Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier in its category. The first AI music tool I'd actually listen to.S-tier for speed. When latency is the product, start here.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
