Corrigy

Corrigy is a set of English learning tools, including this extension, that helps you quickly learn English by using your written English (emails, reports, tests) as a basis for your learning. Corrigy checks your English for common and not so common mistakes made by English learners around the world. These errors then form the bais of your English Learning.

Corrigy uses a database of real world English mistakes made by English learners around the world (French, Spanish, Chinese) Developed over ten years via feedback from English teachers around the world).

Corrigy is constantly enlarging its database of English errors allowing you to learn from other people’s mistakes.
