Overview
Grammarly has helped people write since 2009 and its parent company rebranded to Superhuman in 2025 after acquiring Superhuman Mail and Coda. The Free plan includes 100 AI prompts, Pro is $12 a month with 2,000 AI prompts, rewrites, tone adjustment and plagiarism and AI detection, and Enterprise adds BYOK encryption, custom roles and data loss prevention. Grammarly's SOC 2 Type 2 report covers security, privacy, availability and confidentiality. It is an editor first, so it will not produce long structured articles from a brief the way dedicated generators do.
Our verdict
Grammarly is the easiest everyday writing assistant to adopt, and its SOC 2 Type 2 report helps in business settings. It edits well but is not a content production engine.
Best for
Anyone who writes daily and wants editing, tone control and AI help in every app.
Avoid if
You need a tool to produce full SEO articles or campaign copy at volume.
