Phase 1
Obsession before product
Arbiyanto Wijaya spent over a year writing almost every day with AI, mostly fan stories built on anime, games, and light novels. That daily habit is where Lunafic comes from.
About Lunafic
A private space to play inside the story
Lunafic began with Arbi writing almost every day with AI, playing inside stories from anime and games. That was the initial idea: you play one character, the AI plays everyone else.
The product took a detour and became a writing tool for professional writers. It taught us something on the way: the fun part was never the writing tools. It was playing inside a story.
V3 combines what we built in both versions. You roleplay inside worlds you already know, on top of a professional writing engine, and nobody reads your story unless you publish it. It exists for fun.

From V1 to V3
The story so far
From playing inside stories, to a writing tool for professionals, and back to playing again.
Phase 2
A wild idea, a real partner
Arbi and Naufal Badalsyafiq brainstormed multiple ventures together. Lunafic stood out as the most ambitious and the most alive.
Phase 3
V1The first version
Turn-based character roleplay. You step into a character, the AI plays the rest of the cast. The idea was right, but the experience was too thin: a plain text box, weak memory, no real editor.
Phase 4
V2The writing tool detour
Talks with professional teams showed the same writing pain at a bigger scale, so Lunafic became a writing tool for professional writers. That phase built the engine: a true editor, deep character profiles, chapters, branching, export. Professionals did not stay, but the engine is what V3 runs on today.
Phase 5
V3NowBack to the initial idea
V3 combines V1 and V2: playing inside a story, on top of the professional writing engine. You play your character, the AI plays everyone else in their own voice and language. Your story saves as chapters, every line is a save point, and it stays private until you publish it.
The V3 philosophy
What we believe
A private space
Your story is yours. Nobody at Lunafic reads what you write, and zero stories are used for AI training. Nothing goes public unless you publish it.
An otaku space
Built by otaku, for otaku. Anime and games first, but not only Japanese: Korean manhwa, K-pop, western series, and local pop culture all belong here. Whatever world you love, you can step into it.
Local pop culture, understood
We are the same team behind Arxist.id, a creator community in Indonesia. Fandom is different in every country, and we build with that understanding, from local payment methods to the way fans talk about the worlds they love.
Pick a world and start playing
A growing library of worlds you can step into. You play your character, the AI plays everyone else.
