Options depend on device and app version. - Local generation runs on the device. Model downloads, account features, and optional sync can still need the network. - Your own provider receives the text submitted to it; its usage charges and data policies apply. - TypeAide Cloud is an online service; follow in-app setup and check current usage limits. - Keyboard AI is optional, works only in supported fields, and cannot read whole conversations or send messages automatically. - Offline keyboard AI, where offered, is experimental and subject to extension memory and device limits. - Review generated content before copying, inserting, or sending it. - Contact: support@duetpagent.top. Never send API keys or private text in a bug report.
