For fan fiction writers
Your fandom, with the canon kept.
Write the continuation you always wanted. Lunafic was a professional writing tool before it turned into roleplay, so your fic is saved as chapters you can edit line by line. Characters carry their real personalities, and your fic stays private unless you share it.
The direct answer
Lunafic is where fan fiction characters actually stay in character, for forty chapters and more.
Every character you play with carries a world bible. The AI reads it before every reply, so the banter in chapter 2 still sounds like the same person in chapter 30. Your story saves as real chapters you can reread and continue any night.
It is a story space first. If you only want quick chats with no story, a chat app will feel simpler.
Real fan worlds, ready to enter
Pick a world. Play your night in it.
These are real fan worlds published in the catalog. Press Play, choose your hero, and your own story opens with every character ready. Everything you write in it is yours.
Canon that holds
The character you love is the character you get.
Personality, background, and what they would never say live in the character's world bible. The AI reads it every reply, so the tsundere stays prickly and the villain stays dangerous. When your story changes them, the change sticks.
Dual-language dialogue
Japanese lines, English right under them.
Anime characters speak Japanese with the romaji and the translation under every line. The story stays in English. You hear them exactly as they are without needing to be fluent.
Private by default
Private by default
Your story is yours. We never train AI on your writing. Other players never see it unless you publish it yourself. You can also export your chapters anytime, in every world.
What you get
What makes Lunafic different
For fan fiction, your private story keeps its chapters like a book, and every line stays editable.
Scene pictures
The person who builds a world prepares pictures for its big moments. When that moment happens in your story, the picture shows up right in the reply.
Narration
Many AI roleplay apps end a line by jumping ahead, telling you a detail will matter later. Lunafic narration stays in the moment with your character, so what happens next is still yours to decide.
Long-term memory
Chapter forty still knows what happened in chapter four. You never manage memory by hand.
MC Mode
You write your character. The AI plays everyone else and stops when it is your turn, so it never writes your words, thoughts, or actions.
Editor
Your story looks like a normal roleplay, but every line can be changed. When the AI gets a name wrong, tap it and fix the word instead of paying for a retry.
Dual language
Characters can speak their own language, like Japanese, with the translation right under each line, so they sound the way they should.

Questions fan writers ask
Is my fan fiction private?
Yes, private by default. Other players never see your story, and that stays true when you play inside a world someone else published. If you publish a world of your own, other people can play it, and every story played in it stays with the person who played it. Zero stories are used for AI training, and you can export the chapters you write in every world. Sharing is always an explicit choice you make.
Do I need to build the characters myself?
No. Press Play on a published world and every character comes with it, ready to play. You choose your hero, a role the author made or your own character. You can also build characters from scratch in a Private world of your own. However you start, the characters carry their world bible into every scene. Starting takes one click either way.
What fandoms are here?
The catalog grows from real published worlds, so it reflects what writers actually build. Anime, live-action shows, games, and original worlds all exist side by side. If your fandom is missing, you can build it tonight, keep it private, or publish it so the next fan of your series finds a home. The door is open whichever way you build.
The continuation is yours to write.
Play a world or build your own tonight. Your fic stays private until you say otherwise.
Free to start. Zero stories used for AI training.
