Can we use ChatGPT 4o to get takeoffs done? … are you breaking any copyright?

A general chatbot won't give you a reliable takeoff from a PDF plan set; commenters who tried said it bogs down on full sets. Where it does help: explaining a detail, pulling scope notes, and searching a spec book or geotech report. On rights, the drawings belong to someone (usually the architect), and bid documents often come with confidentiality terms. A commenter's advice was to check with your management, and with the document owner, before uploading.
DIY, privacy-first option: run a model locally so files never leave your computer. Install Ollama or LM Studio (both free), then point AnythingLLM (free desktop app) at the spec PDF for question-and-answer. Mac users can also try oMLX. Use it for reading and searching, not measuring; keep measuring in a takeoff tool. Setup: Local AI on a Mac Studio with Ollama.
