Frequently asked questions about professional proofreading

Do you have any doubts? Perhaps you can solve some of them by taking a look at questions that our customers often ask us.

I believe I have a strong command of the language I write in. Do I really need a professional proofreader?

If you’ve reached this page, you’re probably unsure—and if in doubt, the answer is usually yes. The increasing competition in thesis submissions, research publications, patent applications, etc., combined with the decline of editors in publishing houses and journals, has led to higher rejection rates. Authors are now responsible for delivering documents with the highest linguistic quality and terminological precision. If you have invested time and money in a project, ensuring it is impeccable reduces the risk of failure.

I like my writing style. Will proofreading change it into something I don’t identify with?

No. A professional proofreader at Ampersand will identify what makes your writing unique and preserve it as much as possible while ensuring clarity and accuracy. If you only need a light review, we will focus on correcting grammatical, spelling, punctuation, and typographical errors.

How is the cost of professional proofreading calculated?

Like with translations, we have a set price per word, but we need to assess the document first, as additional factors may influence the cost, such as the need for a more in-depth revision. If you send us your document, we will provide you with a quote within a few hours.

How do you guarantee the confidentiality and copyright of documents for proofreading?

All our proofreaders are bound by a confidentiality agreement with the company, and in turn, we sign a confidentiality agreement with the client. If clients require a different type of contract, we can adapt accordingly.

In which languages do you proofread?

We have proofreaders for Spanish and Catalan, and in some cases, we can also proofread English texts written by native speakers. Please feel free to request more information.
