers. Korean is also a supported language, with spelling/basic grammar correction (red underlines) and inline translation, but advanced grammar/clarity/fluency/tone suggestions (blue underlines) and paragraph rewriting are supported only in 6 languages: English, Spanish, French, German, Portuguese and Italian.

The official Grammarly pricing page (grammarly.com/plans) shows Pro only as $12 with no billing period, while the Superhuman official price table shows Pro at $15 for monthly billing and $12 for yearly billing. Some third-party sources, however, list Grammarly Pro bought on its own at $30 for monthly billing and $20 per month for quarterly billing, so it may differ by purchase route. Be sure to check the final price at checkout.
No official won price could be confirmed. The old Premium/Business plans were merged into Pro.

Which plan to choose

Free: People who only want to catch typos and basic grammar mistakes in English emails/assignments. Just installing the browser extension is quite useful.
Pro: Office workers and international students who often write English reports/papers/resumes. Whole-sentence natural rewriting and AI detection/plagiarism checks are the core, and yearly billing is much cheaper.
Business: Sales/CS teams that handle English email in bulk with Superhuman Mail in addition to Grammarly.
Enterprise: Large companies that need security policies (SSO, DLP, no data training) and want to unify the tone of company-wide documents.
API: There is no public API, so if you want to add proofreading to your own service, you need to look at other proofreading APIs.
