“Authoring tools are software and services that people use to produce Web pages and Web content. “

An explanation in the article “A Review On Authoring Tools” written by Khademi, M., et al is clear too.

“… a program that helps you write using hypertext or multimedia applications and enable you to create a final application merely by linking together objects, such as a paragraph of text, an illustration, or a song….”

There are some sources listing useful authoring tools below. I won’t call them authoring tools, but put them under the LCMS.
