AI Visual Novel Creator
Generate a fully playable visual novel game from a single sentence — character sprites, scene backgrounds, branching story, LLM real-time dialogue, all AI-generated. No coding required.
Generate Your Game in One Sentence
Enter an IP name or original concept. AI builds the world, generates character sprites, writes branching dialogue — <span class="ml-highlight">a playable game in minutes</span>. No coding, free to start.
What the Game Looks Like
Generated visual novels run directly in the browser — branching dialogue, meter systems, character sprites, scene transitions, all rendered in real-time. Dialogue is improvised by LLM, every playthrough is unique.
Five Steps to a Playable Game
Enter One Sentence
Enter an IP name or original concept. "Bungo Stray Dogs", "Demon Slayer", or "a time traveler investigating serial disappearances in Victorian London".
AI Builds the World
Auto-generates a complete world: characters (with backstories), locations, events, factions, ability systems. Each card has original descriptions and cover art.
AI Creates the Game
Selects a storyline, writes game logic (meters, intents, milestones), generates all art assets and BGM.
Publish & Play
Auto-builds a project, publishes as a playable game. Players play directly in the browser, no download needed.
Fork & Remix
Any public world can be forked — inherit all characters and scenes, rewrite what you want, publish your own version.
Auto-Generated Assets
After entering one sentence, AI auto-generates all art assets — no drawing, no searching, ready to use out of the box. Character sprites are auto background-removed transparent PNGs, scene backgrounds are 16:9 HD, style is consistent.
Character Sprites Auto-Generated
Each character auto-generates a neutral expression sprite, transparent PNG, directly overlayable on scenes. GPT Image 2 Gemini 3.1
Scene Backgrounds Auto-Generated
Each location auto-generates a 16:9 HD background, consistent style, directly usable for game scene transitions. AI matches lighting, atmosphere, and composition based on location descriptions.
Infinite LLM Storytelling
The game engine runs a real-time LLM, improvising narrative prose in each character's voice. No fixed script — every choice is continued into a unique story by AI, theoretically infinitely extendable. Every playthrough is one of a kind.
Game Mechanics for Infinite Expansion
Each game has three built-in systems driving LLM infinite storytelling:
- Meter System — Trust, Heat, Resolve, Compassion and other customizable axes. LLM reads current values to determine NPC attitudes and story direction.
- Intent System — Each scene defines available intents (investigate, fight, persuade, sneak, etc.), LLM generates corresponding narrative based on player's chosen intent.
- Milestone Gating — Key plot points set as milestones, meters must reach thresholds to advance. LLM generates rich side narratives before gates.
Together, LLM has enough structural constraints to maintain story coherence, and enough freedom to improvise — theoretically infinitely extendable. DeepSeek V3 Kimi K3
