The free AI already on your Mac. CLI tool, OpenAI-compatible server, and interactive chat — all on-device via Apple Intelligence. No API keys, no cloud, no downloads.
apfel is a macOS command-line tool and local OpenAI-compatible server that exposes the language model built into Apple Silicon Macs through Apple Foundation Models. Mac users and developers use it for on-device prompts, shell pipelines, interactive chat, and applications that support OpenAI-compatible APIs. Catalogue add-ons provide agent workflows that use apfel as a local AI backend.
