My current tentative workflow:
1. Use Hypothes.is to annotate and PDF's (works on most websites).
2. Import them in readwise.io
3. Sync them through Readwise plugin in Obsidian
4. Zotero for academic articles. PDF annotation on iPad through Zotfile, and export notes as Markdown.
Has anyone found a better way without involving Readwise for active learning - through Annotation+ Bookmarking and without paying the monthly charges from Readwise?
P.S. I use raindrop.io for bookmarking+ IFTTT to send it other online channels.
