Laser focus on the detail when you're word-blind.

When you're working closely on a document, it's virtually impossible to see the types of errors that a proofreader would pick up. You're looking big picture; I'm zoning in on the detail.


Marketing and communications teams often plan to proofread internally, but the pressure of deadlines and other demands means the depth of proofreading isn't possible. The errors might be small, but they can be costly.


That’s where I can help.


When we work together, I'll act as another member of your team – responsive and reliable – at the end of an email whenever you need me.


My sole focus is on absorbing myself in your copy and eliminating all those errors that you might not see, but your readers will.


You see, I don't just read, cover to cover – that comes way down the list.


I'm looking at:

  • consistency (did you use a hyphen on page 4 but not on page 50);
  • has your business name been used correctly;
  • does your document even follow your own house style;
  • why does this link take you to the wrong page;
  • whether the contents page has been updated;
  • has any AI copy crept in that changes the tone from the rest of the publication;
  • what's going on with the formatting in section 4; that picture doesn't match the caption... etc).


That's before I read the file as your reader would.


I spot the important stuff that spell-checkers, digital grammar tools and AI, like Copilot, miss.


But as an experienced proofreader, I'm not here to show off.


I only mark up what you need to be marked up. I'm always thinking about you (and your designer) having to work through the amends (on a hefty, complex report, this could be hundreds) – so my work will be precise, clear and understandable. Designers can implement the changes quickly and accurately, and I'm always here to check any queries.


I'm ready to provide the safety net that you need with your written word.


How the process works.

1. Send your document.

Email your file or brief.

2. Approve the quote.

I'll confirm the cost and schedule.

3. Receive your file.

Returned with tracked changes or clear proofreading markups.

Human proofreading for AI-generated business content.

AI tools can speed up content creation and produce what looks like a 'grammatically perfect' document, but they often introduce awkward phrasing, inconsistent tone, subtle grammar errors and formatting issues.


Fixing this yourself can take the time that you've saved in the first place.


I will ensure your final content reads naturally, clearly and professionally.




Proofreading for school, college and university publications.

Schools, colleges and universities produce a wide range of printed publications each year, from prospectuses and yearbooks to admissions guides and marketing materials.


These publications need to be accurate and inviting – accessible to students and parents alike. I provide careful, precision proofreading to ensure your most important communications are clear, correct and ready for print:

  • School and college prospectuses
  • Yearbooks and leavers’ books
  • Admissions guides
  • Course brochures
  • University marketing publications



"The consistency and attention to detail throughout were much appreciated. I look forward to working with Kelly again and would highly recommend her proofreading services."
– Sibford School, Oxfordshire
