An AI grammar checker for non-native English speakers needs to do more than find typos. Diglot is designed to catch the grammar patterns ESL writers face most: awkward article usage, preposition errors, unnatural sentence structure from direct translation, and tone that does not fit professional or academic contexts. Unlike basic grammar checkers, Diglot lets you fix, paraphrase, and rewrite in the same editor — so improving your grammar becomes part of drafting, not a final-pass chore.
