NEW: AI Helper
Just ask. Type a construction math question in plain English, like "rafter length for a 12 ft run and 6/12 pitch", and the AI Helper works it out and walks you through the steps. It asks for any missing numbers, covers roofing, concrete, stairs, wall studs, footings, blocks, drywall, miters, board feet, conversions and more, and runs entirely on your device, so it works offline and your data stays private.
