Startup Idea: Content Calendar and Research App for Course Creation

Startup idea to develop a software that streamlines content creation for online courses, by integrating a content calendar and resourceful article generation feature for each topic, for ease in content planning and writing.

Content Calendar and Research App

I'm creating an online course about a fitness topic. The hardest part about creating the course is the writing involved. There are various ways writers and marketers create content for the blog, website, or books. I would like a solution that was part Content Calendar and part researcher. What I mean is, if there was a way for software to HELP me research a topic and provide a list of relevant articles so that I don't have to do this manually each day. This way, the research part would be taken care of (saving me tons of time or $$ to outsource) and I could happily start writing right away. Integrating the research with a content calendar would be really convenient and allow me to manage writing tasks in one easy interface.

Maybe something like this already exists; is so I've never heard of it. I've used different writing apps and most are just word processors. I want something that will help with research and help to plan and schedule the content I'm creating which will cut down a lot of steps and save me tons of time.
