| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. | 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. |
