Whether you're working on a novel, a short film, a tabletop RPG campaign, or just need a story for tonight: Plot Spark instantly delivers a character, a conflict, and a setting - random, unexpected, and inspiring. HOW IT WORKS Pick a kit, roll the dice - and get a complete story prompt with character, conflict, setting, and a wild twist. Sounds too simple? That's exactly the point. Prefer instant results over a dice animation? Turn the roll animation off and get straight to the prompt.

And you can create your own kits and fill every slot with your own ideas - tuned to exactly the tone you need. JOURNAL & MARKDOWN EXPORT Save every hit straight to your journal. Write notes, develop the idea, or let it simmer - your best prompts won't get lost.
