How It Works
Zero-Store Direct Forwarding

Direct Query Forwarding

ChatUCY works by directly forwarding your query to a large language model for processing — without storing any data. This ensures your privacy while providing fast and intelligent responses. All chat history is saved only on your device.

LLM-MS additionally routes each query to the most suitable model using multi-armed bandit and overperformer-underperformer selection algorithms.
