hijacking for a bit of shameless self promotion: if you're an obsidian user, I recently built a plugin that simplifies web pages, parses out metadata, and saves them to obsidian as markdown files: https://github.com/inhumantsar/slurp

arXiv comes through a bit ugly atm but it's high on my to-do list. I'm leveraging the library that Firefox uses for reader mode, so most sites come through quite well. A lot of my work right now is expanding their metadata support and fixing parser issues.
