I am also a student,
I have the same need like yours, so I thought to request a plugin which can solve that, nobody seemed interested then, and even now…
My idea was Obsidian App can can itself serve content over internet, yes it is possible if electron has that API which Chrome has which allow us to serve content from local storage to the Internet.
This way we can access our notes in LAN, provided PC is switched on😅.
Another good thing will be when if Obsidian is available as a lightweight webapp too, so that we can connect GoogleDrive or simply upload vault folder etc to read notes in any browser any device…
