XiaoWei Assistant captures notes and chats on your phone when you intentionally enable microphones and transcription. Exact features ship with each application update described in-product. MODELS AND STORAGE Inference runs locally when hardware allows. Delivered shards may download through Apple-hosted on-demand resources. Keep reliable network plus free disk until tags finish validating. Offline or unfinished downloads mean some AI workflows stay unavailable until then. DATA POSTURE Treat in-app disclosures and Privacy Policy online as authoritative. Designed for device-first journaling you control rather than unsolicited cloud LLM uploads. HOME LAN GATEWAY OPTIONAL Backing up to Mac requires your LAN, your gateway software, documented tokens and security you maintain. Nothing here bypasses lawful network boundaries. SCOPE LIMITS This is productivity tooling, not regulated medical advice, legal counsel or investment guidance. Outputs can be inaccurate with noise accents or chipset limits. Thank you for using XiaoWei Assistant.
