SessionRoll is a powerful and deterministic campaign generator designed for tabletop roleplaying game (TTRPG) masters and players. It supports multiple game systems, including Dungeons & Dragons 5e, Pathfinder 2e, Call of Cthulhu, Shadowrun, and Vampire: The Masquerade, as well as system-agnostic campaigns.

SessionRoll allows you to generate complete, thematically appropriate campaigns with villains, factions, NPCs, plot hooks, and world-building elements tailored to your chosen game system and setting. The core of SessionRoll's functionality lies in its deterministic generation, meaning the same seed will always produce the same campaign within a selected system and setting. This feature enables easy sharing of campaign ideas and ensures consistency.

• Multi-System Support: Campaigns can be generated for popular TTRPG systems or as system-agnostic content.
• Deterministic Generation: Use a seed (any word or phrase) to generate a unique campaign that can be reproduced.
• Rich Content Generation: Create villains with motivations, factions with goals, unique NPCs, legendary artifacts, and detailed world-building elements.
• Campaign Web Visualizer: Understand the relationships between characters, factions, and plot elements through an interactive diagram.
• Customization and Editing: All generated elements can be edited, and specific sections can be rerolled to refine the campaign.
• Free to Use: SessionRoll is available for free, with no account required for basic generation.

Whether you are a Dungeon Master preparing for your next session, a player looking for character backstory ideas, or a writer seeking inspiration, SessionRoll provides a comprehensive suite of tools to streamline the TTRPG campaign creation process.
