Starter gets 3 build credits a month, Builder gets 12, and Master Builder gets 30. A Voxel generation uses one credit and a Detailed (beta) generation uses two. If a Detailed generation can't produce a model that holds together, both credits are refunded automatically. Credits reset at the start of each calendar month, and you can always buy +5 credits for £6 on top of your current plan. See the Pricing page for full plan details.

Every generation gives you a full 3D preview (with real colors) for free - you can rotate and inspect the model, and see its part count and color breakdown, without paying anything. “Instructions” is the downloadable .ldr file, full parts list, and a step-by-step PDF build guide - walking through the model bottom-up, layer by layer, with the new pieces for each step called out - included automatically on every current plan (Starter, Builder, and Master Builder). You can also open the .ldrfile in BrickLink Studio (free, search “BrickLink Studio download”) to check the parts list against real BrickLink inventory.

In Voxel mode, color comes straight from the generated 3D model's own surface, then gets mapped onto the closest real, purchasable brick color using a perceptually-accurate color match - so it's a close approximation, not an exact one, especially on faces of the model that came through less clearly during generation. In Detailed mode, colors are picked from real brick colors as the model is designed, so they are exact brick colors, but still an interpretation of your prompt.

Yes - every part in a generated model is a real, standard brick/plate/tile/slope shape. Unlocking a model gets you the .ldr file, a full parts list, and a PDF build guide; from there you can buy the parts from BrickLink or open the .ldr file in BrickLink Studio for its own inventory check.

Voxel generations are built from a 55-part real, purchasable brick library - bricks, plates, tiles, and a wide range of slope angles and curves for smoother, less blocky surfaces. Detailed generations use a 70+ part library that adds curved slopes, round bricks, windows, doors, real wheels, plants, and sideways building (also known as SNOT - “Studs Not On Top”) for more detailed, less boxy shapes. Both are growing all the time as we add new building techniques.

Voxel is strongest on organic shapes - animals, plants, and sculptural forms in particular. Detailed is strongest on buildings, vehicles, and animals, and weaker on very thin or flat subjects (long tentacles, instruments lying flat). Either way, the more specific your prompt, the better the result: describing pose, proportions, or distinctive features gives the generator more to work with than a one-word prompt.

No - your prompt only describes what to build, and the builder picks parts on its own, so instructions like “use curved slopes”, “avoid 1x1 plates”, or “150 to 300 parts” are ignored. In Voxel mode your prompt becomes an image, then a 3D shape, and only then does the brick builder run; slopes and sideways (SNOT) pieces only appear where the shape has a suitable step or flat wall, so smooth curves on things like a bird's back or neck will still come out slightly stepped. In Detailed mode you can choose the building style with the controls under the prompt instead: the finish (smooth tiles or studs showing) and how much sideways building to use. Spend your prompt on the subject: pose, proportions, colors, and distinctive features, and use the build size slider to control how detailed the build is.

We can't guarantee that every generated model will be very physically stable - it depends on what you asked for and how thin or overhanging the shape is. What we can say is that the vast majority of generated models come out with 100% connectivity and few flagged issues on BrickLink Studio's own stability checker, thanks to a built-in support-structure algorithm that automatically finds and braces weak points before a model is finished. Detailed models are checked so every part connects and nothing overlaps, but they don't get Voxel mode's load analysis. Always give a model a quick check in Studio (or by hand) before ordering parts, especially for anything thin, tall, or overhanging.
