About
Your AI assistant that never phones home.
Blossom runs entirely on your iPhone — no servers, no cloud, no data collection. Just you and a powerful AI, completely private.
◆ TRULY PRIVATE AI
Every conversation stays on your device. No account required. No data uploaded. No tracking. Your privacy label speaks for itself.

Ask anything — get thoughtful, detailed responses powered by state-of-the-art language models running locally on Apple Silicon. Works offline, works everywhere.
◆ WORKS WITHOUT INTERNET
On a flight? In the subway? In a dead zone? Blossom works anywhere your iPhone goes. No Wi-Fi or cellular connection needed.
◆ FAST & NATIVE
Built with Apple's MLX framework for blazing-fast inference on iPhone's Neural Engine. No waiting for server responses. No buffering. Instant AI at your fingertips.
◆ CONVERSATION HISTORY
Pick up where you left off. Your chat history is stored locally and never leaves your device.
◆ CUSTOM SYSTEM PROMPTS
Personalize your AI assistant's behavior. Make it a writing coach, coding buddy, brainstorming partner, or anything you need.

A clean, distraction-free interface that puts your conversation first. Designed for iPhone with native SwiftUI.
◆ NO SUBSCRIPTIONS REQUIRED
Get started for free. No ads. No data harvesting. No compromises. Optional Pro upgrade for unlimited conversations and persistent history.
— WHY BLOSSOM? —
Unlike cloud-based AI assistants that send every word you type to remote servers, Blossom processes everything on your iPhone. Your questions about health, finances, relationships, and personal matters stay exactly where they should — with you.
Perfect for:
• Sensitive questions you'd never ask a cloud AI
• Working offline on flights, commutes, or in remote areas
• Users who value digital privacy and data sovereignty
• Anyone tired of AI apps that monetize their conversations
Download Blossom and experience AI the way it should be — private, fast, and always yours.
