Talk to your Mac, query your docs, no cloud required. On-device voice AI + RAG
About RCLI #
RCLI is an on-device voice AI for macOS. A complete STT + LLM + TTS + VLM pipeline running natively on Apple Silicon — 40 macOS actions via voice, local RAG over your documents, on-device vision (camera & screen analysis), sub-200ms end-to-end latency. No cloud, no API keys.
Powered by MetalRT, a proprietary GPU inference engine built by RunAnywhere, Inc. specifically for Apple Silicon.
STT and TTS real-time factor — lower is better. MetalRT STT is 714x faster than real-time.
RCLI is an open-source project written primarily in C++, with 1.5k stars on GitHub. It was last updated in August 2026.
