It's an awesome tool. Actually, it's two tools in one: an AI interface and a part that lets you build automations that work with the AI part. I don't have it fully figured out yet, but The AI tools I've seen don't get you much in the way of automation, and automation tools don't offer much in terms of AI-driven interactions. Pickaxe bridges that gap.
Oh, yeah, forgot to mention it also lets you wrap your logic up in a nice package and charge money for it. Verrrrryyy smart of them!
