Zotero
Zotero collects the articles, books and web pages you use for research, keeps your notes and PDFs together, and writes citations and bibliographies in Word or LibreOffice. It has a free plan with limited cloud storage.
How hard it is to start using it. Easy: install it like a normal app, or use it in your browser. Advanced: you run it on your own server, use the command line, or it is a tool for developers.
