What if you had a true AI assistant on your smartphone that works without Wi-Fi, requires absolutely no account registration, and completely protects all your conversations? "Private AI" makes this a reality. This AI runs directly on your iPhone or iPad, not on a corporate server. No internet connection or sign-up needed. Your data is never sent anywhere; every conversation always stays on your device alone. Your Privacy, Fully Guaranteed Most AI apps send your messages to external servers, but Private AI is different. The AI model lives and thinks directly inside your smartphone. This means your questions, ideas, and conversations belong entirely to you. It is perfect for anyone who values privacy—whether you are brainstorming work ideas, writing a personal journal, or discussing sensitive topics. Full-Fledged AI on Your Phone Private AI runs some of today's most powerful open-source AI models, including Gemma, Qwen, Ministral, and Phi. New models are added regularly, allowing you to always experience the latest advancements in AI. Once you download a model, it is yours to keep. You never need an internet connection to chat. Thinking Mode Turn on Thinking Mode to see the AI's reasoning process before it delivers an answer. It visualizes the AI's thoughts, making it perfect for getting deeper, more structured responses to complex questions. Just Speak — Or Just Listen Skip the typing and ask questions with your voice. You can also have the AI read its answers aloud. It is incredibly convenient when your hands are full or when you simply prefer listening. Rich Features for Natural Interactions - Auto-save chat history: Pick up right where you left off. - Edit past messages: Get new answers instantly. - Organize freely: Rename and manage your chats with ease. - Custom AI personalities: Set a unique persona for each conversation. - Save favorite prompts: Quick access whenever you need them. - Adjust AI settings: Fine-tune creativity and focus. How It Differs from Cloud-Based AI Because the AI runs locally on your device, response speeds depend on your phone's hardware performance. While it might not respond instantly like cloud-based AIs, it is completely private. Best of all, its greatest strength is that it works flawlessly even on airplanes or in places with no reception.
