What Slick Write is
Slick Write is a free web writing checker for grammar errors, possible style problems and other characteristics of text. It is presented for bloggers, novelists, SEO professionals and students. Analysis tools cover critique, sentence structure, quotations, vocabulary variety, and the flow of sentence and word lengths. A word-association tool learns contextual links from literature, and the service warns that results may be offensive. Slick Write works in a browser and through Chrome or Firefox extensions; no software download or installation is required. Each submission may contain up to 200,000 characters, approximately 30,000 words, and longer text may be trimmed. Documents can be saved automatically in browser local storage, though the site advises against relying on that for storage. The homepage says documents are not redistributed. Its privacy policy says personal information and log data may be collected, with cookies and analytics used, and reasonable security practices pursued without guaranteeing absolute security. The policy was updated October 07, 2017.
