## What is 49AGI?

49AGI - Private AI, Fully On-Device

49AGI is a powerful AI assistant that runs entirely on your device. No cloud, no API keys, and no internet required for AI inference. Your conversations, images, and documents stay private and never leave your phone.

Powered by Phi-4 Multimodal (3.8B parameters) with Metal GPU acceleration, 49AGI delivers fast, intelligent responses directly on your iPhone or iPad.

CHAT WITH ON-DEVICE AI
Enjoy natural, real-time conversations with a state-of-the-art language model. Get fast streaming responses, organize chats into Work and Personal categories, search your history, and revisit past conversations anytime.

ANALYZE IMAGES AND DOCUMENTS
Attach photos, screenshots, or PDFs to your messages. 49AGI can understand visual content and extract meaning from documents, summarizing, explaining, or answering questions entirely on-device.

AI-POWERED SMART NOTIFICATIONS
Turn conversations into actionable reminders. Create one-time or recurring notifications (daily, weekly, monthly), organize them by category, search easily, export to PDF, or secure them with a password.

BUILD YOUR PERSONAL KNOWLEDGE BASE (SPACES)
Spaces is your private, on-device memory. The AI automatically generates searchable Q&A pairs from your conversations using semantic search. Add your own entries and protect everything with optional password locking.

COMPLETE PRIVACY
- All AI processing runs locally on your device (Metal GPU acceleration)
- No account required, fully anonymous
- No API keys, subscriptions, or hidden fees
- Nothing is sent to external servers
- Optional password protection for Notifications and Spaces
