1Checker Review

1Checker is designed to solve all these problems. Recently launched by Greedy Intelligence ®C a company dedicated to NLP and applied linguistics technologies, it is the automated all-in-one proofreading solution for Windows users, offering spell/grammar/punctuation checking, vocabulary enrichment, dictionary, translation and much more.

In addition to its Windows 8 app, the newly launched full PC client version (for Windows 7, Vista, XP) can be your alternative choice for writing enhancement with more features and full support, free of charge.

Based on core engines and patented algorithms, 1Checker mainly does proofreading work, tempting to aid you finding writing issues, suggest corrections, give in-depth explanation and detailed examples, and enhance word usage anywhere, any time.

Beside proofreading, dictionary and translation gadgets can assist you in a swift way. At the end of your writing, 1Checker will give you a general evaluation on your word usage and sentence structure. It's mentioned that all these functions can be used in ONE panel from 1Checker.

Regarding the proofreading effect, there is a saying that fact speaks louder than words. Compared with Microsoft Word's spellchecker, 1Checker can do much more.

We've found 1Checker to be accurate for most writings. We do note that 1Checker should be considered a helpful writing tool as it incorporates grammar, spelling, word choice, and style, but not the author's arguments, logic, organization, and ideas. The latter will still need to be examined by a human.

Writers, bloggers, those who email a lot, those with English as a second language, etc.
