hfy2epub is web-tool to turn post series from reddit.com/r/HFY into EPUB files for easy offline consumption with a reader or text-to-speech.
All work to identify the posts, fetch them and turn them into an EPUB are performed in the browser.
Note: Be fair to the authors. Do not distribute the resulting EPUB files unless you own the rights to all the material and/or the author gave you permission. In general respect the author's wishes and do not use this tool if the author is not ok with it. When in doubt ask the author.
