Web Widget for Notes


I am looking for a 3rd party note-taking site to use as a web widget on a dashboard. I was previously using a Rich Text widget on the app and calling it the "Bulletin" but this is clunky. In order to add/ edit text on this bulletin, we have to "edit" the dashboard and click save. I want it to be edited easily. There has to be a million options for this so please let me know!!

Thanks Community!
