Top-down AI-generated cave battle map with an underground stream, a rock bridge and glowing blue mushrooms

About the AI Cave Map Generator

Caves are where a lot of adventures go underground, and they are hard to draw well. Natural rock has no straight lines, the interesting parts are the water, the drops and the light sources, and a stock cave map almost never has the chasm or the goblin warren your encounter needs.

The Text to Tabletop AI cave map generator turns a description into a finished cavern. Name the features that matter to the fight (a stream to cross, a ledge to hold, a tunnel the enemies come out of, a pool that hides something) and the generator paints them into a top-down map at battle scale.

Every map is locked to a straight-down view with no baked-in grid, so it lines up with the grid in your virtual tabletop. If one part of the cavern is not right, select that area and regenerate only that part while the rest of the map stays as it is.

Multi-room underground dungeon map with stone corridors and glowing pool
Dungeon Map

Ancient Stone Dungeon

Free download and prompt

Prompt

"A multi-room underground dungeon carved from dark grey stone. A long central corridor connects four chambers of varying sizes. One room has a collapsed ceiling with rubble on the floor. Another has a shallow pool of water glowing faintly blue. Iron doors and archways connect the rooms. Scattered bones and broken furniture. Torches in wall sconces provide dim orange light. Top-down, grid-aligned, dungeon map style."

Snow-covered mountain pass map with frozen waterfall and stone shelter
Wilderness Map

Frozen Mountain Pass

Free download and prompt

Prompt

"A treacherous mountain pass in heavy winter. The narrow path winds between jagged snow-covered peaks. Ice patches and deep snowdrifts partially block the trail. A frozen waterfall clings to one cliff face. A small stone shelter or shrine sits near a switchback. Wind-blown snow obscures the edges. Cold blue and white color palette. Top-down, grid-aligned, battle map style."

Coastal cave battle map with wrecked ship, tidal pools, and stalactites
Battle Map

Shipwreck Coastal Cave

Free download and prompt

Prompt

"A rocky coastal cave where a wrecked wooden ship has run aground. The hull is broken open, with debris and cargo crates scattered across the wet cave floor. Shallow tidal pools reflect the dim light entering from the cave mouth. Stalactites hang from the ceiling. Ropes and torn sails drape across the wreckage. The ocean is visible through the wide cave entrance. Top-down, grid-aligned, battle map style."

Volcanic lair entrance map with lava rivers, stone bridge, and obsidian pillars
Battle Map

Volcanic Lair Entrance

Free download and prompt

Prompt

"The entrance to a lair built into the side of an active volcano. Rivers of glowing orange lava flow through channels carved into dark volcanic rock. A narrow stone bridge crosses a lava stream leading to a massive carved stone doorway. Steam vents and cracks in the ground glow with heat. Obsidian pillars flank the entrance. Charred bones and scorched earth surround the area. Red and orange lighting from below. Top-down, grid-aligned, battle map style."

Use Cases

  • Goblin and kobold warrens: twisting tunnels, sleeping nooks and a chieftain chamber for a classic first-level crawl
  • Underground rivers: fast water, slick rock and a single natural bridge that turns a crossing into a fight
  • Crystal grottos: glowing crystal clusters that give light, cover and something worth stealing
  • Fungal caverns: bioluminescent mushrooms, spore clouds and soft ground for underdark encounters
  • Sea caves: tidal pools, a hidden smugglers' landing and a tunnel that floods at high tide
  • Lava tubes: cooled obsidian floors with rivers of magma still running through the lower chambers
  • Ice caves: frozen waterfalls, slippery floors and a beast's den at the back of the glacier
  • Collapsed mines: cave-ins, abandoned carts and old timber supports that might not hold

Frequently Asked Questions

Everything you need to know about the AI Cave Map Generator.

What kinds of cave maps can I make?

Any cave you can describe: limestone caverns, lava tubes, ice caves, sea caves, fungal grottos, crystal caverns, collapsed mines and monster lairs. Name the rock, the water, the light and the features the fight needs, and the generator draws them.

How do I get tactical features like chasms, ledges and water?

Put them in the prompt. "A chasm splits the cavern with one rope bridge", "a raised ledge along the north wall" or "a shallow pool of black water in the center" all work. The more specific the feature, the more reliably it appears where you want it.

Can I make a cave system across several maps?

Yes. Generate each chamber as its own map with a matching description of the rock and lighting, so the areas feel like one cave system. Separate maps also let you reveal the system to players one chamber at a time.

Will these maps work in Roll20, Foundry VTT and Owlbear Rodeo?

Yes. Maps come out at 1K, 2K or 4K as standard image files, drawn with no grid lines so your virtual tabletop can lay its own grid over them, and Foundry VTT users can also export a .dd2vtt file. They import into Roll20, Foundry VTT, Owlbear Rodeo and Fantasy Grounds like any other map.

Is there a free trial, and what does it cost after that?

Yes. New accounts get 3 free tokens, enough for three maps at 1K or one at 4K, so you can generate a cavern and try a second idea before deciding whether to buy. No credit card required. After that, a $1 trial pack is available once per account, then packs from One More Map at 4 tokens for $2, or a Pro Plan at $10 a month for 50 tokens.

Do my tokens expire?

No. Tokens never expire. Whatever you do not use stays on your account, and Pro Plan tokens roll over from month to month instead of resetting, so a quiet month costs you nothing.

Can I change part of a cave map after it is generated?

Yes. Select the area you want to change, for example to add a tunnel entrance or widen the stream, and regenerate just that area. The rest of the cavern stays exactly as it was.
