Trinka

Trinka is an AI writing assistant from Crimson AI, the technology arm associated with Enago, a long-established author-services company for researchers. Where general grammar tools target emails and blog posts, Trinka is trained for academic and technical prose: manuscripts, theses, grant applications, medical and legal documents. It flags subject-specific usage, formal tone problems and inconsistencies that a general checker might miss.

Writing modes and style-guide checks support APA, IEEE, ACS and AGU conventions. Beyond grammar and spelling, Trinka checks consistency of terms, numbers and spelling variants across a document, offers an inclusive-language check and technical checks, and includes a paraphraser, an academic phrasebank and AI-assisted writing. Proofread File lets you upload a whole Word document and get it back with tracked changes; a LaTeX proofreader handles TeX sources. Citation tools check reference quality and formatting, a journal finder suggests suitable venues for a manuscript, and plagiarism and AI-detection reports help authors check work before submission.

Trinka runs in the cloud, as a Word add-in, a browser extension, Windows and offline desktop apps, and through an API or on-premise deployment. Its Confidential Data plan deletes text in real time and excludes it from AI training, aimed at authors with unpublished or proprietary material. Universities and publishers license it for students, editors and journal workflows.
