Genre Blender Idea Tool
Two genres
What each genre promises
Fantasy
Elements
- — a map that redraws itself
- — a debt owed to something older than the kingdom
- — a gate that opens only for the willing
Conventions
- — a journey out of the known world
- — a rule of magic with a price
- — a confrontation with what the hero refuses to become
Science fiction
Elements
- — a ship running past its rated life
- — a system that has started answering back
- — a colony whose records do not match its population
Conventions
- — a technology that changes what is possible
- — a consequence measured in decades
- — a question about who counts as a person
The collision
Collision
A fantasy story opens on a map that redraws itself; a science fiction story opens on a ship running past its rated life. They are the same object, and the fantasy element that refuses to fit is why nobody agrees what it is.
Deadline
The protagonist must resolve a system that has started answering back before a debt owed to something older than the kingdom comes due, and the fantasy element that refuses to fit is the only thing that buys time.
Inversion
The science fiction conventions hold — a consequence measured in decades — until a gate that opens only for the willing arrives and forces the fantasy question: a rule of magic with a price.
Cost
Solving a map that redraws itself the fantasy way would satisfy a colony whose records do not match its population, but breaches a question about who counts as a person. The compromise satisfies no one.
Frame
Tell a fantasy story inside a science fiction one: a debt owed to something older than the kingdom is the frame, a ship running past its rated life is the case, and the fantasy element that refuses to fit is what the frame was built to hide.

Checks
No required element; naming one — an object, a line, a place — keeps the collision specific instead of generic.
Scope and limits
Each scaffold pairs one element from each genre and keeps a convention from both sides, so the blend stays legible to a reader of either shelf. Names, plots and characters come from you.
A blend is not a promise of a market: read the two conventions lists and decide which one the story will break, because a mash-up that honours neither set reads as neither genre.
The genre blender idea tool collides two genres' stock elements and reader conventions into five premise scaffolds, keeping one thing from each side that a reader of either shelf would still recognise.
What is Genre Blender Idea Tool?
The genre blender takes two genres and shows what each one brings to a mash-up. Every genre carries elements — the objects, pressures and situations its readers expect to encounter — and conventions, the kinds of scene the genre is built from. A blend only works when both sets stay recognisable, so the tool puts the two lists side by side before it generates anything, and the writer can see what a reader of each shelf will expect to survive the merge.
The five scaffolds are fixed templates, not random combinations: collision, deadline, inversion, cost and frame. Fixing them matters because they are different kinds of story rather than different flavours of the same one. A collision asks what happens when the two genres' opening objects turn out to be the same thing. A deadline imports the pressure of one genre into the timeline of the other. An inversion makes one genre's convention the force that breaks the other's. A cost makes the solution satisfy one set of expectations at the expense of the other. A frame tells one genre's story inside the other's, with the required element as the thing the frame was built to hide.
The required element is the tool's one optional input and its most useful. Left empty, each scaffold falls back to a phrase about the element that refuses to fit. Name something concrete — a ledger, a shared recording, a door that opens inward — and the element appears in all five scaffolds, including the cost scaffold where it becomes the compromise that satisfies no one. That single input is usually the difference between a premise and a prompt.
Two habits make the blend easier to test. First, write the two opening images the collision paragraph describes — one from each genre's element list — and read them back to back; if they cannot plausibly be the same object or the same room, the collision needs a different pair of elements. Second, name the blend after what it does rather than after the two shelves: a mystery with a western's obligations is a different promise from a western with a mystery's alibi, and the name is the first thing a reader uses to decide whether the friction is for them.
The checks name the three ways a blend fails before it starts. The same genre twice is not a blend, because there is no second set of expectations to collide. A missing required element leaves the collision generic. And when the two genres share their first convention, the tool says so, because the blend then needs a different point of friction than the obvious one.
What the tool cannot do is promise a market. A mash-up is read by people who already like at least one of the two genres, and the blend has to decide which convention it will break; a story that honours neither set reads as neither genre, and one that honours both without friction reads as a shelf label rather than a premise. The two conventions lists are there so that decision can be made deliberately, in the same pass as the idea.
Names, plots and characters are yours. The genre blender provides the collision and keeps the two expectation sets visible while you work on the premise; the scaffolds are starting positions for an outline, not outlines. Take the one that makes you argue with it — often the cost or the frame where the two genres genuinely disagree.
How to use Genre Blender Idea Tool
- Pick two different genres from the list.
- Name one required element — an object, a line or a place — that must survive the merge.
- Read the two elements and conventions lists and note where they disagree.
- Choose the scaffold that makes the disagreement do work, and draft the premise from it.
- Clear the checks by naming the element and confirming the two genres differ.
When to use Genre Blender Idea Tool vs related tools
Use the genre blender idea tool when a story needs a fresh engine rather than a fresh coat of paint: a premise that feels familiar, a shelf that has been read out, or a project that has stalled because its genre expectations are too comfortably met. Once a scaffold is chosen, the Plot Structure Planner maps the premise's want, conflict and stakes onto beats, and the Ending Generator tests which verdicts that collision can pay off. If the genre pair is the real problem, start from the Story Idea Generator and blend once a single-genre premise exists.
