"Behind price, voice is the #1 concern of clients when hiring a new copywriter"

- Kevin Rogers

Master Voice

Discover what “voice” actually means (it’s not some woo-woo concept that can’t be learned) and why most clients cite this as the biggest failure of their copywriters. Learning this means more repeat work.

Build Your Guide

We'll show you how to document and create a new voice for any client—personal brand or corporate. Then we'll build your guide together, which you can customize to fit any budget.

Sell It for a Fast ROI

Not only will you walk out with a finished voice guide, but we'll also teach you how to pitch, package, and sell it to both new and existing clients. You'll have an add-on service for all your new projects.

"Now I have something really unique that no one else has in the industry and it’s given me confidence to be bolder in pitching my copy services. I've worked Codex into my copy framework (customers don't know what I do behind the scenes) and that’s led to more high ticket sales of $10K+ sales page and $50K+ copy mentorship opportunities. Thank you, Justin!"

Get Paid to Learn Your Clients' Voice

Not only will you write more authentically, you'll turn your research into a new deliverable that can (and will) create more profit.

This Private Small-Group Training Teaches You How to Analyze, Mirror, and Document Any Writing Style—a Highly Desirable Skill for Top-Level Clients

Extra revenue streams. New offers. Longer gigs. THIS is how you reduce editing time. THIS is how you eliminate back-and-forth feedback. THIS is the process that separates you from other writers. THIS is how you erase one of the biggest concerns of upper-tier clients.

"In just 4 months I've already created 3 guides and my clients have been astonished at how true to their voice and values it felt. They now feel confident explaining it to other people, and using that as a guide as they bring in others to create content for them. Justin is a fantastic teacher - incredibly giving of his time and his experience. There were no questions he wouldn't answer - he allowed us to pick his brains on strategy, pricing, how to increase value, and how to find clients. If you're on the fence about taking this course - do it! You won't regret it."

Gillian Hill
Copywriter & Editor

"I sold my first super short voice guide (a 5-pager) to a client for $3,200. I documented their voice as I went through the program and sold it them with the one simple question Justin taught us to ask. The whole thing took 5 hours and it changed their entire content production process. They couldn't thank me enough!"

Ivan Srsen

"The Codex Academy really opened my eyes to those little intricacies of voice that most writers don’t see. I have gone through the course three times already and I’m still learning."

Nicole Kolesar
SaaS Copywriter & Content Strategist

"Codex Academy transformed the way I measure and analyse voice. Now I have a rare skill set that sets me apart from 99.9% of marketers—and directly impacts the amount I can charge for every project. Most importantly, I now have a completely new deliverable that I know people need. Learning from Justin is one of the smartest decisions I've made."

Brandon Burton
Copywriter & Brand Voice Strategist

"I've written brand voice guides before and they were solid, but taking Codex Academy helped me take them to an entirely new level. I now feel confident that I can break down someone else's voice in a way that someone else can replicate it. That's a HUGE value for a certain kind of client and it's a really specialized service I'm excited to promote more. It complements my website copy services perfectly."

Erika Holmes
Website & Email Copywriter

"The Codex Academy immediately positions you as an expert. One of the biggest objections clients have about working with copywriters is the fear that the copywriter won't capture their voice. Or they're worried everything will be written as "Hey, Girl Wassupp?!". Telling clients I am a certified voice expert and that I have a process to capture their voice INSTANTLY tackles that objection. It's a great add-on to copywriting packages. Clients are delighted to see what voice-type they are, and it instantly positions you as an expert and they trust you even more. Great ROI with this course."

Kim Kiel
Direct Response Strategist and Copywriter for Ethical Businesses

"I just sold my first brand voice guide!!! The sales call I had before you 'Ask Me Anything' just emailed with a "let's go!" I'm sooo excited and so appreciative of your time and energy for us. Codex Academy is changing the course of my business and I'm so thankful to have learned from you."

Sandra Kaye
Brand Voice Strategist & Copywriter

"I just bagged a retainer client in the eCommerce/health & performance space because I nailed their quirky TOV!"
