Leaf: Eco AI Chat

Private, offline AI chat that lives entirely on your iPhone.

Leaf pairs a calm, botanical interface with Apple’s on-device Foundation Model so you can brainstorm, write, summarize notes, and work through code—even in Airplane Mode. No cloud servers. No accounts. No subscriptions.

WHY LEAF IS DIFFERENT

• 100% On-Device & Offline — Every prompt and response is generated locally on your iPhone using Apple Intelligence. Zero data leaves your device, and zero water or cloud data-center energy is used.
• 4-Layer Context & Memory Engine — Inspired by modern LLM memory systems, Leaf combines session context, long-term user memories, recent chat summaries, and a smart token-based sliding window so it remembers who you are across conversations.
• Transparent, Editable Memory — Leaf automatically learns your preferences, skills, and goals as you chat—or you can add, edit, and delete memories anytime in the built-in Memory & Context Inspector.
• Smart Cross-Chat Summaries — When you switch topics, Leaf summarizes past threads on-device so you can pick up right where you left off.
• No Account & No Subscription — Open Leaf and start chatting immediately. No sign-up, no email, no token paywalls, and no recurring fees.

BUILT FOR REAL WORK & EVERYDAY THINKING

• Summarize rough meeting or lecture notes into crisp checklists
• Draft warm, concise replies and emails without filler
• Debug code, compare architectures, and brainstorm weekend projects
• Pin important threads and inspect real-time token capacity at a glance

YOUR WORDS STAY YOURS

In a world of cloud AI that harvests conversations for training, Leaf takes a quieter, local-first approach. Your thoughts stay on your phone—we can’t read them, and we never will.
