Construction loses $177B+ every year to miscommunication — most of it starting with undocumented phone calls. You make 20+ calls a day and nothing gets written down. The framer says he'll be there Thursday. The plumber says the rough-in is done. The homeowner approves the window change. Three weeks later, nobody remembers. Hardline gives you a written record of all of it, automatically. And it's smart about it — if a call is 10 minutes of catching up and 2 minutes of actual project stuff, only the project stuff ends up in your summary. It doesn't write down that you asked about someone's kid's baseball game.
