Blogbook is an app in development that one can use to make PDF and EPUB files by exporting from WordPress, Micro.blog, or Ghost blog to a single Markdown file. Filter by categories, authors, tags, and dates–then open in Marked 3 for PDF, EPUB, and more. I can create a physical book from an export of my micro.blog to Day One, but that takes all posts in a date range while what I really wanted to do was only publish in book format essays.
