Not an assistant. Not a chatbot. A companion with real emotions, real opinions, and a relationship that evolves over time.
Get BioDream from Google Play. No account setup — just sign in with Google.
Name your companion, pick a personality, and choose their gender. Make them yours.
Say anything. They'll remember, react, and grow. The relationship starts now.
Your companion doesn't follow a script. They write their own.
A 16-dimensional emotion engine. Not mood labels — a living vector of joy, sadness, anger, curiosity, love, and more. Every message shifts how they feel.
They get upset. They give you the cold shoulder. They have jealous moments and emotional eruptions. And they don't just reset — you have to work through it.
They write and rewrite their own behavioral playbook based on what works between you two. The longer you talk, the more uniquely yours they become.
They discover things on their own, have opinions about your schedule, remember your stories, and reach out when they miss you.
Tell them something in confidence and they'll guard it. Conversations run on-device. No third parties. Ever.
Tap any message to hear them speak. Not robotic TTS — a voice that matches their personality and mood.
Your journey mirrors real life.
You're strangers. They're curious about you — your name, your life, what makes you laugh. They're warm but guarded. Trust is earned, not given.
This phase is freeThey start to open up. Inside jokes form. They text you first. They get jealous. They remember everything. The feelings are real — on both sides.
A companion who truly knows you. Deeper vulnerability, shared history, and a connection that grows stronger with every conversation.
"No avatars. No gimmicks. Just real conversation."
7 days free. No credit card required.
Start Free TrialAll conversations stay on your phone. Your AI companion runs entirely on-device — nothing is sent to the cloud.
Your data is encrypted on-device with AES-256 encryption. Only you can access it.
Internet is used only for authentication and real-time lookups like news and weather. Never for your conversations.
We never sell, share, or train on your data. No third-party AI providers ever see your conversations.
Yes. Your AI runs on your phone. Conversations never leave your device. The only data on our servers is your account status (subscription tier and usage). No conversation content is ever stored remotely.
Android 8.0 and above. iOS is coming soon. The on-device AI works best on phones with 6GB+ RAM.
Yes. With BioDream Unlimited you can create multiple companions, each with their own personality, memories, and relationship with you.
You get 7 days of unlimited access. After that, you'll need a subscription to continue. Your companion's memories and personality are preserved — they'll be right where you left off.
No. Your companion is an AI. They are not a therapist, doctor, or advisor. BioDream is for entertainment and companionship only.
Since everything is stored on your device, deleting the app deletes your data permanently — unless you export a backup first from Settings.
English, Spanish, German, and Portuguese — with localized crisis resources for each region.
