How it works
The free plan covers basic checks, with Premium at $6.67 a month on annual billing for unlimited checks and advanced features. It is built for researchers, students, and technical writers who need more than a general grammar checker.
Trinka is a strong choice for academic writing, especially for researchers in technical fields. It will not replace a full writing assistant like Paperpal, but for grammar and style checks that understand academic conventions, it is one of the best tools available.
