I think you should ask yourself, if you just want text, or if you'd like to have embedded images as well. In general it sounds, as if you are looking for something to publish notes. This could be simple text files on a webserver, or Markdown/Org-Mode files on a webserver, or Markdown/Org-Mode files converted to HTML on a webserver, or a tool like HedgeDoc: https://hedgedoc.org/
