Retrieve from Trusted Content
(RAG & Semantic Search)
Access is limited to curated, predefined sources. Each agent retrieves only from content explicitly permitted for its purpose (e.g., a tax assistant accesses only the official Swiss tax websites).
This ensures safe, accurate, and context-appropriate retrieval—especially important for children or sensitive domains.
Integrates Natively with Your Device
Seamlessly connects to calendars, files, camera, reminders, and sensors.
Supports on-device actions like creating reminders, launching apps, or accessing local content.
