| Kai's verdict | S-tier for solo + free. The best free option, hands down. | A-tier. Niche but beloved. If you've outgrown Notion, try this. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work. |
