Kai's verdictB-tier. Still early. Manus is more flexible for less money.A-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
