P.A.U.L.A. SG is the next generation of the Paula software. It's rewritten from scratch, and the artificial intelligence - its understanding and learning capabilities are superior compared to any older versions. It includes an Artificial Intelligence engine, simulating a human being. It learns, understands and feels. Emotions like happiness, anger, and even sexuality are just some of the simulations P.A.U.L.A can perform. You'll be amazed she's not real!
