Trinka AI
Trinka AI is a writing assistant built for academic and technical English and Spanish. It checks grammar, tone, and style guide rules, then adds paraphrasing, file proofreading for Word and LaTeX, plagiarism scores, and AI content detection in one dashboard. You can start on a free Basic plan or plug it into Microsoft Word, browsers, and LMS tools.
General grammar apps flag typos. Trinka targets publication-ready academic copy with style guide modes for APA, AMA, ACS, AGU, and IEEE, plus inclusive language and consistency checks that catch subject-specific phrasing other checkers miss. Premium Plus bundles 240 pages per year of standard plagiarism and AI detection, while the Confidential Data tier adds real-time deletion and compliance with SOC2, HIPAA, ISO, and GDPR.
Researchers, students, and editors at universities use Trinka to polish theses, journal submissions, and lab reports. Institutions can buy team plans starting at six seats, and non-native English authors lean on its subject-aware suggestions before sending work to reviewers.
