Nook: AI Companion

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.

SIX BUILT-IN COMPANIONS. ZERO ASSISTANTS.

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.

All memories and conversations stay on your device and sync privately through your iCloud. Nook never stores your personal data on external servers.
