<h2 class="bb_tag" >One engine. Infinite stories. Your rules.</h2> 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: <ul class="bb_ul"><li>Death — Cold. Inevitable. Every choice has a cost, and the bill always comes due.</li><li>Prophet — The world whispers of what's to come. Every scene drips with foreshadowing.</li><li>Gambler — Luck, risk, and unexpected twists. Nothing is guaranteed.</li><li>Mentor — Patient. Guiding. The world teaches you its rules, if you're willing to learn.</li><li>Confidant — Intimate. Character-driven. Every NPC has a heartbeat.</li></ul> Built for Roleplayers <ul class="bb_ul"><li>Import your own character cards (PNG format supported)</li><li>Companion mode with relationship tracking — guardian, rival, confidant, or something unspoken</li><li>Inventory, quest log, and active party tracking</li><li>Three difficulty levels — from Relaxed to Brutal (not recommended without extensive preparations)</li><li>Progressive world-building — lore entries unlock as the story unfolds</li></ul> Play free. No subscription. No hidden fees. cost — roughly $0.14 per hour of play. 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. Welcome to Story Engine.
