Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.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.
