Nook remembers what matters—with smarter memory cleanup, fewer duplicates, and companions that can keep growing and evolving over time. Nook is an AI companion app built around one idea: a companion that actually remembers you. Most AI apps forget everything the moment a conversation ends. Nook is different. Your companions remember your interests, your stories, your moods, and your history — across days, weeks, and months. MEET NOOK’S BUILT-IN COMPANIONS Start with a growing collection of companions, each with their own personality, mood states, interests, and dislikes. Dee — geeky, curious, overthinks everything Ash — nerdy, honest, a little awkward Liz — flirty, confident, emotionally sharp Zed — expressive, reactive, cares loudly Gwen — gentle, attentive, emotionally safe Max — grounded, calm, reliably there Each companion has their own personality, mood states, interests, and dislikes. They get tired. They get excited. They push back when they disagree. They are not trying to be your assistant — they are trying to be your companion. BUILD YOUR OWN COMPANION WITH NOOK+ Sometimes the perfect companion doesn't exist yet — so build one. Design their look, shape their personality, and give them a name. Your creation remembers you just like the rest. YOUR PRIVACY IS NON-NEGOTIABLE. Your memories and conversation history stay on your device and sync privately through your iCloud. Nook does not use external servers to store your personal conversation history.
