故事引擎：随心所叙

One engine. Infinite stories. Your rules.

Story Engine is not a game with a pre-written plot. It is a narrative engine that revolves around you — every choice, every word,

every direction takes the story somewhere completely different.

Pick a world. Pick a companion. Pick a GM persona. Then the story begins.

Walk into a tavern. Start a war. Fall in love. Betray a kingdom. Open a bakery in a quiet village. No dialogue wheels. No invisible

walls. You describe what you do — the AI unfolds what happens next.

Five GM Personas

The GM is the soul of every tabletop campaign. Choose the one that fits your mood:

• Death — Cold. Inevitable. Every choice has a cost, and the bill always comes due.

• Prophet — The world whispers of what's to come. Every scene drips with foreshadowing.

• Gambler — Luck, risk, and unexpected twists. Nothing is guaranteed.

• Mentor — Patient. Guiding. The world teaches you its rules, if you're willing to learn.

• Confidant — Intimate. Character-driven. Every NPC has a heartbeat.

Built for Roleplayers

• Import your own character cards (PNG format supported)

• Companion mode with relationship tracking — guardian, rival, confidant, or something unspoken

• Inventory, quest log, and active party tracking

• Three difficulty levels — from Relaxed to Brutal (not recommended without extensive preparations)

• Progressive world-building — lore entries unlock as the story unfolds

Bring your own key. Play free.

No subscription. No hidden fees. Connect your own API key and the engine runs at cost — roughly $0.14 per hour of play. If you'd rather not deal with API setup, use the relay service via one-time Steam DLC.

You can also connect your own image generation API for character portraits and scene illustrations.

Made by a non-programmer. With Claude Code.

The developer had never written a line of code before this project. The entire engine was built through conversations with AI. If that sounds wrong — it probably is.
