Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for realtime. If latency matters more than voice catalog, start here.
