| Kai's verdict | A-tier for data teams. S-tier if you already live in SQL + Python. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs. | A-tier for its niche. Different use case than Suno — SFX and loops, not songs. |
