What is Trinka?
Trinka is a privacy-first grammar checker and writing assistant built specifically for academic and technical writing, from Enago (Cactus Communications). Beyond basic grammar, it offers a subject-aware "Power Mode," style-guide-based corrections (APA, AMA, ACS, AGU, IEEE), paraphrasing, consistency checks, citation tools, and plagiarism/AI-content detection reports aimed at researchers rather than consumer writing.

Confidential Data and Enterprise plans are custom-priced for institutions.
