Cloud AI is best for maximum capability
Large cloud models can be very strong for complex reasoning, web-connected tasks, and large context workflows. But cloud AI normally requires an internet connection and remote processing.
Private local AI is best for sensitive everyday context
Local AI Chat is designed for prompts that should stay close to you: personal notes, rough drafts, screenshots, private questions, study material, and work ideas that do not need cloud upload.
Local AI also works when cloud AI cannot
Offline AI is useful in airplane mode, during travel, in weak-signal areas, or when a network blocks AI services. Supported Local AI Chat models run on device after the model files are available.
The practical choice
Use cloud AI when you need the largest possible model. Use Local AI Chat when you need a private AI assistant for everyday mobile work without an account, API key, or constant internet access.
