Writing · by Superhuman (formerly Grammarly, Inc.)
Grammarly
Grammarly runs as a browser extension, desktop app and add-in, so it checks writing across email, docs and web apps. The Free plan covers core spelling and grammar plus 100 AI prompts a month. Pro adds full-sentence rewrites, tone adjustment, plagiarism and AI-text detection, one style guide and one brand tone, and 2,000 AI prompts per member per month. The company now operates under the Superhuman name, and Enterprise is sold through Superhuman Go.

Why people pay for it
- Inline grammar and clarity fixes in almost every app and website
- Full-sentence rewrites and tone adjustment
- Plagiarism and AI-generated text detection
- Style guides and brand tones for consistent team writing
- Fluency help for non-native English writers
Reasons to keep paying
The honest case for Grammarly. If these matter to you, don't switch.
- Works in nearly every text field without copy-pasting into a chatbot
- Team style guides and snippets enforce consistent wording
- Plagiarism checks against a large web and publication index
Risks to know about
- mediumsensitive data
The extension reads text in many apps; review which sites it is enabled on for confidential work.
- lowcompliance
SSO, SCIM, DLP and BYOK are Enterprise only.
- data portability: easy
Your writing stays in the apps you use. Style guides, snippets and brand tones would need to be recreated elsewhere.
