Bring the characters, the moment, and the change you want to explore. Build a fanfiction draft around the voices and relationships that made you care in the first place.
A missing conversation can be more interesting than another world-ending battle. A different decision can open an entirely new timeline. Use XPT as an AI fanfiction generator to explore those possibilities through a writing brief: who is involved, what they know, where the scene belongs, and which parts of canon should stay intact.
Start with a scene, an alternate-universe premise, or an outline for a longer fic. Give the conversation room to develop, then revise any line that sounds unlike the character you know. You decide what becomes part of your story.
Describe the fandom, characters, timeline, established facts, and any deliberate changes. Add the current relationship and scene problem.
Specify point of view, tense, tone, approximate length, and the emotional change you want. Ask for an outline first if the premise needs work.
Review dialogue, character knowledge, and canon details. Request a targeted rewrite, such as less exposition or a slower shift in trust, before continuing.
Name the fandom and continuity, then explain the relevant facts in your own words. A film adaptation, a game route, and a later book may give the same character different histories. State the point where your story begins and exclude spoilers or events that have not happened yet.
“Keep them in character” leaves too much open. Explain who avoids direct answers, who uses humor to deflect, and who shows care through practical actions. Include a short passage you wrote if you want the draft to follow your own rhythm.
For slow burn, ask for a small change in trust rather than an immediate confession. For a reunion, decide what remains unresolved. A scene becomes easier to revise when you know how the relationship should differ at the end.
Fill the quiet space between two established events. Give the scene a purpose, such as an apology that changes the next conversation, without rewriting everything that follows.
Write My Missing SceneMove the cast into a different setting while choosing which traits and relationships survive. Explain how the new circumstances affect their behavior instead of changing only the scenery.
Create My Alternate UniverseChange one decision and explore its consequences. Track who learns about the change, which alliances shift, and what the characters lose by taking the new path.
Explore a Different TimelineGive an OC a role, personal stake, and limitation. Ask for a scene in which they affect an existing conflict without automatically becoming the center of every character's attention.
Bring My OC into the StoryA useful fanfiction brief has two parts: facts the scene must respect and changes you deliberately want to make. For a missing moment, the second list may be empty. For an AU, it might replace the setting while preserving a rivalry, a protective habit, or an unresolved attraction.
| Story direction | Keep fixed | Decide before drafting |
|---|---|---|
| Missing scene | Timeline and what each character knows | What changes between the characters in this gap |
| Canon divergence | Events before the changed decision | Which consequence becomes the new problem |
| Alternate universe | Selected traits and relationship tensions | How the new setting changes their behavior |
| Crossover | The rules you choose from each world | How conflicting abilities or assumptions interact |
Draft a missing scene for [fandom and continuity], after [event]. Use [POV and tense]. The characters are [names and relevant traits]. Established facts: [facts]. Do not include events after [cutoff]. At the start, their relationship is [state]. By the end, [small change]. The immediate problem is [problem]. Keep these traits: [voice notes]. Write roughly [length]. Do not resolve [larger conflict] yet. If a canon fact is missing, ask me rather than inventing an answer.
Revise the speaker's tactic before adding a catchphrase. A guarded character might change the subject; an impatient one might demand a concrete answer. Ask XPT to preserve the scene objective while making those approaches distinct, and keep your own judgment about the character's voice.
If a line depends on a canon fact you did not supply, check it rather than building the next scene around it. Before sharing the finished fic, review the requirements of your intended community and any relevant permissions; generation does not establish publication rights.

Start with one unresolved moment. Set the boundaries, explore a draft, and keep shaping it until the characters feel recognizable to you.
