Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier infrastructure. The one platform every AI dev eventually uses.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.
