Why? Why ask for this from the creator?
If someone can create new software and offer it for free, they should not also be expected to also create a comprehensive analysis of what other people did and list of differences.
Just take it or leave it, it’s that simple. No need to act as if you’re trying to waste some door-to-door salesman’s time.
Edit: I expected some downvotes but not that many.
To my defense, the question in this thread is “you could elaborate what exactly you did different than all the others”. Look, I’m not a native English speaker either but I feel we could agree that is still pretty far away from simply being curious about design choices or “what led you to create this” sort of exploratory question.
I might have overreacted, though, so sorry for that.
Some people see “free stuff”, and assume that it’s now open season on wasting OP’s time.
It’s a good way to kill any enthusiasm. Imagine your kid made a spaghetti portrait as a gift for you and instead of just accepting it you asked, “but what exactly did you do differently from all kids on the block?”
