Plot Builder

The Plot Builder is an optional system that generates a high-level narrative arc for your story before the AI writes your next turn. Think of it as a chapter plan — a 6–7 sentence outline of what should happen next, written specifically for your game’s current state.

What it does

Without Plot Builder, the AI responds to each turn in isolation — it sees your recent history and a few memories, and improvises the next beat of the story. This works well for short to medium games but can cause narrative drift in longer games: the story circles the same scene, loses stakes, or meanders without building toward anything.

Plot Builder solves this by giving the AI a target to write toward. Before generating your story turn, a separate step creates a narrative arc like:

“You discover the merchant’s ledger contains names of nobles connected to the disappearances. Following the trail leads to an abandoned estate. Inside, you find evidence of a forbidden ritual. As you piece together the conspiracy, someone discovers you snooping. You must escape with the evidence — the chase ends in a rooftop confrontation where the truth finally comes to light.”

The AI then writes your turn with this arc in mind — not following it literally, but using it as a directional guide.

When it activates

Plot Builder generates a new arc once per chapter. After creating a plot, that arc persists and guides the AI for multiple turns until the story naturally reaches a conclusion. Then a fresh arc is generated for the next chapter.

📝 Note: Generating a new arc costs 1 extra credit on top of your turn’s normal cost. If you don’t have enough credits, the current turn proceeds without generating a new plan, using whatever arc is currently active.

What it uses

The Plot Builder pulls from everything relevant to your current game state:

Input	Source
World setting	Your world’s lore and genre
Current theme	Your selected Writing Module (or genre if none set)
Relevant NPCs	Characters contextually relevant to the current turn
Player character	Full character details including personality
Important memories	Top retrieved memories from your Memory Book
Important lore	Top retrieved entries from your Lore Book
Story so far	Your recent history window

The result is a plot arc that feels specific to your game — not a generic fantasy plot, but one that references your actual characters, history, and themes.

Writing in second person

The Plot Builder always writes in second person (“you discover…”, “you must escape…”) to match Isekaigen’s story narration style. Each arc is designed to have a clear ending rather than a cliffhanger, so every chapter feels complete.

How to enable it

Open your game settings (⚙️ icon in the game toolbar)
Go to the Writing tab
Toggle Plot Builder on
Save settings

Plot Builder works in both Story Mode and RPG Mode.

Combining Plot Builder with Writing Modules

When you have a module selected, the Plot Builder uses that module’s theme to shape each arc:

Devil module → arcs lean toward moral dilemmas and dark twists
Cupid module → arcs build toward emotional revelations and romantic encounters
Sherlock module → arcs structure events as mysteries with clues leading to a reveal
Phantom module → arcs emphasize atmosphere, dread, and hidden revelations

If no module is set, the Plot Builder defaults to your world’s genre as the theme.

When to use Plot Builder

Enable it when:

Your game is 30+ turns in and the story is losing direction
You want the story to have a clear shape and build toward something
You’re playing in a complex world and want the AI to weave your NPCs together meaningfully

You might skip it when:

You’re playing a very short session and don’t need long-term structure
You want to fully control the story’s direction yourself
You’re very low on credits and want to minimize cost per turn

💡 Tip: Even an imperfect plot arc almost always pushes the story forward. A mediocre arc is nearly always better than no arc for long games.
