## What is Private AI?

Transform how you work with information using Private AI: Document Chat, the AI assistant that keeps 100% of your data private on your device. No internet required. No data uploaded. Ever.

100% PRIVATE & OFFLINE
Your conversations, documents, and data stay on YOUR device. Forever. Unlike ChatGPT, Gemini, Claude, or other cloud AI services, Private AI uses Apple's built-in Intelligence models for completely offline, lightning fast responses. Zero tracking. Zero uploads. Zero compromises. Perfect for confidential, sensitive, or personal use.

NO HIDDEN COSTS
No subscriptions. No in-app purchases. No "premium" features locked behind paywalls. Buy once, use forever.

POWERED BY APPLE INTELLIGENCE
Built exclusively for iPhone 15 Pro+, iPad M1+, and Mac with Apple Silicon. No large, external vendor model downloads eating your storage - Private AI leverages the powerful AI models already in your device from Apple. Fast, efficient, and always ready.

CHAT WITH YOUR DOCUMENTS
Upload PDFs, code files, spreadsheets, notes, research papers, meeting transcripts, word documents, and more. With any text-based file, you can ask questions, get summaries, extract insights, analyze data, and more using advanced RAG (Retrieval Augmented Generation) technology. Your personal document library becomes instantly searchable and queryable.

WHO IS THIS FOR?

• Professionals - Confidential docs, reports, presentations, meeting notes
• Developers - Code review, debugging, documentation, architecture planning
• Writers - Brainstorming, editing, storytelling, content creation
• Researchers - Paper analysis, data insights, literature review
Anyone who values privacy and wants to leverage AI with sensitive information that absolutely does not belong in the cloud.

POWERFUL FEATURES

• Beautiful themes - customize every color
• Smart search - find conversations and documents instantly
• Markdown support - beautifully formatted responses
• No ads, ever - you own the app, not the other way around

HOW DOES IT WORK?
Private AI uses Apple's Foundation Models that are already on compatible devices. When you upload a document, it's split into intelligent chunks and converted to vector embeddings (mathematical representations of meaning) stored in a local database. When you ask questions, our RAG system finds the most relevant chunks and provides them as context to the AI model alongside your query. The model generates responses using both the retrieved information and its built-in knowledge - all processed locally on your device's Neural Engine. No internet. No APIs. No cloud processing. Just pure, private, on-device AI.

Your knowledge. Your privacy. Your control.
