What Trinka does

Academic and technical text is the focus. The grammar checker runs in Lite or Power mode and can apply corrections based on style guides such as APA, AMA, ACS, AGU and IEEE. Consistency and inclusive language checks sit alongside it, along with a paraphraser and AI-assisted writing. Whole MS Word and LaTeX files can be proofread, not only pasted text.

Research tasks go further. A citation checker and formatter, a Journal Finder, and plagiarism and AI detection checks are included, with those checks drawing on monthly credits. Premium Plus adds file translation into 30+ languages. A Confidential Data plan offers real-time data deletion and states that user content is not used for AI training. Trinka installs into MS Word, Chrome, Firefox and Edge, and there is a Windows app and a grammar checker API.

Basic is free with 5000 words per month, Lite mode only, 5 AI writing requests and 4 credits a month. Premium costs $48 per year billed annually, with 25 AI requests, 10 credits and data auto-deletion after 90 days. Premium Plus is $75 per year billed annually, with 1,000 requests and up to 240 pages a year of plagiarism and AI checks. Confidential Data is $300 per year billed annually.
