| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier. Niche but beloved. If you've outgrown Notion, try this. | S-tier for solo + free. The best free option, hands down. | A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google. |
