What I like most about PerfectIt is the dedication of the staff to keep making improvements, provide excellent customer service, and keep the price affordable.

Editor

PerfectIt has been an invaluable tool and the customer service has always been outstanding. It is recommended a lot in editing groups and there's a reason for that.

Owner

I've only been using this tool for a week but am already super impressed by its capabilities and ease of use. The integration with CMOS is a game-changer.

Owner and Editor

I love the addition of the Chicago Manual of Style function in PerfectIt. It is helping me catch more issues than in the past and as an editor, I'm thrilled to now have this function.

When I learned that the Chicago Manual of Style was now integrated into PerfectIt 5 it was like finding out that my college roommate had gotten married to a good friend in the neighborhood.

PerfectIt is essential for my business and the addition of the Chicago Manual of Style option is fabulous and will help me greatly in my editing business.

Freehand Book Editor

I like everything about PerfectIt, but I especially like that it checks for spelling and capitalization consistency across the manuscript. In book editing, that's very important.

translator / proofreader 

It is a great investment of you regularly produce English language texts and want to make sure your texts are of impeccable quality and consistency.

Proofreader, Editor

PerfectIt saves time and gives me peace of mind. After using it, I can rest easy knowing that my edits are the best they can be.

Senior Editor

I cannot recommend it enough for anyone wishing to easily and quickly enhance the quality of their work.

I love what it does (consistency check) and that it does it so well.

Copyeditor

Ensuring consistency in usage in long documents and books has been made easy by PerfectIt, and I always enjoy using it. It's intuitive, easy to use, and fast.

Chokes on documents with tables and graphs (I work on documents that have lots of each and removing these isn't an option).

Director

I have been impressed (over several years using the program) by the prompt and patient tech support PerfectIt has provided when needed.

PerfectIt! caught some of them. Example: yoga asana (a pose in yoga) would be yoga aasana (double a at the beginning) in the book, which should present as a spelling error.

proofreader

PerfectIt helps me do important parts of my work quickly, efficiently and without stress.

Principal

Is it the software's fault that an effort is required to do so, or my fault because I'm too lazy to figure out HOW to do so.

Advocate

Not because it is correct, but because it is a convention that 'i before e except after c' verb peckers pounce on and make life miserable for normal people with.

It’s a fantastic alternative who are familiar with Grammarly.

freelancer

I honestly recommend it, it's very helpful and easy to use.

Easy to use, integrates flawlessly. Suggestions are always helpful.

Language Analyst

It's good considering it's free and community-based. And it's perhaps the only major Grammar checking tool in non-English languages.

However, this is complaining at a very high level.

Marketing Consultant

It's not that easy to work on multiple blocks of text that you're checking from different docs. It can get confusing because it's all in one editor.

Customer Service

As other AI tools, the context might be off or missing.

Translator

It's proactive approach to autocorrection since I am currently teaching myself Catalan, French, Italian and Portuguese and I need to keep switching languages.

It integrates beautifully with Google Chrome as an extension and can therefore even help to prevent errors when simply writing a Facebook message.

Marketer 

The only bad thing is that the price is somewhat high.

Internal Auditor

Its easily integrated with other software and very easy to use.

freelance writer

Its a great software to correct my papers. Sometimes I write  quickly and I write the wrong words in the sentence.

Typing quickly without looking at keyboard and screen, knowing “LanguageTool” will identify spelling and punctuation errors, great.
