Cool. You might consider describing Muze as a project rather than a product. E.g., On the homepage: Our first product, Muze... -> Our first project, Muze....
I associate "product" with something that is sold, so when I saw Muze described as a "product," but I didn't see a price, I was somewhat wary that the price was hidden or forthcoming.
"Project" is also a fairly common term to refer to open source tools and the community around them. See the nav bars for linuxfoundation.org or numfocus.org, for instance.
^^^ I had the same thought process. I spent a few minutes clicking around the site to figure out the catch to the open-source library that is the only product of a company with a $$$$ domain.
We will be making more products in future, some OS, some paid. So yes, monetization is on the cards :) - but our first goal is to create real good value!
