Purpose

LanguageTool provides multilingual grammar, spelling and style checks and describes AI sentence rephrasing, with web-editor, browser, office-plugin and desktop entries.

Features described on the official site

  • Proofreading covers spelling, grammar, punctuation, casing, redundant wording and style suggestions.
  • AI paraphrasing describes more formal, fluent, simple or concise sentence variants.
  • Web, browser add-ons, office integrations such as Google Docs/Word and desktop apps have separate entries; the site lists grammar checking across languages and dialects.

Suggested starting workflow

  • Choose language, dialect and target style while retaining the original and specialist terminology.
  • Select a web or add-on entry and review permissions, text-retention rules and plan limits.
  • Inspect each correction and rewrite; independently check facts, quotations and specialist judgments.

These are editorial starting suggestions based on product purpose, not workflows tested by this site.

Before you use it

  • Not tested hands-on here; feature descriptions come from official material.
  • Pricing, regions, languages, commercial use, watermarks and export conditions have not been verified for a single plan.
  • Multilingual grammar checking does not establish identical AI paraphrasing for every language. Free basic checks, Premium suggestions and unlimited rephrasing are separate. Browser no-text-storage claims do not extend to the account editor that saves texts. Claims of finding every error are not accuracy evidence from this site; no add-ons were installed or text submitted.

Pricing & plans

Plan pricing has not been checked. Verify it with the provider; a starting price may not cover your task.
