GeoSync

GeoSync is a city comparison app that lets people search two cities and view their boundaries side by side at the same real-world map scale. try it at https://geosync.willstark-lab.workers.dev The idea came from a simple curiosity: wanting to compare places I already know, like two cities, neighborhoods, or familiar locations, at the same scale without manually matching zoom levels across separate maps. GeoSync turns that spatial curiosity into an instant side-by-side comparison, making it easier to understand how places relate in real-world size. On the technical side, It normalizes OpenStreetMap/Nominatim geometry, computes area, bounds, and centroids, keeps MapLibre panes scale-locked, and generates shareable comparison URLs with OG preview images. And hosted on CloudFlare.

Reverse TOS turns unreadable terms of service into plain English. It shows what a company really gets, what rights the user gives up, and which clauses are actually worth worrying about. The web app comes preloaded with major platform policies like Instagram, TikTok, Discord, and X, and also supports analyzing a pasted TOS URL.

Fieldnotes + HVE for Codex

Fieldnotes is a mission control dashboard that visualizes the Research → Plan → Implement → Review (RPI) pipeline across all your projects. It scans your local repos, finds HVE workflow artifacts, and surfaces confidence levels, implementation progress, and review verdicts in one view, eliminating digging through markdown files to know where a task stands.
