Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier for academic research. Nothing else comes close for systematic reviews.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
