LanguageTool pricing
Free plan + paid plans. There is a free plan. The plans as LanguageTool’s own site listed them on October 7, 2026, in US dollars:
- Free
- Premium: $24.90 a month
- Premium: $49.90 a quarter
- Premium: $69.90 a year
- Premium: $119.80 custom pricing (2-year plan)
USD from the store's Recurly plan objects "languagetool-premium-*-global"; their PLN figures (49.90/99.90/149.90/249.90) match what the pricing page shows in Poland, but the page itself only rendered PLN, so the USD a US visitor sees is not directly confirmed. Teams priced per seat.
