Description

Did that spelling mistake in your cover letter cost you the job interview? Did you annoy a client by misspelling her name? Have you edited and read over your writing 10 times but still worry that errors remain?

Proofreading is your last chance to catch errors before colleagues, publishers, application committees, and the general public read your writing. Yet it doesn't get enough attention — it's often rushed or avoided altogether. And proofreading is not copy editing. Copy editing is about significant changes to sentences and paragraphs. Proofreading is about polishing your documents to impress readers with pristine prose and design.

This course is for writers and editors of any genre who want to develop their proofreading skills and prevent embarrassing errors in written documents.

First, I explain how to develop the right mindset to catch errors.

I then show where most errors lurk.

I examine the most common errors in words, punctuation, and design.

I provide unique techniques for making your proofreading work easier and more effective.

The course now includes lessons on how A.I. has changed the proofreading workflow and how to use A.I. as a final proofreading pass, with a real-world example using a professionally edited book manuscript. You'll see the right way to integrate A.I. into a human-led proofreading process: not as a replacement, but as a powerful last line of defence against errors that even experienced editors miss.

These tips come from my 20+-year career in editing and proofreading. I've edited thousands of written documents and use these techniques every day.
