Yeah, I've noticed that phenomenon as a general trend in Jams, which is also understandable given browser use is a significantly lower barrier to trying out a project.
I ended up adding a browser-based demo of the speech/audio produced by my tool in an attempt to at least demonstrate the kind of output possible. (Not that it had an impact AFAICT but I at least had fun creating the demo. :D )
If my tool didn't require another tool (speech synthesis system) in order to function at all, I probably would've tried to create at least minimal/cutdown support for browser use/demo.
