I got tired of closed-source macro tools. Most of them store macros in binary formats, have poor DPI awareness, and install global keyboard hooks. For a tool that essentially injects input, closed source felt uncomfortable.
So I wrote my own.

, variables, and screen conditionsFour approaches, ordered from cheapest to most expensive:
Windows UI Automation by name
No coordinates, no thresholds. Works well for normal desktop apps. Almost useless in games that draw their own UI.
Image search
You paste a screenshot snippet (Win+Shift+S). I added the ability to restrict the search area. On my 1440p monitor this dropped the average step from ~78 ms to ~7 ms.
OCR via the built-in Windows engine
No external models to download.
Fixed coordinates
DPI-aware and anchored to the target window.
The majority of the code was written with an AI agent. I directed the architecture, reviewed every part, fixed the non-trivial pieces (especially the image-search optimization and proper DPI handling), and made the design decisions. The final codebase is still normal, readable Rust.
SendInput
can be detected by some anti-cheatsNo telemetry, no accounts, no ads.
I’m mainly looking for feedback on the architecture and any better approaches for the image search / OCR parts.
