I hesitated before bought because I already had an excellent digital dictionary (Grand Robert), but Antidote is not a duplicate: it is above all a very sharp analysis software of your texts, and a valuable aid to writing.

The fact that it automatically integrates with word processing software, browsers or email clients is a real plus for natural use.
