Alberta is a local-first email RAG/search app that keeps your inbox off the cloud. It syncs IMAP accounts, indexes mail locally (DuckDB + FAISS), and runs the LLM via Ollama. You can search and also chat with your emails to get grounded answers. Search is hybrid (BM25 + vectors) with reranking, adaptive retrieval, and verification to keep answers grounded in real emails. Built for fast latency and multi-account privacy-by-design.
