LanguageTool plans & pricing
| Plan | Monthly | Annual | Billing | Notes | Source |
|---|---|---|---|---|---|
| Free | $0 | — | flat | 2,000 character limit per text field. Basic grammar/punctuation/spelling checks, personal dictionary, text statistics. Browser add-on available. | languagetool.org |
| Premium | not priced monthly | — | flat | monthlyUsd set null on re-verification (2026-06-16): the prior $4.92/mo ($59/yr) figure conflates LanguageTool's EUR annual rate (€59.89/yr) with USD. The official page geo-serves EUR and the help page is 403; independent USD sources disagree — spotsaas/stackscored cite ~$7/mo annual ($84/yr), other reviews cite $4.99/mo annual and $4.17/mo only on the 2-year plan, with $19.90/mo month-to-month. No single confirmable USD annual figure, so monthlyUsd is null pending a directly verifiable USD price. Premium includes 150,000 character limit per text field, 20,000+ additional style/grammar checks, unlimited AI sentence paraphrasing, style guide for custom rules, all languages and dialects. 14-day money-back guarantee. | languagetool.org |
