Kai's verdictS-tier for solo + free. The best free option, hands down.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier. Niche but beloved. If you've outgrown Notion, try this.
