Novarrium for Fanfiction Writers

Write in the World You Love, Without Breaking Its Canon

Lock the canon you are keeping, change the parts your story changes, and let the drafting stay inside those lines.

3 free chapters. No credit card required.

Readers notice when a character is out of character, when an eye color is wrong, when a rule of the world quietly stops applying. Novarrium lets you decide exactly which canon you are keeping and which your story changes, then holds every chapter to that.

The consistency problem

Canon Slips

A chatbot forgets a detail every reader knows by heart, and the comments section finds it first.

AUs Get Muddled

Your story diverges from canon at a specific moment. Generic tools blend the two versions together.

Long Fics Drift

Forty chapters in, small details from chapter three no longer match.

What Novarrium does about it

Canon You Choose

Lock the character details and world rules your story keeps. Every chapter is checked against them.

Divergence at a Chapter

Record where your story changes canon. Chapters before that point keep the original truth, chapters after it follow yours.

Continue What You Started

Import the chapters you have already written. Novarrium extracts the facts and picks up where you left off.

Build it once. Keep it true.

Straight answers

Do I have to enter all of canon myself?

You enter what your story depends on, or import your existing chapters and review what Novarrium extracts. Locked facts are the ones it enforces.

Can I publish what I write?

Your writing is yours to export. Where you publish fanfiction is between you and that platform and its rules.

Already have a manuscript?
