What Slick Write is

Slick Write is a writing checker that looks for grammar errors, possible style problems, and other features of written text. It offers analysis tools for critique, sentence structure, quotations, vocabulary variety, and the flow of sentence and word lengths. Its word association tool draws on literature for contextual associations; the service cautions that results may be offensive. You can use Slick Write on the web or with a Chrome or Firefox browser extension, without downloading or installing software. The Free plan costs nothing and allows submissions of up to 200,000 characters, approximately 30,000 words; longer text may be trimmed. Documents can be automatically saved in browser local storage, but Slick Write advises against relying on that as storage. Its homepage says it does not redistribute users’ documents. Its privacy policy says personal information and log data may be collected and that cookies and analytics are used. The policy also describes reasonable security practices but does not guarantee absolute security, and identifies RussTek LLC as the site operator.
