Trinka AI is an online grammar checker and language correction AI tool designed for academic and technical writing. It is designed to detect errors that other grammar checker tools miss, such as subject-verb disagreements, syntax, word choice, pronoun and article usage, as well as technical spellings. It also has features that go beyond grammar and spelling, such as style guides, formal tone, technical word choice, and conciseness. Trinka has learned from the best-written papers in every subject to give users the best suggestions. It is suitable for a range of fields such as medicine, biology, physics, social sciences, engineering, chemistry, geology, computer science, and economics.
