## What is M5Chat?

M5Chat is an AI chat assistant that runs entirely on your device.

【Multi-Engine, One App】
· Remote models: connect to the LLM services you already use, with your own accounts and credentials
· On-device inference: llama.cpp local GGUF models, MLX CoreML, Apple Foundation Models (Apple Intelligence)
Switch engines in one app. Credentials stay in your iOS Keychain.

【iPhone Duo Dual-Screen】
Optimized for foldables: single column on the cover screen, automatic two-pane layout when unfolded — conversation list on the left, chat on the right.

【Agent Capabilities】
Built-in tool calling: file reading, code execution planning, Wiki knowledge base generation — an AI that gets real work done.

【Privacy First】
Conversations are stored locally on your device only. No account, no tracking, no middleman servers. Credentials are secured by the iOS Keychain.

【Localized】
Full Chinese UI, built natively in SwiftUI.
