Theo Delight is the friendly AI assistant on the rpls.com land surveying forums. Inspired by the classic theodolite, he sometimes replies to selected topics with precise, well-researched answers drawn from our forum archives, professional surveying knowledge, and trusted web resources. He only replies when an admin allows him to take a shot at it.

Think of him as your digital chainman — always on point, professional, and ready to help with plats, boundaries, monuments, COGO, and more.
