Pricing Issues Reported by Users
LanguageTool browser extension is no longer free
LanguageTool made its browser extension Premium-only, saying most of its 6 million extension users were free and server costs had become unsustainable. After a 14-day Premium trial the extension stops underlining errors and paraphrasing for free users; only the website editor stays free. Add-on store reviews turned sharply negative and many users moved to Harper or QuillBot.
Why is LanguageTool Premium so expensive monthly?
In the US, Premium lists at $24.90 a month paid monthly versus $69.90 a year ($5.83/month) on the annual plan, so monthly billing costs about four times as much. The checkout often shows a 20% 'limited-time' discount, and a pricing tracker logged the discount being removed in August 2026, so the price you see depends on when you buy.
LanguageTool free version limits: 2,000 characters and 3 AI rephrases a day
The free Basic plan checks up to 2,000 characters per text field (Premium: 150,000) and allows 3 AI sentence rephrases per day, with Picky mode limited. Combined with the extension paywall, free use now means copy-pasting short chunks into the web editor.
