Obligatory mention of emacs+org. I've tried everything and anything, and it seems to be a common pattern that people with a streak of perfectionism go through a long journey of dissatisfaction with tools, a journey which seems to settle in emacs+org-mode for many.

I really, really like the combination of Joplin, the Joplin extension and Pocket. The export tools offered by the Joplin extension combine well with the readability processing/formatting that Pocket applies. You can save a markdown-version, save URLs only, the complete HTML of a page, or just some text you've selected.

I have some boilerplate HTML that adds spoilers and a couple other bits to make my rendered notes look nicer and help me study, along with a couple of templates for embedding YouTube videos, Spotify and Github Gists. Most of this is on the Joplin forums, I encourage you to take a look if that sounds appealing to you.

There's a mobile app, and Joplin exposes a REST API the extension uses - I have a few hacky scripts to help me use Joplin as a CMS for a website (still a messy WIP, might show this & the templates to HN soon).

I'm exploring Emacs & Org-mode right now since it pairs well with Haskell, which I'm learning during this whole lockdown thing - even with all my Joplin-based stuff I can see why people accept the trade-offs and buy into it completely. Now might be a good time to try emacs+org out, for those lucky ones just riding lockdown out at home.
