Which engine compiles my document?

XeLaTeX from TeX Live, with fontspec and polyglossia, which is what Arabic and Unicode text need.

Are my documents stored?

The source stays in your browser. It is sent to the compiler to build the PDF, which is deleted from the server after an hour.

Do I need an account?

No. The editor is free and works without an account.

Can I use images or several files?

Yes. A project can hold up to 40 files: .tex chapters, .sty and .cls files, and up to 20 PNG or JPG pictures (3 MB each, 6 MB in all). Use \input or \include for chapters and \includegraphics for pictures.
