Voice
Characters who sound like themselves.
Write voice notes into each character’s card: how they talk, what they would never say, who they call by a nickname. Those notes sit in front of the storyteller whenever that character is in play.
AI fanfiction writer Stay true to canon, right up until you don’t.
Keep the canon details that matter on lore cards, pin the moment your AU breaks away, and play the scenes that follow with a storyteller that brings each card back when its name comes up. Everything stays private unless you choose to publish.

The short answer
Can you write fanfiction with AI?
Yes. On LoreWeaver you roleplay fanfiction with an AI storyteller inside a private world: canon characters, places, and events go on lore cards that join the scene when their names or tags come up, and a pinned card can hold the moment your AU leaves canon. Memories and a running recap carry earlier chapters forward, and any story exports as a Markdown file. Fan works are welcome for personal, non-commercial use, and it is free to start.

Canon on cards
Canon the storyteller can look up mid-scene.
Each lore card holds one piece of canon: a character’s voice, a city, the battle everything turns on. A card joins a reply when its title or one of its tags appears in the last 12 messages or in your new move, so nicknames and titles make good tags.
Pin the few cards that must never slip, like the moment your AU leaves canon, and they go in first on every reply. Switch a card off when a scene wanders somewhere it doesn’t belong.
Kestrel Dawe
Importance
Description
Courier of the Glass Court. Answers a question with a question, never says goodbye, and calls the queen “madam” only when she is furious. Hums off-key when she is frightened, and would sooner climb than ask for help.

Alternate universes
Six kinds of AU, and how to build each one.
| AU | What changes | How to set it up |
|---|---|---|
| Canon divergence | One event goes another way, and everything after follows from it. | Pin a card that names the moment and what happened instead. |
| Fix-it | A character canon lost is alive, or a wrong is put right. | Rewrite their card for where they stand now, and say so in the premise. |
| Modern AU | The same people, in a different time and place. | Keep the character cards, write new location cards, and set the era in the premise. |
| Role swap | Heroes and villains trade sides, jobs, or fates. | Change each card’s role and leave the voice notes alone. |
| Missing scene | A moment canon skipped or kept offstage. | Write it as one of the world’s openings, so a story can start right there. |
| Self-insert or OC | You join the cast as yourself or a character of your own. | Save a persona with a name, a look, and a history, and bring it into any AU. |
Staying in voice
What keeps a long fic consistent.
See how memory and recaps workStyle
The source’s rhythm, in your rules.
Style rules set point of view, tense, and pacing for the whole world, whether the books read like a court drama or a ship’s log.
Plan
A story plan it reads every reply.
Session notes hold up to 500 tokens of direction that the storyteller reads on every reply: where this session is going, who is angry with whom, and what must stay secret.
Memory
Earlier scenes, kept and editable.
Memories are written every few replies, and a running recap sums up the story. Both are yours to edit, so a detail the story got wrong can be fixed by hand.
Takes
Try the scene both ways.
Branch from any message to play the confession two ways, or ask for a new version of the latest reply and keep whichever reads true.
Export
Take the words with you.
Export any story as a Markdown file, each turn labeled by speaker, ready to shape into chapters.
Fan works here
Fan fiction is welcome, with a little care.
Welcome
- Worlds inspired by the books, games, shows, and films you love, made for personal and non-commercial creative use.
- Original characters, self-inserts, and AUs, private unless you publish them.
- Lore you have already built: SillyTavern World Info, character cards, NovelAI lorebooks, and AI Dungeon story cards import into any world.
Keep in mind
- Don’t claim official affiliation with the original work, and be mindful of trademarks.
- Publish only what you have the right to share. A world made from someone else’s character card asks you to confirm the creator’s permission before it can go to the Hub.
- Never republish another creator’s world as your own.
- Copyright concerns can be reported, and the team looks into each one.

Questions
Before you play the first scene.
01Is fanfiction allowed on LoreWeaver?
Yes. The community guidelines welcome worlds inspired by existing books, games, shows, and films for personal, non-commercial use. Don’t claim official affiliation with the original, be mindful of trademarks, and only publish what you have the right to share.
02Does the AI already know my fandom?
It may know a famous story in broad strokes, but its memory of any one canon is uneven, and it can mix up details. Put what your fic depends on into lore cards and the premise, and the storyteller gets those details whenever the story mentions them.
03How do I keep characters in character?
Three habits help most. Give every character a card with notes on speech and temper, list their nicknames and titles as tags so the card comes in whenever they are mentioned, and set point of view and tense in the style rules. If the story still gets a detail wrong, edit the memory that holds it.
04Can I write a self-insert or play my own OC?
Yes. Save a persona with a name, a portrait, and up to 5,000 characters of description, then choose it when you start a story. The world calls you by that name wherever it writes {{user}}.
05Can I share or publish my fanfiction?
Your worlds and stories stay private unless you publish. Publishing puts a world on the Hub, public or unlisted, with its lore cards and openings, never the stories you wrote in it. Keep fan worlds non-commercial, don’t claim affiliation with the original, and publish only what you have the right to share.
06Will my fanfiction be used to train AI?
No. LoreWeaver’s terms say it does not use your private content to train or fine-tune AI models, and any use beyond aggregated, de-identified metrics would need your explicit opt-in.
07Can I export my fic?
Yes. Export any story from its menu as a Markdown file, with each turn labeled by speaker, ready to edit into chapters.
08Is it free?
Yes. The free plan has unlimited replies from the free storyteller plus 25 premium replies a day. Paid plans, from $7.99 a month, add more premium replies, more memories per story, and more of the story in view at once.
