Grammar help that improves how English sounds
Diglot catches grammar problems and helps you rewrite sentences so they read naturally for academic, business, and everyday writing.
Diglot focuses on clear output, not only error detection, so you can act on better suggestions right away.
The workflow is designed around mistakes common to non-native speakers, including article, preposition, and phrasing issues.
Use one pass for correction, rephrasing, and confidence before sending or publishing your document.
How this workflow works
Move from bilingual rough ideas to polished English in one calm flow instead of stitching together separate tools.
Draft naturally first
Write your paragraph without stopping for every small error or awkward phrase.
Scan inline issues fast
Diglot marks spelling, grammar, punctuation, capitalization, and style issues directly in the editor.
Fix what matters most
Accept one suggestion, ignore a rule, or correct multiple issues at once without losing your place in the draft.
Use grammar as part of revision
Turn grammar review into a drafting step instead of a separate proofreading session at the very end.

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.
