Proof Mango is an editing service for online course creators.

Your course is brilliant — we make sure you sound that way.

We correct grammar and format, but we also make sure the message and flow of your course is clear.

And because we're also passionate digital marketers, we do a deep dive to make sure everything in your course works. (We check all the tech.)

Course Creator

Here's what we check your course for:

Grammar

We check for punctuation, grammar, margins, consistency, and format, among other things. We make sure your copy is polished.

Message & Flow

Is the message of your course coming across clearly? Will your students "get" what you're saying? We offer more than just grammar and punctuation editing — we make sure your message is clear.

Functionality

Do your videos get cut off too early? Are your images displaying on your landing pages and in your emails? We check that out, too.
