Kai's verdictA-tier. HeyGen wins for creators, Synthesia wins for enterprise.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
