Innwords is a fan-made site dedicated to The Wandering Inn web serial by Pirateaba.
The goal from the start was to parse all individual words of the complete series, put them in a database and then see what it could be used for. There is now also a more generic search that isn't word based, and a try to map words to different categories such as character names and aliases, classes, skills etc.
One of the interesting effects of this is that because all information is mapped to a specific word, sentence, paragraph and chapter, it's possible to make it safe from most spoilers by using the Include chapters filter in the sidebar. This means that it's possible to search the story, and look at the different statistics, even for users that are not up to date.
To enable more advanced functionality, like for example alias to character mappings, data is also taken from the wonderful The Wandering Inn Wiki.
