STACK Assist is an AI-powered chat tool that helps you quickly find the information you need in your project plans. Think of it as an on-demand estimator and knowledgeable teammate—you can ask construction questions, and it will pull answers directly from the text in your uploaded drawings.
Available to AI Accelerated users, STACK Assist can only read searchable text from your plans. It can’t interpret images or perform actions inside your project.
Use STACK Assist anytime you want to locate requirements, understand assemblies, or clarify project details without digging through dozens of plan pages yourself.
