No affiliation with either of you. But, it does not look the same to me. The linked HN post is a simple MacOS top bar tool that shows my list of to-dos that may be activated by key bindings if I wish.

Yours looks more like the default Cmd+Space action - Spotlight available in MacOS.

I personally prefer the simplicity of the app that lives in the top bar as it comes with lower cognitive load by not needing to remember some keywords to summon your tool that is not in my active view.
