Trinka AI
AI grammar and style editor for academic, technical, and professional writing in multiple languages
Overview
Trinka is a writing correction and improvement tool focused on grammar, style, coherence, and language inclusivity in academic, technical, or professional texts. The free plan offers 5,000 words per month, sufficient for a student or occasional writer. Premium (€6.67/month) and Premium Plus (€10.41/month, €125/year) plans add plagiarism checks, AI-generated content detection, and increased word allowance. The Confidential plan (€41.67/month billed annually) guarantees immediate data deletion and no AI training on submitted documents, for privacy-conscious organizations.
Trinka targets primarily English-speaking universities and organizations: its interface and documentation remain exclusively in English with no French localization. A documented public API allows schools to integrate Trinka into their learning management systems. GDPR compliance is listed among the tool's certifications, but the data-hosting location (United States or Europe) is not specified publicly. The Premium Plus tier remains highly affordable for an SME or freelancer compared to professional editing services, though the tool performs less well on creative writing than technical correction.
Our verdict
Best for researchers, students, and consultants who produce many technical or academic texts and want precise automated proofreading on a tight budget. Not for you if you need to rework tone or overall text structure: Trinka corrects and improves but does not rewrite.
