Some tools in domaining, like expired domain sites...they're somewhat AI powered search tools, and do help me. The other categories mentioned...maybe, but not that I can think of with regards to any significant "edge", at least for my needs. Maybe if you're more serious, you'll naturally explore / use more things, requiring further analytics, deeper depths of data...but I'm a simple man. A simple man that looks up expired / expiring domains, has a peak at the odd auction, looks at reported sales, buying domains that are available and solid at a fair price...nothing too clever or in-depth, that maybe others would engage in
