Use tool ↗About Trinka AI
Trinka checks academic and technical writing rather than general prose. Alongside grammar it flags academic tone, subject-specific usage and the conventions journals expect, and bundles plagiarism checking, AI-content detection, paraphrasing and citation help. It runs as a web editor, a Microsoft Word add-in for Windows and Mac, browser extensions for Chrome, Firefox and Edge, a Windows desktop app with an offline checker, and an enterprise API. It is made by Enago (Crimson AI) in India. The free tier caps writing assistance at 5,000 words a month; a $300-a-year Confidential Data plan promises real-time deletion and no training on your text.

Pros & cons of Trinka AI
For a thesis or a journal submission this beats a general grammar checker, because it corrects toward academic register and subject conventions rather than plain readability. The privacy posture is unusually concrete: a paid tier that deletes text in real time and states no training on your content, with SOC 2, HIPAA, ISO 27001 and GDPR claims behind it. The pricing page is the weak point, listing quotas but not prices for the individual tiers.
Pros
- Corrections tuned to academic and technical register, including subject-specific usage
- Plagiarism and AI-content detection bundled rather than sold separately
- Word add-in, browser extensions, web editor and an offline Windows checker
- A paid tier that commits to real-time deletion and no training on user text
- Enterprise API and SDK for integration
Cons
- Individual plan prices are not printed as figures on the pricing page
- Quota limits on files, pages and AI requests apply on every tier
- General-purpose and creative writing is not what it is tuned for
Best for
- researchers preparing journal manuscripts
- non-native English academic writers
- institutions needing a confidential-data writing tool
Not for
- marketing and creative copy, where the academic register is wrong
- anyone who wants prices visible before signup
Watch out: The no-storage, no-training promise is attached to the Confidential Data plan, not to the free or standard Premium tiers.
