I'm Ash, an independent developer building AI tools for the hardware you own, across Apple Silicon and NVIDIA systems.

SparkPilot is my app for using a DGX Spark from your iPhone, iPad or Mac, with guided setup, model controls and chat. It's available through TestFlight, and I'm continuing to develop it as a free app with no ads.

Through Vontra, I publish free MLX model conversions on Hugging Face, with setup notes, testing results and known limitations.

My open-source projects include OpenBOT, a desktop app that brings agent CLIs into one place; TensorFold, an experimental runtime for running models with less resident memory; and Cortheon, an alpha runtime that helps agents check evidence and task completion.

If you've found one of my models or tools useful, buying me a coffee helps cover compute, storage and the time spent building, testing and fixing things. Support is optional, the public models stay free, and a contribution doesn't buy a guaranteed release or priority support.

You can explore SparkPilot at sparkpilot.dev, find my models at huggingface.co/Vontra, and browse the code at github.com/ashhart.

Thanks for supporting my work.
