+ + +
+
+ Hi, {{ nickname }}! This is a fan fiction downloader, which makes reading stories from various websites much easier. Please paste a URL of the first chapter in the box to start. Alternatively, see your personal list of previously downloaded fanfics. +
+ +
+ Ebook format   +
+ +
+ +
+ + + +

+ Few things to know, which will make your life substantially easier: +
    +
  1. Small post written by me — how to read fiction in Stanza or any other ebook reader.
    2. +
  2. Currently we support fanfiction.net, fictionpress.com, fanficauthors.net and ficwad.com
    3. +
  3. Paste a URL of the first chapter of the fanfic, not the index page
    4. +
  4. Fics with a single chapter are not supported (you can just copy and paste it)
    5. +
  5. Stories which are too long may not be downloaded correctly and application will report a time-out error — this is a limitation which is currently imposed by Google AppEngine on a long-running activities
    6. +
  6. FicWad support is somewhat flaky — if you feel it doesn't work for you, send all the details to me
    7. +
  7. You can download fanfics and store them for 'later' by just downloading them and visiting recent downloads section, but in future they will be deleted after 5 days to save the space
    8. +
  8. If Downloader simply opens a download file window rather than saves the fanfic and gives you a link, it means it is too large to save in the database and you need to download it straight away
    9. +
  9. If you think that something that should work in fact doesn't, drop me a mail to sigizmund@gmail.com
    10. +
+ Otherwise, just have fun, and if you want to say thank you — use the email above. +

+ Few things to know, which will make your life substantially easier: +
    +
  1. + First thing to know: I do not use your login and password. In fact, all I know about it is your ID – password + is being verified by Google and is absolutely, totally unknown to anyone but you. +
    2. +
  2. + Small post written by me + — how to read fiction in Stanza or any other ebook reader. +
    3. +
  3. + Currently we support fanfiction.net, fictionpress.com, ficwad.com, fictionalley.org, harrypotterfanfiction.com, potionsandsnitches.net, and twilighted.net. + (fanficauthors.net withdrawn as they offer native ePub functionality now.) +
    4. +
  4. + You can download fanfiction directly from your iPhone, Kindle or (possibly) other ebook reader. +
    5. +
  5. + Paste a URL of the first chapter of the fanfic, not the index page, except for fictionalley.org. +
    6. +
  6. + For fictionalley.org, you need to use the URL of the story's chapter list, such as + this. Or the story text URL for fictionalley.org + one-shots, such as this. +
    7. +
  7. + One-shots, fics with a single chapter, are now supported. +
    8. +
  8. + You can download fanfics and store them for 'later' by just downloading them and visiting recent + downloads section. +
    9. +
  9. + Downloaded stories are deleted after some time (which should give you enough of time to download it and will keep + Google happy about the app not going over the storage limit). +
    10. +
  10. + If Downloader simply opens a download file window rather than saves the fanfic and gives you a link, it means it is + too large to save in the database and you need to download it straight away. +
    11. +
  11. + If you see some funny characters in downloaded Plain Text file, make sure you choose text file encoding UTF-8 and + not something else. +
    12. +
  12. + If you think that something that should work in fact doesn't, drop me a mail + to sigizmund@gmail.com, or, even better, write an email to + our Google Group. I also encourage you to join it so + you will find out about latest updates and fixes as soon as possible +
