Functionality and applications
By using Kurisu's thesis to convert human memory into digital data, Amadeus is capable of creating a fully functional artificial intelligence with all the capabilities and memories of the person whose data is using.
As explained by Maho Hiyajo, Amadeus' capabilities of storing memory data make it possible to back-up the data of a person's memories. This could be useful, for example, to fight against memory loss.
Amadeus in Steins;Gate 0
Amadeus was first introduced during Alexis Leskinen's lecture about Amadeus itself, along with Hiyajo Maho, where they booted up an artificial intelligence based on Hiyajou Maho's memory data.
After Rintaro Okabe shared his experience with Kurisu Makise (who he had met Alpha Attractor Field) to Maho Hiyajo, she later introduced him to an A.I. based on Kurisu's stored memories, and was given the chance to act as a tester for the program. After he accepts, he is given a mobile application that allows him to contact the Amadeus Kurisu.
