Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
