For original creators

Let fans build the world-lines your story hasn't reached yet

"What happened next?" "What if that character were the lead?" Let your fans make those sequels and alternate routes themselves, only within the limits you set. Every work they make keeps a link back to yours.

We're looking for our first 5-10 participating creators. Applying is free.

Who this is for

  • Web-novel and light-novel writers
  • Indie game and visual-novel circles
  • Creators with an original VTuber or characters
  • Webtoon creators

  • Owners of small original IPs

Available today

These features are live on AI BunCho now.

  • Choose what to allow, per work

    For each published work, choose Off, Structure/characters/setting, or Including dialogue. Change or stop it at any time. For novels, the text itself is never handed over - only chapter and scene summaries.

  • How fans can remix

    Allowed works show "Remix this work". Fans choose Change the protagonist, Change only the heroine, Change the ending, Change the genre or Make a sequel, and start their own work.

  • A link back to the original (lineage)

    Every remix keeps a link to the original, and your work's page lists "Works born from this one" - so readers of fan works find their way back to you.

  • Some works are excluded

    Remix permission cannot be turned on for limited-visibility works and some other visibility settings.

Coming soon

Coming soon

We're building these with feedback from our first creators and will update this page when they ship.

  • Fine-grained remix licenses Coming soon

    Allow or deny side stories, IF routes, new characters, AI-written text, AI images, monetization and remixes of remixes, one by one.

  • Human-centric mode Coming soon

    A mode where the creator requires fans to write and draw themselves, with AI used only for checks such as typos and continuity.

  • No AI training on your work Coming soon

    We're preparing to make "your works are not used to train AI models" the default and state it in our terms.

  • Templates for fans Coming soon

    Ready-made formats for IF and rescue routes, reader-insert stories and fan games.

  • Sharing back with creators Coming soon

    We're exploring ways to share part of fan works' revenue with the original creator.

FAQ

Can people use my work without permission?

Only published works you have allowed can be remixed. You can turn permission off at any time, after which no new remixes can be started.

Who owns what fans make?

Fan works are published as the fan's own work, with a link to yours. Your rights in your work stay with you. Fine-grained licenses and revenue handling are coming soon and will be announced here and in our terms.

Can I apply if my work isn't on AI BunCho yet?

Yes. Creators who publish elsewhere are welcome.

Does it cost anything?
