Hmm... I'm trying to figure out what's the merit of each of these projects.
Claude claimed there was a reference to marmot, not only mls, in the code of keychat. I can't find any. Grrr.
To me, whitenoise sounds simpler and more targeted for integration in more clients.
Also searching for "mls chat nostr" on duckduck or google brings up a lot of white noise but almost no keychat. There's others but WN appears to dominate right now.
