Side by side
A read-it-later app for articles, PDFs, ebooks, newsletters, RSS and video transcripts, with highlights that sync to Readwise and note apps.
A browser extension for Chrome, Firefox and others that saves a complete web page, including images and styles, into a single HTML file, with a CLI version too.
Paid subscription only, and it is most valuable if you also use Readwise review.
Pages with heavy dynamic content can save imperfectly, and the AGPL applies if you build on the code.
