Chicago Manual of Style comes to PerfectIt 5

I honestly didn’t see how PerfectIt 4 could be improved upon. I’ve been using it since it came out. And I used PerfectIt 3 before that. I love, love, love this program.

Believe me when I say that Daniel Heuman and the team at Intelligent Editing have found a way to improve upon it.

When you get PerfectIt 5, you’re not only getting the kind of proofreading/copy editing support you’ve become accustomed to in the past, but if you have a subscription to CMOS online, then you’re also getting real-time support via the site ( When PerfectIt5 highlights stylistic problem areas, it also provides you with a live link to CMOS guidance.

If it’s something you already know and are comfortable with, something you’re sure about, of course you can ignore it and keep on trucking. However, if it’s something that makes you wonder whether you know what you thought you knew (and it happens to all of us!), just click on the link and you’ll see the “chapter and verse” about the issue. For example: “The term half brother is usually open. See more from CMOS 7.89”. Clicking the “see more” line brings up the relevant text directly from the CMOS site, with the numerals in bright red bold type.

For editors who are still learning the Chicago style, I’ll say this is nigh unto invaluable. No more wondering whether you’ve gotten it right. No more second-guessing yourself. And best of all, you’ll find you’re looking up fewer issues. Even for those of us used to using the online version, this is an improvement. The information will come up when we need it, at the precise point in our document where we need it. NB: This addition does not include the entirety of the CMOS database. There will still be times you’ll need to go to the book or the online version on your own.

The usual caveats apply as they do with any “checker” program. It’s better to be cautious and check each instance individually than cavalierly “fix all.” (Only when I can see “all” right there in one place do I ever even consider doing that.)

I say all of this as an editor who works only with fiction. I don’t have to think about heading hierarchies, tables, figures, footnotes, bibliography entries, and so on. If you do, I feel safe saying you will find this a godsend. The guidance will pop up immediately, right on your screen. No hunting through a print copy, no searching the website. It’s right there, and it will expand at the click of your mouse.

Congratulations, Daniel and team! You found a way to improve something I thought was already perfect.
