Josiah edited a 47-page instructional booklet for me. He has a keen eye for detail and made excellent suggestions. He works quickly without sacrificing quality of work. I hired him for a second job as soon as this job was finished. Excellent!

Get that error-free feeling—
and priceless peace of mind.

I use a rigorous proofreading process that checks structure, consistency, and technical integrity—not just spelling and grammar, like ChatGPT or other automated writing tools.

Here's everything you get when you hand off your document:

Line-by-line, cover-to-cover proofread Spelling, grammar, punctuation, capitalization, hyphenation, internal logic, and word choice errors.
Formatting and layout review Pixel-level consistency in headers and footers, spacing, bullets, fonts, margins, page numbers, and visual design.
Style guide enforcement Your brand voice, tone, and terminology remain consistent document-wide.
Technical accuracy checks Testing links, verifying citations, checking cross references, looking up phone numbers, and confirming figures.
Light editing for clarity Tightening phrasing and fixing awkward sentences, without altering your voice.

In as little as 24 hours, you receive your proofread file back with:

  • Tracked changes or highlighted notes so you can see what was fixed
  • A clean version you can confidently publish or send
  • A concise note with suggestions for further improvements in content, style, or tone

You can always reach out to josiah@proofread.co for clarification on any specific note or edit.

Josiah is 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. Josiah was very responsive and met all milestones as expected. I felt very confident in the work after it had been proofed by Josiah.

Make my reputation yours.

Backed by a satisfaction guarantee and a missed-deadline refund.

A decade ago, I noticed that writing from extremely intelligent, hardworking people was being undermined by preventable errors. Decades of expertise were being eroded by careless typos.

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 now, I’m the last line of defense for busy professionals.

I become an instant subject matter expert in your industry, then catch the typos and context-dependent errors that no tool can identify and most other humans miss.

You get real human judgment from a rigorously trained proofreader—and practically perfect documents.

You deserve nothing less than perfection.

So here’s my guarantee to you:

  • If you are not satisfied with the quality of my work after I return your document, I will proofread it again at no charge within 30 days.
  • If I miss your agreed-upon deadline, your project is free—no questions asked.

You’re protected, I’m accountable.

For People Who Require Perfection

Proofread.co is built for business professionals for whom mistakes are costly. If your work affects money, compliance, careers, contracts, or credibility, and you know you're too busy to catch every mistake yourself, my services are for you.

You need professional proofreading if you're a…

  • Finance or investment professional sending investor letters, private placement memos, or client-facing financial reports—where timeliness is crucial and error damages credibility.
  • Marketing or design agency with ongoing production cycles and no time or expertise to be the last set of eyes on every deliverable.
  • Technical writer or product team that needs a proofreader who will not change your language or ask you to explain terminology.
  • Nonprofit producing annual reports or printed donor materials with high reputational stakes.
  • HR or L&D/ID professional rolling out handbooks, compliance documents, or training programs where errors are a liability.

This probably isn't the right fit if you're a…

  • Student submitting a thesis or dissertation. I am happy to refer you to great academic editing services created for that purpose.
  • Blogger or content marketer publishing at volume where a conversational typo won't hurt you. Precision proofreading is overkill for content that lives and dies by the algorithm.
  • Fiction writer looking for a creative collaborator on your novel or short story collection. You deserve someone who specializes in that skillset.
  • Startup founder who does not see the value in proofreading and has a tiny budget for a long investor deck. AI Proofread might be the right tool for you.
  • Person with a 200-word document and a same-day deadline. The work is too small to do well, and you'd be overpaying.

Proofread.co vs. The Rest

Work with an on-demand expert without the markups, middlemen, or surprises.

With proofreading agencies, your document bounces from an intake coordinator to a project manager to a freelancer pool to a quality-control person.

That adds time and cost while sacrificing crucial context and consistency in decision-making. They also charge by the word, incentivizing rushing through their work.

My single hourly proofreading service is straightforward: focused, expert eyes on your exact draft for your deadline, with the flexibility to adjust for the depth of proofreading the document needs (without worrying about a per-word rate).

I am your proofreader from start to finish, and I offer a clear time and cost estimate up front so there’s no surprise quote creep.

I also keep all documents confidential, and will sign your NDA as necessary.

— Erica R., VP Strategy, Marketing & Advertising Firm

Your credibility is the whole point. That's why I offer a single service: expert-level, on-demand proofreading. Every document gets the same careful attention, and you'll receive a precise estimate based on its length and complexity before I begin.

But you don’t have to choose between fast and right. Your project will still get the same meticulous review.

Frequently Asked Questions

Proofreading is a final-pass review designed for documents where accuracy, consistency, and credibility matter. I do not:

  • Rewrite your work or change your voice
  • Make subjective style suggestions
  • Guess your intended meaning

If you are not satisfied with the quality of my work after I return your document, I will proofread it again at no charge within 30 days.

If I miss your agreed-upon deadline, your project is free—no questions asked.

I offer three turnaround tiers:

  • Standard — 2–3 business days ($68/hr)
  • Priority — under 24 hours ($82/hr)
  • Rush — same day ($94/hr)

Rush and priority slots are first-come, first-served and fill quickly around common deadline windows. Contact me with your deadline, and I’ll tell you immediately whether I can meet it.

Two things work together here: genuine curiosity and sheer repetition. I’ve always been a proofreader who wants to understand what I’m reading, not just fix commas. And after ten years of proofreading documents across virtually every industry, that curiosity has compounded into a broad base of working knowledge. I may not initially know your field the way you do, but I pick it up quickly, and that shows in the quality of proofreading.

Confidentiality is nonnegotiable. I routinely work with sensitive, pre-release, and internal materials, and every document is treated as confidential by default.

Files are uploaded and transmitted securely, reviewed privately, and never shared, repurposed, or used for any secondary purpose. If you need a mutual NDA, I’ll sign yours or provide my own.
