Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for model-shopping. I use this for every prototype before committing.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
