Uses LanguageTool's free public checker — your text is sent to languagetool.org to be checked. Up to ~15,000 characters, fair-use rate limits apply.

Count words, characters, sentences and paragraphs, with reading time.

Convert text to UPPERCASE, lowercase, Title Case, camelCase and more.

Compare two texts for overlapping phrasing — checks them against each other, not the internet.

Pull out the key sentences from a long text, or do a basic word-swap rewrite.
