### **ContextOS: Project Description**

**ContextOS** is a local-first, privacy-preserving multimodal recall assistant designed to eliminate "digital amnesia" during daily computer use. It captures semantic snapshots of active workspaces and audio streams, organizing them into a secure, searchable local index using Meta Llama vision models, ChromaDB, and BM25 hybrid retrieval.

For maximum data security, it features a configurable hybrid architecture that runs entirely on-device (`LOCAL_ONLY`) or uses an explicit opt-in privacy gate (`HYBRID_SANITIZED`) equipped with local PII auto-redaction and an interactive review screen before any approved image frames are sent to hosted Meta Llama endpoints.
