Full review
Trinka is an online grammar and language tool aimed squarely at academic and technical writing. Built by Crimson's AI team in Mumbai, it catches the formal, subject-specific mistakes that general checkers skim over, and goes further with tone, conciseness and word-choice suggestions drawn from editor and linguist expertise.
There's a genuinely useful free plan (5,000 words a month with advanced checks), and Premium runs around $6.67 a month when billed annually, undercutting most Western rivals, which makes it an easy pick for Indian students and researchers. Plagiarism checks, a Word add-in and browser extensions round it out.
