What This D&D Dungeon Generator Creates
Procedural Layout
Tree-growth algorithm with locally symmetric branches and loop connections creates hand-designed-feeling dungeon layouts instantly.

Detailed SVG maps with thick wall outlines, diagonal hatching, grid floors, and a warm parchment palette.
AI Room Content
Each room can be filled with descriptions, monsters, traps, treasure, and secrets tailored to your theme and difficulty.
Practical guidance
How to Use the D&D Dungeon Generator
Give the dungeon a reason to exist and a pressure that changes while the party explores. Rooms become easier to run when every obstacle supports that purpose.
Start with the dungeon's original use and its current occupier.
Mix information, danger and reward instead of filling every room with combat.
Add at least one route that changes how the party approaches the objective.

D&D Dungeon Generator Questions
How does the dungeon layout work?
The generator uses a tree-growth algorithm inspired by Watabou's One Page Dungeon. It grows rooms from the entrance with locally symmetric branches, then adds loop connections for interesting exploration paths.
Can I use these maps in my campaign?
Yes. The interactive SVG map can be exported as a painted battlemap PNG, and the full room list is printable. All content is generated for D&D 5E, with no other system support yet.
What sizes of dungeon can I generate?
From small (5-8 rooms) for quick encounters to massive (26-40 rooms) for full session dungeons. Each room can include AI-generated descriptions, monsters, traps, and treasure. You can also set an exact count from 3 to 50 rooms.
Is the dungeon generator free to use?
Yes, generating a dungeon is free to start. There are no premium models, batch generation, or richer room content to buy for this generator. Editing is included on the Plus tier and above, and every plan is listed at char-gen.com/pricing.
Can I export or share my dungeon?
Yes. Every dungeon saves to the World Codex, exports its room key to PDF and its painted battlemap to PNG for printing at the table, and can be shared as a public page. You can also export to Foundry VTT, Fantasy Grounds, Obsidian, Homebrewery, Markdown and JSON.
What game systems does the dungeon generator support?
D&D 5E only for now. That is the default and the form has no system picker, so monsters, encounters, and hazards scale with your D&D party level and difficulty; they do not also scale to Pathfinder 2E. Room descriptions and treasure adapt to your theme, and you can reuse that prose in whichever system you pick for your table.
Is it a dungeon map maker?
Yes. Every dungeon comes with a Dyson-style map of its rooms and corridors, and CharGen paints a battlemap from it. Export that battlemap as a PNG to print or to use in your VTT, together with the keyed room descriptions as a PDF.
What can I set before I generate a dungeon?
A size (Small 5-8, Medium 10-15, Large 16-25 or Massive 26-40 rooms) or an exact room count from 3 to 50, one of 8 themes (crypt, mine, temple, sewer, castle, cave, lair or ruins) or your own, a difficulty from easy to deadly, a party level from 1 to 20, monster types, loot rarity, and trap density from none to heavy.
Is it a random dungeon generator?
Yes. Each run grows a new layout at random from the entrance, so the same settings give a different map every time. The AI then keys every room, adds plot hooks and rumours, and writes the history and atmosphere for that layout.

The short answer
What is the CharGen Dungeon Generator?
The CharGen Dungeon Generator is an AI tool that produces procedural Dyson-style dungeon maps with rooms, corridors, traps, encounters, and AI-keyed descriptions for tabletop RPGs. Each generated dungeon includes a named site with a one-paragraph history, a procedurally generated map with 5-40 rooms and corridors (or an exact count from 3 to 50), an AI-painted battlemap of that map, AI-written read-aloud room descriptions, an atmosphere of sights, sounds, and smells, monsters scaled to D&D 5E party level, traps with mechanical effects, treasure placed in the dungeon's rooms, secrets, and plot hooks.
Unlike static dungeon tables, the layout has symmetric branches and is printable, the keying is unique to each generation, and the history, atmosphere, threat and rumours can be regenerated individually. Outputs save to the World Codex, export to PDF, PNG and VTT formats, and share as public pages. Free to start and free to keep using; editing on Plus and above (see char-gen.com/pricing).
