ToolifyNav verdict
LanguageTool is the multilingual proofreading workhorse in this Writing pair: broader language coverage than many US-centric grammar apps, lighter than a full AI author. Grammarly remains the mainstream rival; LanguageTool often wins Europe and multi-language shops. Turn on Premium only if advanced rules and paraphrase volume show up in your weekly writing, and keep a human final pass on legal or medical text.

About
About LanguageTool
LanguageTool is a multilingual writing assistant for grammar, punctuation, style, and AI paraphrasing. It ships as a web editor plus add-ons for Chrome, Edge, Firefox, Opera, Gmail/Outlook, Google Docs, Word, Apple Pages, LibreOffice, and desktop apps. Free checking covers solid baseline corrections; Premium unlocks tens of thousands of additional rules for major languages, much longer character limits (up to around 150,000 characters per field), unlimited AI paraphrasing, and custom style-guide rules.
Pricing often runs promotional discounts on Premium personal plans; business tiers emphasize GDPR-conscious team deployment. Exact current Premium euros/dollars should be confirmed on languagetool.org because countdown promotions are common. LanguageTool competes with Grammarly, ProWritingAid, and Wordtune — frequently preferred by multilingual Europeans and privacy-sensitive teams who want strong non-English coverage.
For ToolifyNav Writing it is the multilingual correctness layer beside Byword's bulk SEO article factory. Public positioning was cross-checked against the official site and recent third-party summaries at harvest time. That mix of open cores and paid polish is why it still shows up in many editorial workflows.
