A classic email client with local AI on your Mac. Privacy first — no cloud, no fees. AI generates replies and calls tools for context. Cortex Mail — Smart Email Client with Local AI Cortex Mail is a classic email client for macOS that combines reliable email management via IMAP and SMTP with the power of a local large language model (LLM). Your data never leaves your computer — all AI processing runs directly on your Mac thanks to the built-in llama.cpp engine. KEY FEATURES • Full-featured email client — connect to any mailbox via IMAP/SMTP, multiple accounts, folders, and search • Local LLM on your Mac — no cloud APIs, no token fees, full privacy control • Tool calling — the AI can actively gather context: search older conversations, look through files, and retrieve additional information • Connect to information systems — just describe how to access the data, and Cortex Mail can pull information from your company system, API, or database • Smart reply generation — AI suggests email replies using the full conversation context and available information • Model catalog — download an optimized model directly in the app, or use your own GGUF file • GPU acceleration — leverages Metal for fast inference on Apple Silicon PRIVACY FIRST All emails and AI processing stay on your computer. Cortex Mail sends no data to external servers. The language model runs locally via llama.cpp — all you need is a Mac with Apple Silicon. TOOLS AND CONTEXT Cortex Mail is not just a passive text generator. With tool calling, the AI can actively search for relevant information — browse your previous emails, look into files on disk, or query an external information system. Just tell it how to access the data. Supported interface languages: Czech, English, German, French, Spanish.
