About Grammarly
Grammarly is an AI writing assistant that checks and rewrites text. It proofreads for grammar, structure, and clarity, rewrites paragraphs, and suggests tone changes to fit a message's context or a brand style guide. It also includes a Humanizer agent, which adds personality to writing, and an AI Detector agent, which flags AI-generated text and areas to revise. The homepage describes the tool as working on any app or website.
The free plan lists 100 AI prompts for text generation. The Pro plan lists 2,000 prompts, and the Enterprise plan lists unlimited prompts. Confidential mode, data loss prevention, and granular roles appear only in the Enterprise plan. The homepage states that Grammarly does not sell or monetize user content, does not provide it for advertising, and does not allow third-party service providers to train their models on it. This is the company's stated policy, not a guarantee. Pricing is not confirmed in the source.
