An open-source overlay for Age of Empires II: Definitive Edition that reads the screen with OCR, follows a build order step by step, adapts when the player deviates and tells you where to put each villager. It comes with a public web library to share build orders.
- Windows desktop app in C# .NET 10 and WPF: screen capture, Windows OCR and custom digit templates for the game HUD
- Pure C# engine (planner, tracker and economy) with 300+ tests, compiled to WebAssembly so the web simulates with the same engine as the app
- Web library with Next.js 16 and Supabase: row-level security, Discord and Google sign-in, votes and one-click import into the app
- Fair play: it only reads the screen. It never reads game memory, injects code or sends inputs
