Phronesis

A local workspace that carries decisions, sources, and context from one AI session to the next. It captures what changed after the work and brings the relevant decisions back before your AI answers. You approve what becomes current, and everything stays in plain Markdown on your own disk.

Works with Claude Code and Codex.

I'm a product leader in Phoenix, currently working on AI and platform capabilities for small-business software. Before that, I led product in marketing technology, business communications, and property-management software. Phronesis is a tool I built for myself to get the most out of Claude Code and Codex for knowledge work and coding.
