With OSINT a lot of the fun is in uncovering the information, finding connections, uncovering useful data that leads to the next node and so on. Assuming you know where to look, or how to analyse the data in the first place that is.
Using AI in OSINT investigations isn’t cheating if it helps unblock you, or helps you make progress where you were stuck. It may suggest alternative sources, or recommend tools. It can be like having a virtual OSINT investigator with you whenever you need it. You still have to drive, to direct, to be able to think and ask the right questions in order for it to be of use. It’s not cheating if you are learning.
