[This guest post was written by Amy Cowen, a writer who learned a lot about online proofreading tools while editing her own articles. Today Amy is happy to share a few tips with you.] Proofreading software saves you time in two ways. Firstly, it picks up on the easy mistakes. That is why most people run a spelling and grammar check as soon as they finish their work. The second time you use it, you do so to double check your changes near the end of the final draft. You check for places where you may have repeated yourself or cut a line short without realizing. Here are three proofreading programs and services that you can access online to save yourself a little time when proofreading. Proofread By GrammarBase This highly-rated tool helps you manually proofread your own work. It's a web-based tool, which means there is no downloading and the computation is done on their server. It will work with most of the popular web browsers and you may either copy and paste the text onto the screen, or you can upload the file to Proofread and have it checked that way. (Depending on length, you may be required to upload the document). Proofread will tell you how many critical mistakes you have made. These are mistakes that could potentially make your work appear of lower quality. As you know, a simple grammatical mistake may change the point of what you are saying entirely. It will then give you suggestions for things you can change within the text. Like any spelling and grammar program, you do not have to accept any of the suggestions.
