Summon Worlds is a fantasy worldbuilding, story-planning, and roleplaying app for writers, worldbuilders, Dungeon Masters, and tabletop RPG players. Create characters, locations, items, spells, relationships, and lore in one connected universe. Then step inside your world with Adventure Mode and experience interactive stories shaped by the characters, history, and rules you created. Free to start, with no ads ever. BUILD A CONNECTED FANTASY WORLD Create detailed characters, locations, weapons, items, spells, and lore. Link everything together so your world stays organized and important details are never lost. Build character profiles with backstories, classes, alignments, stats, personality traits, and original AI-generated artwork. CREATE MEANINGFUL CHARACTER RELATIONSHIPS Define friendships, rivalries, romances, family bonds, alliances, and other connections between your characters. These relationships become part of your world’s lore and can influence the stories and adventures that unfold. STEP INSIDE WITH ADVENTURE MODE Turn your world into an interactive, AI-guided roleplaying adventure. Play as one of your characters while the game master narrates the story, responds to your decisions, and draws from your world’s characters, locations, relationships, and lore. Explore freely in an open-ended adventure or begin with a structured quest, premise, and goal. PLAY SOLO OR WITH FRIENDS Adventure on your own or invite friends into a shared world for cooperative multiplayer roleplaying. Create a party, explore together, and build a story inside one persistent universe—wherever your group happens to be. YOUR WORLD SHAPES THE STORY Adventure Mode uses the details you created instead of dropping you into a generic setting. Character backstories, relationships, locations, factions, and world lore can all shape what happens next. Your choices influence the story, and your adventure builds upon the world around you. PLAY AT YOUR OWN PACE Customize the experience to match the kind of story you want to tell. Adjust story pacing, response length, and how often the game master suggests possible actions.
