Trinka review

Trinka is the specialist for academic English. Its checks follow APA, AMA, ACS, AGU and IEEE style guides, and it adds technical spell check, consistency checks and inclusive language checks that general tools skip. Premium, at $48 a year, opens full writing assistance, all paraphraser modes and proofreading of Word and LaTeX files returned with tracked changes. Premium Plus at $75 a year adds file translation into 30+ languages and 240 pages a year of standard plagiarism checking. Researchers handling sensitive material can buy the Confidential Data plan at $300 a year, which includes an offline grammar checker, instant data deletion and no AI training on your text. The free Basic plan allows 5,000 words a month, which covers a short paper but not a thesis. Plagiarism, AI detection and citation tools mostly run on credits. For journal papers written by non-native authors, it is the best value here.
