About Us

What is Twin Tweaks Editing?

When you've poured everything into your book, the last thing you want is for your readers to comment on typos, continuity conflicts, grammar mistakes, or bad facts. That's where the partners at Twin Tweaks Editing come in. You write it, then tell us what you need. We'll read your manuscript and make suggestions that you can use or toss out -- YOU are the author after all! Our goal is your satisfaction and we strive to make sure your publication prompts great reviews from your readers.

Please take a look at our site to learn more about us and what we offer, then give us a shout when you're ready to have the tweaking experts join your team. We are committed to you, your vision, and your readers.

In general, a copyedit focuses on language and style improvement. We look for clarity (word choice, phrasing, sentence structure, repetition, and rhythm) and basic fact-checking, in addition to responsibilities performed in our proofreading stage. However, we want to make sure to meet our authors' needs so we offer copyedit levels ranging from $3-4 per 1000 words. We simply ask that you submit your first 25 pages or so for us to review. Then we can provide you with the appropriate price per 1000 words and an idea of what we plan to specifically focus on while we copyedit your manuscript.


After you've had your manuscript copyedited and have made your revisions, we can perform a post-copyedit read that focuses on spelling, grammar, punctuation, consistency, and readability for $2.75 per 1000 words. If you used our copyediting service, feel free to let us know if you'd prefer to have the same person do the proofreading, or if you'd like a fresh set of eyes and perspective.


Already been through both copyedit and proofreading stages but want one last look over your manuscript before calling it complete? That's what a good polish is for. At this point, your manuscript has been through all of the big changes and for $2.50 per 1000 words, we will read through looking for any glaring mistakes, typos and formatting errors.

The Twin Tweaks Advantage
There are two of us...

We have twice the capacity to meet your needs.

If you want a second read, you can avoid the time and hassle of searching for another editing company.

Optimized Output

Need the manuscript returned in a specific format? No problem. Whether it's marking up a hard copy or tracking changes in Word, we can tailor the output to your needs.

Additional Work

Need something other than a manuscript edited (résumés, dissertations, grant proposals, etc.)? Contact us for a custom quote.


I've used Twin Tweaks for a polish for a book that had already been professionally edited-and they found A LOT. On the flip side, I've used a different proofreader for a book Twin Tweaks edited first-and they found nothing. That says a lot to me.

Mara Jacobs,
a New York Times and USA Today Bestselling Author

I've worked with Twin Tweaks on several books, and Ashley and JoAnn have always provided prompt and friendly correspondence and superb editorial comments. Twin Tweaks is an invaluable part of my publishing business, and I look forward to working with them on many books to come.
