When people think of "an edge tool for academic writing", LaTeX may be the first software that comes to their mind. Indeed, the mathematical formulas written in and academic articles typeset by LaTeX are very beautiful. But an ordinary user who has used LaTeX a few times could hardly like it, because its syntax is a markup language that is essentially designed for the machine, not for human to read - just as the HTML source code is designed for the browser, not directly for Internet surfers.

As we all know, PDF document format has been very widely used now. And, this document format can only be opened or edited with a specialized editor. Even so, PDF files are not that easy to edit. This case, you can give Infix PDF Editor a try. It is a powerful, fast, flexible, comprehensive and easy-to-use PDF editing software. AppNee regards it as an unofficial successor of the classic but discontinued Foxit Advanced PDF Editor (I suspect they both use the same source code).
