So, it's at most $400 in Claude expenses for a fully custom suite of software in 2 months. Even if your time is 300/h, it's less than $2k in your own time (which, I would expect, you enjoyed spending). That's insanely impressive.
Did you miss a factor of 10 in that time-cost calculation?
As a hobby, normal rates don’t apply, but just not to be misleading on the equivalent cost.
I need Claude Max in any case for my work, so the cost is effectively null. And I do creative stuff in my spare time regardless, and I don't really think about my hourly rate when I play with my kids either ;)
