Worlds to step into
AI roleplay that writes a real story
A world that you can inhabit as a character. You play your character, the AI plays everyone else in their own voice and language, and every scene becomes a chapter of your story.
Imagine
You're in the middle of a scene, in the world of your waifu.
Kirino, Ruri, and you, in the same place.
You write a line as your character. Then you direct the scene.
"Is that Kirino?"
Kirino demands to know why Ruri is here. Ruri answers in her own language. You try to explain. It gets worse.
Ruri heard the footsteps before the door opened. Heels. Fast. Kirino.
"Nande kono ko ga iru no?"
Why is SHE here?
Kirino stepped inside. Her heel caught the edge of the rug. She kicked it flat.
"Kuso. Ren, anta ga yonda no?"
Crap. You called her?
You avoided it. You weren't the one who called Ruri.
"Anta, atashi to kono hen na yatsu o onaji hi ni yobu nante. Saitei."
You invite me and this weirdo on the same day. The worst.
show, not tell. no "she was hurt"
show, not tell. no "she was hurt"
The word landed. Ruri's fingers tightened on the teacup. Just slightly. Just enough.
"Yoku iu wa... eroge-zuki no anata ni."
Bold words... from someone who plays eroge.
action beat grounds the line
action beat grounds the line
She set the teacup down. The porcelain met the table without a sound.
"Dorobouneko."
Thieving cat.
"Nani!? Dare ga!?"
What!? Who is!?
Kirino's hand closed around your sleeve. Ruri's hands stayed on the table, perfectly still. You looked at one, then the other.
It knows them because it reads your notes. Every character detail, every relationship, every rule you wrote.
You directed the scene. It wrote the words.

Why the voices hold
The AI reads this before every reply
Maomao
Every character comes with a world bible that details how they talk, how they act, and what secrets they keep hidden. The AI reads all of this before every reply, so characters stay consistent for forty chapters without losing their personality.
Speech Style
Guarded ReferenceDeadpan, formal, detached. Then the subject turns to poison and the voice goes breathy and dreamy. Someone about to drink something fatal? Every formality drops and she barks orders.
How the AI makes her sound.
Personality
Read-onlyRaised in the red-light district. She counts relationships as transactions, avoids palace politics, and is entirely immune to Jinshi’s charm. Underneath: a sense of justice she cannot switch off.
How the AI makes her act.
Speech Examples
Guarded Reference"Fugu no doku... ano piripiri shita shibire ga ii n da. Aa, tabetai..." · "Keishou wa irimasen." · "Shao... tte, ikinari chan-zuke desu ka."
The actual lines the AI builds from.
Guarded panels shape the character’s voice in your story without showing the author’s raw text. The craft stays with the person who built it.
Meet someone tonight
You direct. The AI roleplays in character
You give the direction for the scene, and the AI writes the dialogue and action while respecting what your character actually knows.
If your character only knows someone by a nickname from chapter two, the AI will not magically spoil their real identity until someone reveals it in the story.
- ✓You can imagine yourself inside the world
- ✓Beautiful avatar dialogues for your characters alongside the dialogues
- ✓Knowledge leak detection
Step into the role. You write your character's dialogue and actions, while the AI only plays the other characters in the story.
Pairin, Meimei, Joka line up. You look at the three. You point to Joka. "Honestly her face is my type, but she seems like she'll kill me if I pick her." Then you turn to Pairin. "Tell me about yourself. What do you like? What do you do outside work? What do you wish?"
Before Joka could formulate a response, the ever-eager Pairin stepped forward.
"Fufu! Heika, watashi wa Pairin to moushimasu wa!"
Fufu! Your Majesty, my name is Pairin!
Pairin leaned in slightly, a breathy, seductive lilt in her voice.
The AI never writes your character. It stops when you must act.
Story memory
Chapter 40 still knows what happened in chapter 4
Your secret is safe with me. However long this story runs.
"Sou, kouhyou shinai."
Right. We never make it public.
still true in every chapter between
Chapter 40
Someone asks about the rumor. She does not even glance your way.
"Naisho!"
Secret!
The wink is for you alone.
the same secret, chapter 4 to chapter 40. she never told a soul
In a chat, chapter 4 scrolled out of the window long ago. Here it rides every reply, with the world’s own notes beside it. There is no memory feature to unlock and no plan tier for it.
"Uso wa tobikiri no ai nan da yo?"
"A lie is the utmost love, you know?"
Ai Hoshino, quoted from her world bible
Capture the trueJapanesenuance
Our battle-tested characters are ready to import, but what truly brings them to life is the nuance. Otaku culture thrives on Japanese voice acting, yet reading Kanji is hard, and English localization often loses the original soul.
We provide dual-language dialogue with Romanized Japanese and English translations right underneath each line, so you can hear their exact speech styles in your head without needing to be fluent.
- ✓Hear the exact voice acting cadence in your mind
- ✓No more awkward or stripped-down English localization
- ✓Perfect for Anime, Manga, and Light Novel fanfiction
"Wait, why are you here?" Souma asks Roroa.
"Souma-han toko ni totsugi ni kitan ya."
I've come to marry into your family, Souma-han.
She speaks in a heavy Kansai dialect, her sharp merchant mind hidden behind a boisterous, playful smile.
You spoke in English. Roroa answers in her own voice, with her own cadence. The AI stays in character.
Find any chapter, character, or lore instantly.
Instead of opening twenty different notes or scrolling through old chapters, you can search across all your characters, world rules, and past scenes in one place.
Is it a fiction editor or chat roleplay?
Both. Lunafic invented a way for you to retain both ways without choosing. How? All your roleplay lives inside the editor. You will get very powerful tools while keeping immersive roleplay. You can type / anywhere to insert dialogue bubbles, scene breaks.
The core difference
A chat that ends, or a story you keep
Ever felt stuck confused what to do anymore chatting? Lunafic is a story, you think it as a free story of yourself, you decide to be the character, tell your ideals, philosophy, and world view to the characters.
Chat roleplay
Session · last message weeks ago
"Anata-tachi, watashi no purin o katte ni tabeta wa ne?"
Fun for a night. Then the chat went quiet, and the story had nowhere to go.

Chapter 6 · The West Tower
The West Tower, past midnight. Two small trespassers, one empty pudding jar, and the rumor of a witch to answer to.
the pudding incident, exactly as her world bible tells it

"Anata-tachi, watashi no purin o katte ni tabeta wa ne?"
You two ate my pudding without asking, didn't you?
She does not raise her voice. She never does. Two small apologies follow, and she accepts both before either of them can start crying.
"Sonna koto shinai wa. Dakara anshin shite."
I would never. So rest easy.
Then the promise that turns one night into a next chapter.
and tomorrow happens. saturday, the tower opens its door to nekoya

Come back tomorrow at noon. I will show you a witch's magic.
Tomorrow is Saturday. The day her tower opens a door to another world, and pudding comes after the main course.

Straight answers
What is Lunafic?
Lunafic is an AI roleplay platform where you play as your own character and the AI plays everyone else in their own speech styles and native languages. Characters only know what has been revealed to them, and every scene saves into real chapters that you can edit, branch, or keep as a saved story. It is completely free to start and stays private by default.
Can I write fan fiction with my favorite characters?
Yes. The library carries published worlds built on franchises people love, each with a cast that stays in character because the AI reads their profiles before every reply. When you write, the world becomes your own private story where nobody sees it unless you publish. Worlds set their own maturity rating, and your writing is never used to train AI.
Is my story private?
Private is the default. Zero stories are used for AI training, nobody at Lunafic reads what you write, and nothing becomes public unless you publish it yourself. Every writing feature works without ever publishing a single chapter, and you can copy your text to your clipboard or download your chapters anytime.
Is it free to start?
Yes, with no credit card required. The free plan includes full editor features and monthly AI credits to explore stories, meet characters, and create chapters. Paid plans exist for players who want more credits, deeper models, and higher limits. You can start completely free tonight, and upgrade only when your story asks for it.
How is it different from Character.ai?
Most chat apps lock you into a single scrolling chat room with one bot and no way to organize chapters. On Lunafic, you step into a whole world with a full cast, world rules, and an opening scene. Everything you write lands in an editor where you can branch paths, characters speak their native languages with English translations underneath, and a World Bible keeps their personalities consistent.
Can I stop the AI from writing my character?
On Lunafic, MC Mode is turned on by default, so the AI is strictly blocked from writing your dialogue, your feelings, or your actions. You control your character, while the AI only plays the other characters in their own speech styles and native languages without you having to constantly remind it.
How does Lunafic remember a long story?
There is no memory feature to unlock and no plan tier for it. Before every reply, the AI reads your chapters so far, plus a structured world bible with each character’s profile, relationships, and what they personally know. The engine picks what the scene needs instead of replaying an ever-growing chat log. Chapter forty still knows what happened in chapter four, and search finds every line you have written.
Step into a world that writes back.
Pick a world, play your character, and let the AI bring everyone else to life. Your roleplay becomes a story you can come back to.
