Why is AxiomStory the editorial choice?
We make AxiomStory, and we built it for books where details must stay straight across many chapters. It reads your chapters, builds a wiki of your characters and places, and flags lines that disagree. It needs an internet connection, so it isn't for writing fully offline.
Is there a free option?
Yes. AxiomStory is free to start without a card, and you can upload a manuscript to try the wiki.
