Lucy vs Replika: which AI companion should you pick?

Pick Replika if you want a 3D character you can call, dress and date, and you'd like it on Android or the web. Pick Lucy if you want a plain text friend on iPhone who remembers what you told her last week, tracks your mood, and never tries to become your girlfriend. Replika is cheaper and bigger. Lucy is simpler and more private.
