| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs. | S-tier for builders. The right primitives. What Kai is built on under the hood. | A-tier for data teams. S-tier if you already live in SQL + Python. |
