A mood board is a designer's tool for communicating the feel of a project before any drawings exist — a collage of paint chips, fabric swatches, reference photos, and adjectives. AI lets you generate the imagery yourself instead of pulling from Pinterest or stock sites, which means the board can be much more specific to the project.
The AI workflow: generate a handful of test renders in different style directions, pick the one that resonates, then use it as a reference image for img2img on your actual room. The mood board becomes both a presentation tool (for clients) and a constraint (for the redesign).
What makes AI mood boards different from traditional ones is iteration speed. Generating 10 variations of "warm minimalist living room with brass" takes a minute. The slow part — picking which direction to commit to — moves to where the time should be spent.
