What Trinka is

Trinka is an AI writing assistant tuned for academic and technical English: grammar, subject-aware checks, citation helpers, and file proofreading for manuscripts.

It sits closer to Paperpal than to Grammarly’s consumer default. Power Mode and style-guide corrections are the reason researchers pay.
