The hardest part of documents within a business is not producing documents but rather creating a useful library. Google Docs is a place where great documents go to die.
Notion’s success (for example) is more about it making it possible to create a useable library of documents than it is about being an editor with neat widgets.
I don’t know if Hermes is going to be particularly successful given it’s competing with things like Notion, but in principle, a library for Google Docs is a great and valuable project for teams using Google Docs.
