Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier. If you're on Vercel/shadcn, this is cheating.S-tier for realtime. If latency matters more than voice catalog, start here.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
