About Withcorpus

A 30-second experiment to see how much personal context your AI remembers about you. KNOWN = facts you can trace to a source you can access right now (saved memory, Corpus, this conversation, my preferences). If either section is empty, say so instead of filling it. Your AI may remember things you've explicitly told it, have access to saved information, or infer things from context.
