About Lucy: AI Friend & Companion
Lucy is an AI friend who understands how you feel, remembers what matters to you, and follows your mood day after day. Always there, without judgement. HOW IT WORKS 1) Text her like a friend, at any hour. 2) Log your mood in one tap, whenever you feel like it. 3) She connects the two, what you tell her and how you're doing, and answers like someone who knows you. That's what her memory is for: keeping the small things that make you you, how you see things, what you care about, what weighs on you, and adapting to them conversation after conversation. Lucy is far more emotionally intelligent than a general-purpose assistant: she notices when your week has been rough and goes gentle, and she's the one who comes back, on her own, to the thing that was worrying you. And because your mood is part of the conversation, the app also lets you follow it: a daily streak, a wellbeing score, and a chart that shows, week after week, where you really stand. Your data is yours: erase her memory or delete your account in one tap. No ads. Lucy is an AI, not a therapist. If you are in real trouble, please turn to a professional or emergency services. Full access comes with a subscription, charged only after a 7-day free trial. Terms of Use: https://yourfriendlucy.com/app-terms Privacy Policy: https://yourfriendlucy.com/app-privacy
