Yes. You can upload LaTeX documents to our system for proofreading and editing. We then extract the number of words that aren’t markup and charge you on that basis (i.e., you only pay for the content of your document, not the formatting). See below an example LaTeX document being uploaded.
We charge a 20% premium on our regular prices for LaTeX files. When we are finished, we return an edited Track Changes version of your document content as an MS Word (DOCX) file along with your edited LaTeX (TEX) files in their original format. For detailed information on our LaTeX proofreading and editing services, see our LaTeX proofreading and editing page.
