Master the Art of Impactful Writing

A key factor in any gripping mystery novel or suspenseful thriller is the characters. That’s why AutoCrit helps you craft compelling dialogue that brings your characters to life – instead of burying their potential under needless tags and overblown adverbs.

And when you’ve put so much effort into building your complex schemes and shocking revelations, they deserve the chance to make the proper impact. Take your prose from purple to polished in one smooth sweep by eliminating unnecessary filler, wiping out off-putting repetition, and making sure your story is paced to perfection – so readers can’t pull themselves away until the answers are revealed.


“For in-depth analysis of your prose, AutoCrit is a great tool that will open your eyes to a lot of literary styles and techniques; even if you are a seasoned writer.”

–Kate Russell

Frequently Asked Questions


Q: Who would benefit from AutoCrit membership? 

A: AutoCrit is specifically designed for fiction authors who want to cut down the time and stress involved in producing a professionally edited manuscript, without compromising on the quality of their work or their creative vision.

Q: I already have a human editor I trust with my work. Would AutoCrit still be helpful? 

A: Yes! When you revise your draft with AutoCrit first, you’ll give your editor a much cleaner manuscript. That means he or she can stop focusing on nitty-gritty details like how many adverbs you’ve used (almost always too many) and start looking at the bigger picture, helping you tune your storytelling to perfection.

We love human editors (in fact, quite a few use our software!), so it’s our goal to make sure you have the best, most rewarding experience working together.

Q: I’ve worked hard to develop my voice as a writer! Will AutoCrit take that away? 

A: Absolutely not. AutoCrit produces recommendations based on style guidelines and trends in published fiction, but you’re always in control as the author.  There are no hard rights or wrongs, here, so simply ignore any recommendation that doesn’t work for you.

Q: What if I get stuck figuring out the features of AutoCrit? 

A: For the best possible user experience, AutoCrit includes a full suite of guides for its features, explanation of how to interpret each analysis and dedicated support via email. Not only that, but AutoCrit members also gain access to helpful explainer videos and regular custom articles on the craft of writing.

Q: What kind of tech do I need to use AutoCrit? 

A: AutoCrit is an online web-based software. You can use it from any internet-enabled device, though a laptop or desktop PC/Mac is recommended.

Q: What if I’m not ready to edit yet? 

A: The real question is: Why aren’t you editing already? Whether you’re a pantser or a planner, with AutoCrit you can edit chapter by chapter, improving as you go. As your proficiency increases thanks to AutoCrit’s feedback, you’ll find yourself naturally optimizing those later chapters – giving you less and less to fix. By the end, you’ll have a completed manuscript that’s already in impressive shape… and in half the time! Why drag the process on by waiting? You’ve got more stories to write, and your fans want to read this one yesterday!

Q: What makes AutoCrit different to the likes of Grammarly and ProWritingAid? 

A: It’s really apples and oranges. Grammarly focuses entirely on spelling, grammar, and readability, but that’s only a minor part of AutoCrit. Where ProWritingAid acts as a useful style guide, it lacks the real-world data through which AutoCrit produces recommendations.

Simply put: AutoCrit helps writers quickly and easily refine their work by providing the most relevant, impactful feedback. With dynamic editing guidance that adjusts based on data from millions of published books across many different genres and bestselling authors, AutoCrit is the only online editing platform that keeps your specific needs and target audience firmly in mind.

Q: Did you REALLY scan millions of books to feed the AutoCrit Algorithm? 

A: YES! Literally millions of complete, successful published novels have been scanned and fed into AutoCrit software – the only one like it on the market. AutoCrit goes beyond the guidance found in style manuals and editing guides. Creativity meets technology in this real-world data, smartly applied for your benefit.

With AutoCrit, you can compare your work directly to real, published fiction from some of the top published authors and in genres such as Mystery/Suspense, Fantasy, Sci-Fi and Romance. With a mere couple of clicks, you can see how your writing compares to these standards – then tweak it as necessary to obtain the best chance at a successful, critically acclaimed novel… and the career to match.
