The canon engine for serialized fiction.
Import your series, lock your canon, and enforce it across hundreds of chapters -- so your readers never catch what you missed.
Import up to 10 chapters free -- no account needed
Import your series
Drop in your existing chapters. AI extracts every character, rule, and plot thread into a Story Bible automatically.
Write your next chapter
Write it yourself or let AI draft it. Either way, your canon is injected and enforced.
9 checks, every chapter
Character traits, world rules, dead characters, POV -- all verified before you publish.
You can track canon in a spreadsheet for 20 chapters. By chapter 50, something slips. By chapter 100, your readers are keeping better notes than you are.
