| Kai's verdict | A-tier for data teams. S-tier if you already live in SQL + Python. | The concept is genuinely compelling — turning the home screen into a living AI layer is a smarter bet than yet another chat interface — but this is vaporware until it ships publicly and we see whether Apple's sandbox lets it breathe. (Verdict pending Phi's full review.) | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. | A-tier. Niche but beloved. If you've outgrown Notion, try this. |
