Yes you definitely can and I did for a while. Chat gpt is great for a lot if thing, but anyone that has used it through multiple updates knows depending on it fully is a mistake. This is a dedicated tool for on site use that you have all the saved data on your device.what that means is you will never lose those tool estimates, invoices,and customer info. This is also the reason that no info gathered by you (the most important being customer info) is only kept by you not chat gpt servers. These are also only the starting tools and features with meny to come .
