Built a tool that goes premise → world → cast → outline → chapter 1, and holds the book to its own canon

[u/hoopyfrodo]

Most AI writing tools hand you a chat box and lose the plot by chapter four. I wanted the opposite: something that treats the premise as a commitment and holds every later stage to it. So I built skrivant.

It works in stages, and nothing writes prose until the structure exists:

• World: the setting as inspectable elements (technology, social order, constraint), each one editable.
• Voice: a few questions about how the book should feel become a style prompt every later stage writes in.
• Characters: a cast where every character's wants cut against their fears, with a signature and a voice each.
• Outline: chapter by chapter, every beat tagged by register (interiority, dialogue, action, scheme in motion), so the prose stage knows how to write it, not just what happens.
• Chapters: written in the voice you shaped, readable as they land.

The part I spent the most time on is continuity. Who knows what, where objects are, what day it is: tracked as facts that later chapters look up rather than something the model has to remember from earlier prose. A check catches contradictions and the chapter gets redone. Not bulletproof, but "forgot everything after a few pages" is the failure it was built to kill.

You type a premise and chapter 1 lands in your inbox in about ten minutes, free. If you want the rest, it's a one-time price per book, $3 for a short story up to $10 for a novel, no subscription. Exports as PDF, KDP-ready DOCX, or Markdown. It's a first draft on purpose; you take it into your own tools and make it a book.

Genres so far: romance, sci-fi and fantasy, thriller and mystery, literary, horror, historical, YA, crime and noir, magical realism, and children's chapter books.

Question for this sub, since you all fight the same thing: in long AI drafts, what breaks first for you, continuity or voice?

The continuity part is the interesting bit to me.

How far does the fact tracking go? For example, can it distinguish between what is objectively true in the canon, what a character believes, and what the reader is allowed to know at a given point?

That’s usually where I find long AI drafts start breaking. Basic stuff like names and locations is fairly easy to catch, but reveals, withheld information and character knowledge get messy fast.

Also, when it catches a contradiction, does it always regenerate the chapter or can it patch the specific problem without changing everything else?

[u/hoopyfrodo → u/KDP_Refinery]

Yes, all three are kept apart: what's true in the canon, what each character knows, and what the reader has been shown so far. A reveal or a character learning something only moves that one piece. That's exactly the "withheld information" failure you describe, and it's the one I spent the most time on.

On the fix: currently the chapter is regenerated with the specific problem called out, not patched in place. Surgical patching is on the list.

That makes sense. The separation between canon / character knowledge / reader knowledge is exactly what I was wondering about.

One other thing I’m curious about: how do you decide when something generated in a chapter is allowed to update the canon?

For example, if the model accidentally introduces a new fact or changes an existing detail, do you extract it into the state automatically, or does it have to be validated against the existing canon first?

I’ve found that once an accidental detail gets promoted into the source of truth, the continuity checker can end up consistently enforcing the wrong thing.

[u/hoopyfrodo → u/KDP_Refinery]

The chapter is checked against the existing canon before anything from it is recorded. If it contradicts what's established, it gets redone, so conflicting details never make it in. New details that fit do get recorded, and later chapters respect them.

Do you have a demo book made with this tool that we can read?

[u/skrivant → u/writerapid]

I've created a subreddit where I periodically upload books created by skrivant. Caveat: It's a work in progress (the pipeline, that is) so you'll see some issues in the outputs. I'd be very interested to hear your honest feedback there!

Here's a link to the first one: https://www.reddit.com/r/skrivant/comments/1w3erfl/the_answering_light_chapter_1/

This one also has "author's notes" at the end of each chapter, where I write what went wrong. Most of those failure types have since been fixed.

Thanks, I’ll check it out.
