A content editing solution for course creators

You want your online course to look perfect, but you don't have
time to obsess over every detail. You need someone to review your content with a fine-tooth comb,
so you can take ‘quality' off your plate.

“Monique from Proof Mango has become our go-to proofreader.
She's thorough and has great attention to detail,
resulting in our materials being polished.”

Did I spell that right? 🤷🏼‍♀️

You're more worried about whether your course will sell — we get it.
That's why at Proof Mango, we tackle the misplaced commas and the words
you can never remember to spell correctly.

We give every course our individual attention.

And we pretend like it's ours. Meaning, we're just as invested in this as you are.

The result?

No more cringing when a student spots a typo in your lesson presentation.
No more “I guess it's good enough” content.
No more feeling like you're “not a pro at this online course stuff.”

You can look 100% pro with clean, error-free course content.

And go back to focusing on other stuff, like student support and course sales. 💰

Proof Mango was born in Vegas

Well, technically on the way home from Vegas.

My name is Monique Muro, and after graduating from Long Beach State with an English degree in 2009, I found myself working as a virtual assistant for course creators towards the end of 2017.

On the way home from Vegas one weekend, one of my clients Skyped me, asking me to proofread his online course.

I had already been doing a bunch of editing work as well, so that was the moment I realized I wanted to combine my editing skills with helping course creators look good in their courses.

In the years since, I've both created online courses and built a steady roster of course creator clients to help proofread their content.

It's my mission to make sure course creators look professional in their courses — without having to know every grammar rule!
