Lufu is someone to talk to, and people who make things for you. Four companions you can actually see — Mira, Nia, Sofia and Yumi — face to face, over live video. Each has her own face, voice and attitude. Call whoever fits your mood, text her between calls, and she remembers what you told her. Around them, a circle of seven more who read your cards, record you a song, draw a tattoo and put it on your skin, dress you, redo your room and cook from what's in your fridge. Some days you want someone who's glad to see you. Some days you want something made for you. Here, it's both. WHAT'S FREE AND WHAT'S PAID New users get 10 free text messages and a look inside every thread. Video calls, messaging beyond that, and the circle's work require a paid, auto-renewing weekly subscription (Companion, Confidant, or Soulmate). Each plan includes a set number of video minutes and messages per week; messages also pay for what the circle makes (a reading costs 3, a song, tattoo, outfit or room costs 7). Optional one-time top-ups add more. Exact prices are shown in the app before you buy. Without an active subscription or remaining minutes, video calls are not available. FOUR COMPANIONS, FOUR PERSONALITIES • Mira — warm, calm, a little playful. • Nia — the clever one: quick, curious, always has a fact ready. • Sofia — confident and competitive, hard to impress until you do. • Yumi — a brat with a soft center. All four are AI characters, each with her own conversation and her own memory of you. FACE TO FACE, LIVE Not a chat box with a picture. You see her and hear her, and you talk out loud, like a video call with a friend. She sees you too, so she notices how you're really doing. YOUR CIRCLE Seven more, one craft each, a few taps and it's made: • Selene pulls your cards and reads them in plain words. • Asha works out your real natal chart from your birth details. • Iris designs your tattoo, draws it, then places it on a photo of your skin. • Noor writes three takes on the words, you pick and edit one, and he records a real song. • Esme puts an outfit on a full-length photo of you — or the piece you're thinking of buying. • Ivan redraws the room you actually have, around what you want to keep. • Lena turns what's in your fridge into dinner. Everything they make is AI-generated, for you, and yours to keep. MESSAGES AND PHOTOS Text any of them between calls; they answer in their own voice. Ask Nia, Sofia or Yumi for a photo and she'll ask what you'd like to see, then send one made for you. Photos are AI-generated. You can also describe a character of your own and text them the same way. THEY REMEMBER YOU Your name, what's going on in your life, what you told them — on calls and in texts. They pick up where you left off. PRIVATE, AND YOURS TO DELETE Delete a message, clear a thread, or erase everything they remember about you, any time, in the app. IMPORTANT Lufu's characters are AI companions for comfort, connection, conversation and play. They are not real people and not a substitute for professional medical, mental-health, financial or crisis care. Readings are for entertainment. If you are in crisis or thinking about harming yourself, please contact your local emergency services or a crisis line right away. Lufu is intended for adults (17+). — — — SUBSCRIPTION TERMS Lufu offers auto-renewing weekly subscriptions (Companion, Confidant, and Soulmate tiers), each including a set number of minutes and messages per week, plus optional one-time top-ups.
