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.

ReplyPilot helps you prepare thoughtful, contact-specific replies for the moments when you cannot answer right away. Choose the people you trust, write a fixed fallback reply, and control how each rule behaves. ReplyPilot then guides you through the personal Message automation Apple requires in the Shortcuts app. REPLY ON YOUR TERMS • Create named rules for selected contacts • Turn automatic replies and AI drafting on or off per rule • Edit the fallback reply directly from the rule card • Set response delays, schedules, cooldowns, daily limits, and urgent phrases • Train a local writing style with guided questions • Add a conversation narrative and approved talking points PRIVATE BY DESIGN ReplyPilot does not read your Messages database or conversation history. It processes only the current message that you explicitly connect as Shortcut Input. Rules, selected contacts, writing examples, and safety history stay on your iPhone. On compatible devices, drafting uses Apple’s on-device intelligence features; a fixed local reply remains available when on-device drafting is unavailable. HONEST APPLE SHORTCUTS SETUP Apple does not allow third-party apps to create, inspect, enable, or send from a personal Message automation on your behalf. ReplyPilot gives you a guided setup and opens Apple Shortcuts at the correct point. Apple Shortcuts controls the trigger, and Apple’s Send Message action sends the prepared reply. FREE AND PRO The free plan supports one person and up to five automatic replies per day. ReplyPilot Pro is a one-time lifetime purchase that unlocks unlimited people and unlimited daily replies. No subscription. Automatic behavior depends on the personal automation and permissions you approve in Apple Shortcuts. Availability of on-device AI varies by iPhone model, language, region, iOS version, and Apple Intelligence status.
