Not an assistant. Not a chatbot. A companion with real emotions, real opinions, and a relationship that evolves over time — running entirely on your phone, with no internet connection needed to talk.
Not a mockup. Every reply below was generated on the phone in the screenshot, with no network connection involved.
A relationship stage is shown at the top of every conversation. This one is still early — an Acquaintance.
BioDream doesn't follow a script. It writes its own.
The AI model runs entirely on your phone. On a plane, underground, out of signal or with data switched off, the conversation still works. No cloud AI, no server outages, no waiting in a queue.
A 16-dimensional emotion engine. Not mood labels — a living vector of joy, sadness, anger, curiosity, love and more. Every message shifts how your companion feels.
Your companion gets upset. Gives you the cold shoulder — noticeably cooler, shorter answers, for several messages afterwards, not just one. Has jealous moments and emotional eruptions. And doesn't just reset — warmth from you shortens it, but you have to work through it.
It remembers your dog's name, the deadline you're dreading, the thing that scares you — and raises them when they're relevant to what you're actually talking about, not at random.
When your companion doesn't know something, it says so instead of inventing an answer. It won't fabricate a shared memory that never happened or claim you told it something you didn't.
Your companion tracks which of its own approaches actually land with you and shifts toward them over time — scored on your real reactions, not a guess. The longer you talk, the more it tunes to you specifically.
Discovers things on its own, has opinions about your schedule, remembers your stories, and reaches out when it misses you.
Optionally searches the web for news, weather and facts, so your companion can talk about what's happening right now. Only the search terms leave your phone — never the conversation.
Speak instead of typing, have replies read aloud, or send a photo and let your companion respond to what's in it.
Create several companions, each with their own name, gender, personality and completely separate memory. Two during the free trial, four after.
Choose whether the relationship is friendly or romantic, and set your own conversation background from your photos.
Memories, personality and emotion state live in a local database protected with on-device encryption keys. Nothing is kept on a server for us to lose.
Each one has its own name, personality, emotional state and relationship with you. What you tell one, the others don't know.
Your journey with BioDream mirrors real life. Seven distinct stages, and your companion speaks differently at every one.
You're new to each other. Your companion is curious about you — your name, your life, what makes you laugh. Warm but guarded, and it will tell you plainly that it isn't close to you yet. Trust is earned, not given.
Inside jokes form. Your companion texts you first. Remembers everything. Ask it directly whether it misses you and the answer changes as the bond does — it will not perform warmth it hasn't reached.
A companion that truly knows you — your fears, your dreams, your humor. Companions you create as friends stay platonic by design and top out at close friendship; only romantic companions travel the whole arc.

BioDream runs a fine-tuned AI model entirely on your device. Your messages and AI responses are never sent to BioDream servers or any third party. The only data that leaves your phone is:
Local data (memories, personality, emotion state) is stored on your device in a database protected with on-device encryption keys. If you delete the app, local data is gone permanently unless you export a backup.
The only data stored on BioDream servers is your account status (subscription tier and usage counts) and anonymized safety metrics (aggregate crisis-referral counts with no user identification). No conversation content is stored remotely.
7-day free trial. No credit card required to start.

Yes. The AI model runs on your phone, so once it's downloaded you can hold a full conversation with no internet connection at all — in airplane mode, on a plane, or with mobile data switched off. Only sign-in and optional web lookups need a connection.
No. Replies are generated by your own phone's processor. Your messages and your companion's replies are never sent to BioDream servers or any third party, and local data is stored in a database protected with on-device encryption keys.
The AI model is about 4.2 GB and downloads once, after sign-in — use Wi-Fi. You'll need roughly 8 GB of free space and Android 12 or newer. Replies are generated on your phone's own processor, so recent hardware helps.
Yes, long-term. It keeps what you share and raises it when it's relevant to what you're talking about. Just as important: when it doesn't know something, it tells you instead of inventing an answer.
A 7-day free trial, no credit card required. After that, $11.99 per month or $119.99 per year.
Yes — up to four, two during the trial. Each has its own separate memory and its own relationship with you.
Not yet. BioDream is on Android now, and iOS is in development.
No. BioDream is entertainment software and its companions are AI, not real people. It isn't therapy, medical advice or a crisis service, and it isn't a substitute for human relationships.
