After hearing so many good things about this software, I finally decided to start working with Antidote.
Antidote is an advanced French text checker. It features a very powerful spell/grammar checker, and incredibly complete dictionaries and style guides. Compared to the other checking solutions, the spelling and grammar check tool of Word for example, it does a better job at finding mistakes, even for complex grammatical structures.
The great thing about Antidote is that it also analyses your texts more deeply than any other tool. It will for example make style suggestions (regarding the use of certain expressions, commas), detect false friends and make suggestions of words you can use instead…
So that’s really a great tool for a translator. Even after using conventional tools and carefully proofreading your texts manually, it just happens that you didn’t notice a mistake, or used a word in an inappropriate way. Antidote detects most of these and helps delivering more professional documents.
