Pick a theme. CritKit builds a complete dungeon room by room — encounters, traps, loot, puzzles, and a boss chamber — in seconds. Free to try, no signup required.
Building a dungeon from scratch takes hours. You need a layout that makes spatial sense, rooms with distinct purposes, encounters balanced to your party's level, traps with appropriate DCs, treasure distributed across the whole complex, and a boss chamber that feels like a climax. CritKit's AI dungeon generator handles all of it in a single generation.
Type in a theme — an undead crypt, a flooded dwarven mine, a wizard's collapsed tower — and the generator builds a complete dungeon with multiple rooms, each fully described. Every room gets environmental details, interactive elements, and its own challenge: a monster encounter with stat blocks, a mechanical trap with disarm DCs, a puzzle with solutions, or a hidden cache of loot. The boss chamber gets a phase-two mechanic and signature treasure.
What sets CritKit apart from older random dungeon generators is narrative coherence. Rooms connect to each other logically. The faction that controls the dungeon shows up in the decor, the graffiti on the walls, and the monsters chosen. The lore of the setting shapes what you find. A dungeon isn't just a list of rooms — it's a story the players explore.
The cross-import system is CritKit's biggest differentiator: import NPCs from your library as named dungeon inhabitants, drop saved encounters into specific rooms, pull loot tables for custom treasure distributions, and inject world lore to shape factions, deities, and history throughout the dungeon. No other free AI dungeon maker lets you build a dungeon that's already woven into your campaign.
CritKit supports D&D 5e, Pathfinder 2e, and other popular systems. Party level and dungeon size are configurable. Free accounts get 5 generations per month — no credit card required.
Each room gets a name, purpose, full description, and unique challenge — monster encounter, trap, puzzle, or discovery. No blank squares.
Balanced combat encounters placed throughout the dungeon with stat blocks and tactics scaled to your party's level and size.
Mechanical traps with trigger descriptions, effect details, and disarm DCs. Puzzles with clues and solutions ready for the table.
Treasure spread across rooms, not just dumped in the boss chest. Magic items, gold, and consumables placed where they make sense.
The final room gets a proper climax: a phase-two mechanic, environmental hazards, signature loot, and flavor that ties back to the dungeon's story.
Download any dungeon as a clean, printer-friendly PDF to use directly at the table. Subscribers also get Markdown and text formats.
