GryzAn AI that knows your
Apple life
Cloud AI logs everything. Offline chat apps know nothing.
Every mainstream AI assistant — ChatGPT, Gemini, Siri, Claude — sends your queries and context to a remote server. Your sensitive health, legal, and financial questions are logged. Personal notes and calendar events leave the device.
Offline apps solve the privacy problem, but they are generic. They don't know your schedule, your contacts, or your documents. They are blind to your actual life.
You need an AI that understands your context without ever sending it anywhere.
