Describe what is to be built. Splendit draws, calculates and checks in your model – architecture, structure, HVAC and plumbing, electrical, fire, sprinklers and accessibility.
Requires Revit or AutoCAD, Claude Code or Codex, and your own paid AI subscription.
Splendit works like an entire design team in the same file, in the right order, and makes sure the disciplines agree with each other.
All disciplinesRules and recipes written by architects, reference libraries read when exact values are needed, and lessons from projects already done.
How Splendit knows what it knowsAsk mode to only analyse. Three levels of approval when it is to build. Checkpoints make everything reversible.
