Get publication-ready documents that match the caliber of your work—
without sacrificing your time or energy.
When you are too close to your work, your brain reads what you meant, not what it actually says on the page.
You've read your own writing seventeen times. You've sent it to someone else for "one last look." And you're still not sure if it's ready—or if there's a glaring mistake you're too burned out to catch.
You want to:

I use a tight proofreading process that checks structure, consistency, and technical integrity—not just spelling and grammar, like ChatGPT.
This is the same rigorous proofreading process I've used for a decade to deliver error-free, publication-ready documents for finance professionals, marketing agencies, technical writers, and communications directors who produce high-stakes documents.
And now it's available to help you ensure your documents read clean, hold up under scrutiny, and don't come back to haunt you.
Here's everything you get when you hand off your document:
You receive your proofread file back in as little as 24 hours. It will contain tracked changes or highlighted notes so you can see what was fixed, and a clean version you can confidently publish or send. You'll also receive a brief note with suggestions for further improvement in style or tone.
You can always reach out with clarification questions on any note or edit.
It's time to hand off your document, take a deep breath, and get back a version that's polished, consistent, and ready to represent your work.

Read the Reviews ↓“Great job! Fast response and helpful advice! We had a 50-page technical Offering Document that required edits. Turned the entire document around in under 24 hours. I would use Josiah again for future projects.”

“Josiah is an amazing communicator, works super fast, and very nice. I was impressed with his ability to turn around our project very quickly.”
“Josiah is by far one of the most highly skilled wizards of the English language I’ve ever worked with. He’s able to edit, proof, and write all sorts of content from technical to marketing. I hesitate to give him a glowing review because he’ll get so much work that he’ll forget about us!”
“Josiah was a copy rockstar! He not only proofed the standard things (grammar, punctuation, etc.) he made recommendations for making the copy stronger. He also quickly learned the conventions of the client and was able to carry them forward. I felt very confident in the work after it had been proofed by Josiah.”
“Great and accurate job editing a security IT book. Not an easy topic with some challenging computer code. He understood and followed the writing “spirit” and managed to get it just right! Totally satisfied—thank you, Josiah!”

When I hire him, I know I have someone partnering with me to achieve the highest quality end result. Needless to say, Josiah has become my go-to freelancer when I have a copyediting/proofing project.”

He is direct in answering questions and providing feedback. I would definitely recommend him to anyone in need of some proofreading.”
“Josiah was GREAT to work with! Not only is he a meticulous editor, but he provided suggestions that I hadn’t even thought about that improved the product. He was very intuitive about how to get the job done properly. Josiah also communicated with me in a timely manner, and stayed right on schedule so that the job was completed on time. I highly recommend Josiah and will definitely hire him again!”
“I’ve worked with Josiah on several big editing projects and he always exceeds my expectations. His work is thorough and impeccable. I’ll be hiring him again!”

“Josiah’s work was thorough, on-time, and thoughtful. He delivered good work on this project and was professional and easy to work with. His review of our alumni magazine caught errors we had missed.”
“Josiah did a great job editing our investor letter. His editing skills show that he is not only optimizing for syntax and grammar but also flow and clarity of the content.”
Backed by a satisfaction guarantee and a missed-deadline refund.
A decade ago, I noticed that work from extremely intelligent, hard-working people was being undermined by preventable errors. Decades of expertise down the drain due to a dumb typo.
I believe work worth doing is worth doing well—and I'm highly qualified to proofread, having studied writing under instructors from Harvard, MIT, and Yale. So I built a business around ensuring that your documents match the caliber of your work.
I'm the last line of defense for busy professionals.
I'm the proofreader people call when errors are disqualifying. One client says I've "saved her professional career on more than one occasion."
My clients get real human judgment—and practically perfect documents.
I become an instantaneous subject matter expert, then catch the typos and context-dependent errors that no tool can find and most other humans miss. You can send a document that fully reflects the quality of your expertise, not your exhaustion.
