Superhuman

Grammarly is an AI writing assistant that checks grammar, spelling, clarity and tone in the text you write. It works across apps and websites, and it can rewrite full sentences, suggest tone changes and generate text from prompts.

The product is aimed at individuals who write emails, documents, essays and posts, and at teams that need consistent writing. Its Free plan covers spelling and grammar checks, tone detection and 100 AI prompts a month. The Pro plan adds full-sentence rewrites, tone adjustment, plagiarism and AI-generated text detection, and 2,000 AI prompts per member a month.

The Enterprise plan is for larger organisations. The page describes it as available through Superhuman Go and lists features such as unlimited members, dedicated support, confidential mode, granular roles and permissions, and data loss prevention. Pricing for Enterprise is by quote through a sales contact.

Grammarly is installed as a browser extension and is also available for desktop, Microsoft Office, Google Docs and mobile devices. Users sign up with an account, then receive suggestions as they type, or they can paste text into the editor for review.

On its website, Grammarly says it does not sell or monetise user content, and that it does not allow third-party service providers to train their models on user content. The company also says its SOC 2 (Type 2) report covers security, privacy, availability and confidentiality.

The Pro plan is listed at $12 per member per month when billed annually, or $30 when billed monthly. Grammarly is now part of Superhuman, and the company is listed as Superhuman on its site.
