While there's no substitute for a human editor, there are some wonderful tools which can not only help you save money and time with your editor by presenting them a cleaner manuscript from the start, but which can also help you identify patterns of error and weakness in your writing. Once you know those patterns, you can improve your writing as a whole.
The three tools above (the pictures are linked to their product pages) are the ones I use on a daily basis when writing, revising, and editing. Let's dive a bit deeper into what these are and how I use them.
While I don't really do resolutions, I do need to get back to Book 3 of The Olivia Chronicles. One of the struggles I have with longer works like novels is dealing with chapters and organizing everything in one large document. I suspect that Scrivener will help me with this. I'm also working on an article related to literacy, and I can see where this will help me with source material and research organization.
They are offering a free trial right now, so if you're interested in trying it out, what have you got to lose? And, check this out: It is a true 30-day trial. As the site indicates, if you only use it twice a week, then you'll be able to use it for 15 weeks for free--how cool is that? I suspect if you watch the introduction video above you'll be pretty jazzed about the software, too.
