No, we do not use AI for rewriting suggestions, stylistic edits, or any substantive changes to your text. Our editing process is entirely human-driven to preserve your unique voice, intent, and message while ensuring the highest quality standards.

AI tools are limited in their ability to detect context, nuance, and tone. Our experienced editors bring a level of expertise and critical thinking that AI cannot replicate, ensuring your document meets professional and academic standards.

We take full responsibility for the changes we make to your manuscript, but we are not responsible for changes made after we return your document and before you submit your work to a journal.

If you edit your manuscript after we return it to you and submit your work to a journal without having the document proofread a second time, we will not be able to re-edit your manuscript for free.

We strongly recommend that you have a professional editor proofread any changes that you make to an edited manuscript before submitting it for publication.

We do not edit text solely to reduce AI scores, and we cannot guarantee that we can lower your AI score. AI checkers typically look for the patterns commonly found in AI-generated content, but sophisticated human writing or text edited by humans can share similar features, making any attempts to detect the true source of material difficult. AI checkers are extremely unreliable; they generate both false positives (incorrectly flagging human-written text as AI-written) and false negatives (failing to detect AI-written text) and therefore cannot be relied on. This makes attempts to lower the AI score difficult. What we can do is humanise your text so it sounds, to the human ear, as though it was written by a human.

While we do our best to accommodate any requests for specific editors, it may not always be possible if the order is for a 12-hour express turnaround. However, for orders with deadlines of 24 hours or more, we are almost always able to assign your preferred editor.

If you are not satisfied with the service you have received and can cite fair justifications, we will issue a partial or full refund or arrange for a re-edit.

We guarantee that we will significantly improve the language of your documents. Our performance is measured by your satisfaction; if you’re not entirely happy with our work, contact us and we’ll find a suitable resolution.

If your file is over 20,000 words, you may submit it to us via email (as an attachment), and we will provide a free sample of 500 words within 24 hours.

There’s no substitute for subject-matter expertise. With 300+ editing professionals, we have expert editors across the full spectrum of academic disciplines. This broad base of knowledge allows us to pair documents with editors who have relevant expertise.

The editing manager reviews each file before assigning it to the most suitable editor on our team. We will always select the editor whose experience and qualifications are the best match for the subject of the paper.

While we make every effort to ensure that your editor has experience in your discipline, we cannot always guarantee that the editor will be an expert in your sub-discipline. For example, if you submit a paper on molecular biology, we may select an editor with a background in the wider discipline of biology but not necessarily in the specific sub-discipline of molecular biology.

We’ll email you a secure download link to your edited document.

You’ll be able to download both ‘tracked’ and ‘clean’ versions of your file. The ‘tracked’ version shows the editor’s changes and comments, while the ‘clean’ version has all of our changes accepted and all tracking and comments removed.

We won’t send any physical or printed copies.

No, we don’t offer writing, paraphrasing or translation as part of our service. We focus on providing a premium-quality editing and proofreading service.

Absolutely! Simply note this on the order form and we will assign your new order to your preferred editor, subject to their availability.

If you’re unhappy with the editor’s work, please contact us and we’ll find a suitable resolution. This may take the form of a free re-review by a different editor, or a partial or full refund, depending on the circumstances.

Our Quality Guarantee means you can be confident that we’ll deliver high-quality work to you.

Our editors may use AI tools such as Microsoft’s Editor and Grammarly for basic spelling and grammar checks to ensure your document is free from typographical and grammatical errors. These tools are helpful for catching simple mistakes quickly and efficiently.

AI tools are a useful starting point for identifying basic issues, allowing our professional editors to focus on more complex elements of your document, such as clarity, coherence, and adherence to style guides. They are inherently limited, though, and can only be used by professional editors who understand when to accept or reject their suggestions.

Humanising text means refining its language, tone, and clarity while preserving the author’s original intent. Our editors enhance the readability of your work to ensure that your content feels natural and authentic. This means removing some of the tell-tale signs that AI was used to write content, including extreme wordiness, repetition, overreliance on certain sentence structures, incorrect register, monotony, and vagueness. We rely on our human expertise to determine whether a piece of text sounds human; we don’t use AI checkers to verify AI scores, as these programs are entirely unreliable and produce inconsistent, flawed results.

No, we don’t use AI checkers. These programs attempt to identify whether content was written by AI or a human, but their results are completely unreliable. AI checkers typically look for the patterns commonly found in AI-generated content, but sophisticated human writing or text edited by humans can share similar features, making any attempts to detect the true source of material difficult. They generate both false positives (incorrectly flagging human-written text as AI-written) and false negatives (failing to detect AI-written text) and therefore cannot be relied on. Instead, we rely solely on our expert human editors to ensure your content is polished, natural, and effective, without consulting automated tools for verification.

If you list your requirements in the order notes, we will check that your references are consistent with your preferred style guide. However, we don’t supply reference content or cross-check references with original sources.

Note that we don’t convert author-date styles to numeric styles, or vice versa; for assistance with this, please contact us for a bespoke quotation at [email protected].

Any files submitted to us will be kept in the strictest confidence.

Only members of the Cambridge Proofreading team will have access to your files. We do not share client files externally under any circumstances.

We will gladly sign non-disclosure agreements (NDAs) on request.

We are happy to sign NDAs on request. Please contact us for more information.

They also have years of editing experience and are members of leading industry bodies, such as the Council of Science Editors (CSE) and the Chartered Institute of Editing and Proofreading (CIEP).
