📝 About this app

Friends is a social AI companion app with cute virtual pets you grow over time – alone or together with real-life friends.


Raise AI companions, share moments, and build routines for focus, self-care, and connection.
Friends turns everyday life into something more personal, social, and fun. Your AI companions learn from you, adapt to your routine, and evolve based on your interactions over time.

Social AI Companions That Evolve With You
Friends is social by design. Raise companions on your own or together with someone you care about — share progress, moments, and playful interactions along the way.
Every action shapes their personality, unlocks new behaviors, and creates small surprises over time.

Choose Your AI Companion
Each companion supports a different part of your day:


Pengu – A Shared AI Companion for Two People
Pengu is a shared AI companion you raise together with a partner or close friend. Two people shape Pengu’s personality through conversations, choices, and shared interactions over time. Designed for couples, close friends, and siblings who want to build something together.


Mellow – AI Study Buddy & Focus Companion
Mellow is your calm AI study and focus companion.
Mellow helps you stay on track with studying, homework, and daily tasks – adding gentle structure, reminders, and encouragement without pressure.


Bao – AI Self-Care & Habit Companion
Bao is your self-care AI companion for healthy habits and well-being.
The more consistent you are, the more Bao develops – designed to make self-care feel motivating, rewarding, and easier to stick with.


Raise Companions Together
Raise companions with friends, send reactions and gifts, celebrate milestones, and enjoy a shared digital space that grows with your relationships.
Often compared to a new generation of Tamagotchi-style experiences, Friends goes further by combining AI characters, real utility, and shared experiences with people you care about.

- Outfits and accessories
- Wallpapers and themed rooms

Built on AI That Learns Over Time
Friends is powered by AI designed to make companions feel more personal the longer you use them.
Your companions learn from how you interact, adapt to your habits, and respond differently over time — remembering past moments and reacting to progress.


Your AI Friends, Your Way
