Block Dreamer is an AI Minecraft build generator. You describe one structure in plain words, such as a mossy stone castle, a Japanese pagoda or a kneeling knight, and it returns a Minecraft Java 1.21 build made of real blocks with their facing.
Every build opens in a textured 3D view that you can turn, zoom and cut open layer by layer, at any height, to see the rooms inside. Beside it are a layer plan, for building one level at a time in survival, and a block list counted in stacks of 64, largest first.
There are two ways to build. Classic writes the structure block by block from a kit of roofs, walls, towers, stairs and furnished rooms, at the size you ask for. Detailed 3D makes a 3D model of the subject and carves it into blocks, which suits statues, creatures and landmarks.
To put a build in your world, download the vanilla .mcfunction, drop it in a datapack and run one /function command, with no mods or plugins. The same build also downloads as a .litematic for Litematica and a .schem for WorldEdit. On Bedrock the files don't apply, so you build from the layer plan by hand.
To see what it makes before trying it, open the gallery. Every build there is free to open with its prompt, blocks and downloads.
It makes one structure per prompt, and it does not make cities, terrain or redstone machines. There are free credits to start. After that, monthly plans from $4.99 and one-time credit packs from $2.99 pay for more builds.
