The Ferryman of the Black River · Ch. 12

Jian did not put the oar in the water. The river was black again tonight, and across it, in the reeds, a single light was burning.

“You know you don't come back once you cross.” The old man's voice sat lower than the current. Jian touched the silver knife at her hip. The engraving caught on her fingertip.

A crow perched on three waves. The same mark she had seen on the old man's sleeve in chapter eleven.

Watch it work on a sample novel

You write. It remembers everything.

Chapter 4 of the sample novel Ferryman of the Black River. It recalls the last chapter, catches misspelled names, tracks every plot thread, finds plot holes, separates character voices, plans the next chapter, and exports a KDP-ready book.

Karen stopped at the edge of the reeds. Lyria followed behind.

The reeds swayed at night though there was no wind. A few lamps drifted between the stalks.

"From here we walk," Karon said. "Boats can't cross reeds. Follow the lamps but don't touch them, and never go where the lamps go out."

"You said there's no boat back. Then how does my brother get out?"

Karen's voice was low.

"Find him first. Then think."

Lyra touched the knife. The sheath was cold. They went into the reeds.

Chapter 7 · The Ferryman's Daughter

Jian did not put the oar in the water. The river was black again tonight, and across it, in the reeds, a single lantern had been lit. Three nights running now. Someone lit it at the same hour, waited long enough to be sure no boat was coming, and put it out.

“You'll cross tonight,” the old man said. It was not a question. Jian touched the silver knife at her hip and felt the pattern under her thumb: a crow on three waves, the same mark she had seen inside his sleeve.

Why not a general chatbot

If you've tried to write a novel in a chatbot, you already know.

Chatbots were built for conversation, and a story is not a conversation. We fixed the three things that break first in long-form writing.

01

Memory of your world

General chatbot

Around chapter twenty your protagonist's eye color changes and a dead character speaks again. You paste your notes in every session.

SparkLore

Reads the relevant characters, places and threads from your Bible on every generation, and flags prose that contradicts them.

02

Chapter length

General chatbot

Ask for “a bit longer” five times and you still land around 900 words.

SparkLore

Every chapter has a target. The AI fills the scene inside it, with word or character counts the way your platform counts them.

03

Prose to script

General chatbot

Converting one scene into a screenplay spends half the prompt explaining the format.

SparkLore

The same manuscript, as a properly formatted script with scene numbers and (V.O.)/(O.S.) cues, scene by scene, Bible intact.

Tell the assistant

Character cards appear, chapter one gets written, and every step can be undone

No buttons to hunt for. Talk to the assistant in the corner: it reads the bible, creates cards for characters that do not exist yet, and drafts to your chapter target. Every action carries an undo.

A few thousand words are enough to build a voice profile: sentence length, dialogue ratio, description density, tense and distance. Continuations stay inside that profile, and tell-tale AI phrasing is filtered before it reaches your page.

Adaptation

Break a manuscript into scenes and carry it into a TV script, a feature screenplay or a webtoon storyboard. Pitch documents and episode grids come from the same Story Bible. You reorder scenes and fix lines on cards; the AI writes in that order.

How it works

Three steps, no setup

  1. 01

    Build a Bible or import a manuscript

    Start from a blank page or paste what you've already written. Characters and places are found in the text and suggested as cards.

  2. 02

    Write chapter by chapter, scene by scene

    Continue, rewrite, expand description, tighten dialogue. Every action reads the Bible and the previous chapter first.

  3. 03

    Get feedback, then export

    Check structure and continuity, then take the whole project as DOCX, TXT, Fountain or HWP-compatible files. The manuscript is always yours.

FAQ

Before you start

  • Do you train AI on my manuscript?

    No. Your manuscript, Story Bible and prompts are never used to train any model. Only the text needed for a generation request is sent to the AI provider, and this is stated in our Terms and Privacy Policy.

  • What is a credit and how far does it go?

    One credit is roughly 100 words of AI output. Filling a 2,500-word chapter entirely with AI would cost about 25 credits; mixing continuations with your own writing costs far less. If a generation fails, the credits are refunded.

  • What can I do for free?

    Signing up unlocks free credits and one project. The Story Bible, chapter mode, screenplay mode and export are all available on the free plan. You can also try the free tool pages a few times a day without an account.

  • Which formats can I export?

    Prose exports to DOCX and TXT; scripts export to Fountain, FDX (Final Draft) and an HWP-compatible document. Export never costs credits, and you can take the whole project at once at any time.

  • What about publishers' and platforms' AI policies?

    They differ. Some contests prohibit generative AI; some platforms have no rule yet. Always check the platform or contest guidelines before submitting. SparkLore is a tool for drafting, revising and keeping continuity; the copyright and responsibility for the finished work remain with the author.

  • Can I bring a manuscript I've already started?

    Yes. Paste text or upload a DOCX or TXT file and it is split into chapters. Characters and places found in the text are suggested as Bible cards, and your voice profile is built from that manuscript.

The next chapter gets written today.
