1Checker is the automated all-in-one proofreading solution for Windows users, offering spell/grammar/punctuation checking, vocabulary enrichment, dictionary, translation and much more. 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. 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. Stay tuned for more to come - 1Checker Web, Plugins, our Online Community and User Center, etc. Start your proofreading experience for FREE now.
