Co-create Stories

Live the story you imagine

Create the character you want and live your own adventure.

Co-create Stories is a single-player AI text RPG where every line and action is entered in your own words. The AI game master responds to what you try and continues the story.

Bribe a guard to enter through the back gate. Fight, flee, persuade, betray, or try something no fixed menu could predict. Every adventure unfolds differently.

DICE-DRIVEN OUTCOMES

Actions such as picking a lock or bluffing a guard are resolved with 1d100 checks based on your character's strengths and weaknesses. Success and failure both move the story forward.

A FULL RPG SYSTEM

Grow your character through turn-based battles, skills, equipment, shops, and crafting. Build around eight attributes, cooperate with companions, and keep the items created during your adventures.

OPTIONAL CHARACTER VOICES

An optional in-game download can play the GM, NPC, and companion dialogue as speech. Voice playback is available in Japanese only and requires a GPU with at least 12 GB VRAM plus 12 GB of available storage. The full game remains playable with this feature disabled.

STREAM PARTICIPATION

During YouTube live streams, viewers can submit free-form actions or vote on the next choice.

LANGUAGES

Japanese, English, Simplified Chinese, Traditional Chinese, and Korean. You can switch the text language at any time in the game.

WHAT YOU NEED TO PLAY

Story generation requires a stable internet connection and an API key from a supported external AI provider. The in-game recommended setup uses Google Gemini for Story AI and OpenAI GPT-5.6 Luna for Support AI. API charges are not included in the game price, and provider pricing or free-tier conditions may change.

ABOUT AI OUTPUT

Stories and conversations are generated by AI, so each playthrough is different. The output may occasionally include unusual wording or unexpected developments.
