About ModelPiper
A one-person studio building local-first AI tools for macOS
What ModelPiper Is
ModelPiper is a local-first AI platform for macOS. It lets developers and power users build, run, and chain AI tools entirely on their own hardware, with no cloud accounts, no per-token billing, and no data leaving the device. The platform includes a visual pipeline builder, a native macOS inference engine (ToolPiper) with over 420 MCP tools, browser automation, self-healing test recording, voice AI, screen capture, and audio mixing.
The product suite runs on Apple Silicon and ships as a free DMG download (ToolPiper) plus free Mac App Store companion apps and a free web interface. All AI processing, including LLM inference, speech-to-text, text-to-speech, OCR, pose detection, and image upscaling, runs on-device using llama.cpp, Apple Intelligence, CoreML, and Metal GPU.
ModelPiper is headquartered in the United States and is an independent, bootstrapped company.
Founder
Ben Racicot
Founder & Lead Engineer
Ben Racicot is the founder and lead engineer of ModelPiper. He designs and builds every layer of the platform, from the Swift macOS apps and inference backends to the Angular web interface and MCP server protocol. Before ModelPiper, Ben spent over a decade building web and native applications, with a focus on real-time systems, developer tooling, and performance engineering.
ModelPiper grew out of a conviction that useful AI tools shouldn't require cloud subscriptions or giving up your data. Ben built it because the tools he wanted didn't exist: a local inference engine that works like a platform, not a chatbot.
