| 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. | S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up. | A-tier. HeyGen wins for creators, Synthesia wins for enterprise. |
