Lunafic

Inspiration

Lunafic started from my hobby of roleplaying with AI (raw LLMs), which I have done for years. I always imagined myself entering the world of fiction, but I found many problems while doing it.

The first prototype of Lunafic was bad and generic. Then we took a detour to create a professional writing tool for novelists and screenwriters that, in the end, no one used. I decided to return to the initial idea, using the same engine and what I learned.

What it does

Lunafic is a platform for AI roleplay characters you build stories with over long, continuous memories. It is an opinionated AI roleplay experience featuring long-term memory, chapter progression with a beautiful editor instead of endless generic chats, and a solution to the long-standing problem of multi-character consistency.

Key Facts:

• Professional narrative: Unlike ordinary chat models, Lunafic runs on the Lunafic V2 professional writing engine adapted into entertainment roleplay. Narrative depth, Characters that can fight back, Cinematic dialogue pacing, Persistent continuity, It waits for your turn
• Layered long-term memory: instead of treating memory as same persistent, we separate the layer of memory which you don’t need to think much when using it.
• Is it a fiction editor or chat roleplay? Both. No need to choose.
• MC Mode is the default: You play and chat as your character, the AI never writes your character's dialogue, thoughts, or actions.
• World Bible: Every character comes with a world bible that details how they talk, how they act, and what secrets they keep hidden
• Beyond endless chatting: Ever felt stuck confused what to do anymore chatting? Lunafic is a story you think it as a free story of yourself
• Dual-language dialogue: We provide dual-language dialogue with Romanized and English translations right underneath each line, so you can hear their exact speech styles in your head without needing to be fluent.
• Solving characters showing up out of nowhere with “In scene”. We solved the long-standing problem of multi-character roleplay writing.
• Instant-character chat: You think Lunafic can't become chat? Click the character you want to talk with, then you're ready to set.
• Thoughtful design: Lunafic is built beyond a bare chat box. We take care of your immersion from avatar dialogues, SFX typography, managing many characters in one scene, an editor-first approach where you can extend character and story freely rather than filling long forms, floating action pills, preventing accidental enter submissions while typing, and an expanded canvas to read

How I built it

I'm using React for the frontend web, Expo for mobile apps, Hono for Backend, and several other libraries that too many to be mentioned. The design is customized by myself while the coding worked by several combination of frontier AI agents.

Challenges I ran into

The memory system and the UX were the hardest part that took 2 months to fully stable. I learned a lot from user behaviour.

Accomplishments that I'm proud of

Just releasing it already accomplishment for me, moreover getting paid users that trust the product even though it had unstable moment. I'm building this all myself.

What's next for Lunafic

Fundraising, we are on advanced discussion with VC and Angel Investor
