Are you wasting time proofreading your own documents
—and still seeing errors slip through?

You've re-read your work a dozen times. You're 90% sure it's clean. But after spending hours with your own words, you can't see your own typos, inconsistencies, or mistakes. Other solutions are futile:

  • Your coworker's "quick check" lacks context and a trained eye. They can't catch the mistakes that cost you credibility.
  • Spellcheck and ChatGPT lack human nuance—marking stylistic choices as errors while letting subtle, complex errors slip through.
  • A cheap freelancer will "fix" your voice until it sounds sterile.
Proofreading your own work doesn't make it better. It makes you worse.
Stop letting typos kill your credibility.
Start hitting "Send" with confidence.
A tiny typo can erase a whole page of trust.

Readers notice mistakes faster than they notice your expertise. Small errors indicate small attention to detail: One glaring error in your document, and your reputation takes a hit.

It's time to gain the confidence that comes from having a proofreader at your fingertips. My fresh, professional eyes can catch errors before anyone sees them.

You get to regain your time. Make your deadlines. And communicate clearly with your audience.

7-year track record with zero client-reported errors

Over the past decade, I've watched even the most intelligent, educated business leaders make errors that disrupt, distract, and detract from their communication.

So I have dedicated my career to proofreading complex, high-stakes documents—ensuring they carry a lucid message and flawless content.

I've carefully honed my talent for finding mistakes that are invisible to others, as well as my talent for rapidly learning new industries. That combination is rare, and it's why clients return year after year.

I've used those skills to perfect thousands of investor letters, offering memoranda, white papers, and board presentations for clients like Rockefeller PA, TEDx, and the CDC—and now I'm ready to do the same for you.

Before You Hire

Smart questions to ask before hiring…

Most of my clients are strong writers, which is precisely why proofreading matters. When you are close to your work, your brain reads what you meant, not what it says. I bring a trained, external set of eyes to catch the errors and inconsistencies you can't see, before your audience does.

Critical documents deserve more than algorithms. Automated tools catch most surface-level issues (e.g., grammar, spelling, punctuation) while missing context, meaning, and subjective credibility-impacting details.

I provide the human judgment, rigor, and confidentiality that an AI or spellcheck tool cannot.

See Services for details—or if you're still keen to use AI, check out AI Assist.

No. I preserve your tone and voice while highlighting only errors. You decide which changes to keep.

Yes. I specialize in complex documents where accuracy, clarity, structure, and consistency matter: technical reports, regulated materials, executive communications, and those with reputational or legal risk attached.

No one. I routinely work with sensitive, pre-release, and internal materials, and it is all reviewed privately and treated as confidential by default. Unlike many AI tools or agencies, I will sign an NDA.

I can generally handle last-minute, high-pressure submissions, but rush slots are limited and frequently become unavailable.

I will communicate up front about whether I can deliver on your timeline. Contact me—or, if you're really pressed for time, sign up for ai.proofread.co.
