Consistency Checker—A Free Proofreading Tool


by C. K. MacLeod


Have you discovered the Google Docs library of Add-ons?  They work like plug-ins and they can perform a variety of useful tasks.

Consistency Checker, by PerfectIt, is a lite version of one of my favourite proofreading tools. It will scan your document for:

  • abbreviations in two forms (US vs. U.S.)
  • common typos (teh vs. the)
  • contractions (contractions aren’t used in all kinds of writing)
  • hyphenation of words (in-line vs. in line)
  • numbers in sentences (spelled out or numerals?)
  • spelling variations (colour or color)

These are some of the items a copyeditor or proofreader will typically check in a manuscript.

Where to Get Consistency Checker

If you have a gmail account, you can get Consistency Checker through Google Docs:

  1. Click on the Add-ons tab in Google Docs, click on Get add-ons and search for the Consistency Checker by PerfectIt. Download the add-on.
  2. Open the Consistency Checker by once again clicking on the Add-ons tab in Google Docs. The Consistency Checker should now be listed.
  3. Click Open and then click Scan.

Interpreting Consistency Checker's results takes a bit of practice and may require you to look up a few things in a style guide, but once you have the hang of it, you can use this proofreading tool before you share your writing with the world.
