| Kai's verdict | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | S-tier for academic research. Nothing else comes close for systematic reviews. | A-tier. Niche but beloved. If you've outgrown Notion, try this. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. |
