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.
Targets, formatting and checks follow the format you choose. On the right is what the studio's output looks like for each one.
Write a long book with a story bible the AI actually reads. POV and tense drift are flagged with their location, and the notes read like an editor's.
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.
Chatbots were built for conversation, and a story is not a conversation. We fixed the three things that break first in long-form writing.
Around chapter twenty your protagonist's eye color changes and a dead character speaks again. You paste your notes in every session.
Reads the relevant characters, places and threads from your Bible on every generation, and flags prose that contradicts them.
Ask for “a bit longer” five times and you still land around 900 words.
Every chapter has a target. The AI fills the scene inside it, with word or character counts the way your platform counts them.
Converting one scene into a screenplay spends half the prompt explaining the format.
The same manuscript, as a properly formatted script with scene numbers and (V.O.)/(O.S.) cues, scene by scene, Bible intact.
Different stories need different tools. Pick the guide closest to yours. We list where it does not fit, too.
Canon drifts after chapter 50 and episodes stall short of target.
An AI that reads your bible, writes to the target and checks the hook.
Read the guideInsert one scene and every number shifts; character voices drift.
Auto scene numbers, dialogue from the character sheet, HWP and FDX export.
Read the guideThe panel script changes shape every week and your artist reformats it.
A fixed panel, shot, action and dialogue table, and a bible that lasts past episode 100.
Read the guideChapter one gets rewritten ten times and chapter four never exists.
Synopsis and plot drafts, then notes ranked the way an editor would.
Read the guidePOV wobbles in part two and ages drift during revision.
POV and tense checks, bible cross-checks, continuations in your voice.
Read the guideA character who never smiles in canon keeps smiling in AI prose.
Writing inside canon cards, with out-of-character lines flagged before you accept.
Read the guideKeep characters, places, world rules and open threads as cards. Whether you continue, rewrite or expand, the AI first picks the cards relevant to the current scene and reads them. As the Bible grows, your prompts don't.
Set a target and a cut point for every chapter, and count words or characters the way your platform does. The AI fills the scene inside the target and checks whether the ending pulls readers into the next chapter.

“You know you don't come back once you cross.”
Write TV and film scripts without fighting formatting. Scene numbers are assigned automatically, and action, character cues, dialogue and parentheticals are real styles, not spaces. Move a novel into script form scene by scene.
12 EXT. BLACK RIVER LANDING - NIGHT
Fog. JIAN stands with the oar, not moving. Across the water, one light in the reeds.
OLD MAN (O.S.)
You know you don't come back once you cross.
JIAN
(touching the knife at her hip)
I know. That's why I'm going.
13 EXT. THE RIVER - NIGHT
Structure, pacing, point-of-view drift and Bible conflicts, ranked by priority. No padding with praise. Each note is anchored to the manuscript, and you decide what to change.
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.
She gazed upon the river with a profound sadness, contemplating the weight of her destiny.
Jian looked at the river. Not for long.
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.
Jian offers the ferryman a ring instead of a coin.
Dialogue in fog. The ferryman never asks her name.
Jian looks back. The boat is already gone.
Start from a blank page or paste what you've already written. Characters and places are found in the text and suggested as cards.
Continue, rewrite, expand description, tighten dialogue. Every action reads the Bible and the previous chapter first.
Check structure and continuity, then take the whole project as DOCX, TXT, Fountain or HWP-compatible files. The manuscript is always yours.

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.
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.
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.
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.
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.
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.
Free credits on signup. Start without a card, and take your manuscript with you anytime.
