I get where you're coming from - Copilot is very cheap and useful! We want the free version of CodeViz to be as useful as possible for you. Some features, like the second architecture layer, are just expensive for us.

Personally, I spend a small fraction of my time actually typing code and much more time gathering context & building a mental map. CodeViz speeds up the mental map part, so we hope to deliver much more value than $19/mo

Let me know if there's anything missing from CodeViz that would change your mind!
