Possession is an open-source library that lets an AI agent do more than talk: it actually participates in your app. It navigates, fills in forms, suggests visual options, places orders. Not a chatbot in the corner, a second user that understands your software as well as you do.
Below are four patterns where this is useful, with the demos that illustrate each one. The code behind possession is on GitHub. Demos run on request, ping me and I'll open one for you.
