| Kai's verdict | A-tier. Close second to Cursor. If $5/mo matters, start here. | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. | A-tier in its niche. The only one that actually gets emotion right. | A-tier. S-tier if you self-host. The reason open-source image gen matters. |
