| Kai's verdict | S-tier infrastructure. The one platform every AI dev eventually uses. | S-tier inside Photoshop (Generative Fill). B-tier standalone. | B-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. |
