Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Trinka is an AI-powered grammar checker and writing assistant for students, researchers, academics, and professionals working on academic or technical content. It checks grammar, spelling, punctuation, sentence structure, word choice, and style, while also supporting paraphrasing, citation checking, consistency checks, and AI-assisted writing. English and Spanish grammar checking are supported, with US and UK English variants for English content. Its web editor, browser extension, Microsoft Word add-in, Windows application, and file proofreading tools suit document-heavy workflows.
The published plans show a useful free entry point. Basic costs $0 per month and includes 5,000 words per month, lite grammar checking, browser extensions, and limited AI writing requests. Premium adds unlimited writing assistance, advanced editing modes, style-guide corrections, and a Windows desktop application. Premium Plus adds premium features, 240 pages per year of standard plagiarism checking, file translation from 30+ languages, and up to 240 proofread files per year. Confidential Data costs $300 per year and adds an offline grammar checker app, instant data deletion, no AI training, and 1,000 plagiarism or AI-detection pages per year.
Trinka stands out when the workflow extends beyond basic proofreading. It supports Microsoft Word, Microsoft Outlook, Google Docs, Authorea, Evernote, Medium, and LaTeX, while its API and self-hosted options can fit more structured or controlled environments. Style-guide corrections and consistency checks cover spelling, hyphenation, numbers, and symbols, which is useful for formal documents that need more than sentence-level fixes. Choose Trinka for academic, research, technical, or citation-focused writing. A different grammar checker may suit users who need a native mobile app or a simpler general-purpose writing tool.
