In keeping with ethical standards for editors, we are careful not to take control of the content away from the author – for example, all of our edits are tracked so that they can easily be accepted or rejected as you see fit. Moreover, we do not add significant novel material to a paper, as this would constitute (ghost) authorship rather than editing.
In addition, language editing focuses on making your text sound as though it is written by a native English speaker. Although our editors have subject expertise and may occasionally point out what they believe are content-related problems, they will not review content or take any responsibility for content.
