Hacker News Reader

My choice (manual): Markdown clipper

I guess there are dozens of alternative extensions available out there …

This fork:

With extension available for Firefox, Google Chrome, Microsoft Edge and Safari.

Wallabag + Obsidian + Wallabag Browser Ext. It's a manual trigger but its great.

Omnivore. Saves a copy using web archive.

Wouldn’t that describe Pocket, Readwise Reader, Matter, or another one of those many apps?

Edit: read too fast. Didn’t notice the automatic and systematic aspects.

Pocket saves the address; I don't think they save the content.

Just checked it, they also save the content.
