Character.AI is a platform where millions of user-created characters live, from fictional heroes to celebrity-style personas. It is great for variety. Sammi takes a different approach: instead of an endless catalog, it focuses on your AI girlfriend, with memory, voice, selfies and a relationship that deepens over time.
