LEGO Block Build Plans Prompt Generator
Real‑Build Mode: only existing LEGO/BrickLink parts • structure‑first • BrickLink‑ready BOM • Buildability Score
A prompt is the clear set of instructions you give an AI or creative tool to get the output you want. Use the menus below to assemble a structured brief, then click Generate to produce a clean, copy‑ready block. You can copy an individual concept level or “Copy All.” Adjust menus and Generate again anytime.
