| Kai's verdict | B-tier. Still early. Manus is more flexible for less money. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | A-tier. Niche but beloved. If you've outgrown Notion, try this. | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. |
