Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier. Category-defining UX. If you take notes in meetings, switch this week.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier. If you're on Vercel/shadcn, this is cheating.
