Lots of Document with Author "John Smith" or "Word Document" as Title? CTX brings this problem to the front and gives you quick fixes, like one click to "make me the Author" or to quickly set an accurate title.
You have so many content tools but they all hide document metadata in servers where it can only be used in that platform. CTX makes it easy to put metadata into the "Dublin Core" properties Author, Title, and Keywords, which are passed with the document between publishing systems, and not lost when you "print to pdf".
You have to read content to identify keywords, but it takes time to do this. CTX reads for you and highlights your terms in documents while listing them for your convenience. Just click what you like to add terms to the document's "keywords" property, or browse the document for highlighting to see what sections are the most intersting for you.
