Key differences
- LanguageTool's main strength is language coverage: it checks grammar, spelling and punctuation in 30+ languages.
- Trinka is tuned for academic and technical writing, with support for style guides such as APA, AMA, ACS, AGU and IEEE, a Journal Finder and a citation checker.
- The free plans are limited in different ways: LanguageTool caps each text at 2,000 characters, while Trinka caps use at 5,000 words a month in Lite mode.
- Trinka's plagiarism checks and AI-content detection use credits on top of the plan, and its shown prices are discounts against higher list prices, so renewals may cost more.
- LanguageTool's monthly Premium (€20.14/month) costs far more per month than its yearly plan (€60.62/year).
