About Cory Parry
I build native Mac apps and AI tools, and write about the work behind them.
The work I make
I’m Cory Parry, the maker of Interval, Treebar, and Intents. My projects start with practical problems: keeping a meeting day in view, following coding agents and their changes, and understanding how an AI model behaves.
I work with Swift, SwiftUI, and Apple’s Foundation Models to build native software for the Mac. This website brings the apps together with notes about building, learning, and sharing the results.
Apps and developer tools
Treebar
Follow Codex and Claude Code in Treebar’s Mac agent inbox. Inspect Git worktrees, revisit saved History, and review developer cache cleanup.
Interval
Meet Interval, Cory Parry’s Mac meeting companion for calendar countdowns, call links, and notes. Explore the app, requirements, and current availability.
Intents
Evaluate Apple Foundation Models on Mac with repeatable test suites, scoring, traces and baseline comparisons. Connect coding agents through the built-in MCP server.
How I approach the work
I’m interested in making software clear and useful: understanding the problem, trying an approach, and checking what actually works. Native Apple development, AI implementation, and workflow automation are recurring themes in my projects.
The project pages show what each app does, who it is for, and where to find its current release. My writing shares the decisions and lessons that sit behind the finished product.
Writing and connections
Read my essays on building software, working with AI, and making the work visible. You can also find me on GitHub for public projects and code.
Get new releases by email when I have a new app or update to share.
