Strengths	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context	Works like an engineer — takes Slack tasks, opens PRs Handles multi-hour engineering work Reports back with what it did	Socratic — doesn't give answers, asks questions Trusted by schools + parents Integrated with Khan Academy curriculum	Best text rendering in the game Strong free tier Good for logos, posters, thumbnails
Weaknesses	Not a general chatbot Answers can be shallow on complex topics	Expensive Best for well-scoped tasks Not for solo hobbyists	K-12 focus (not deep for adults) Slower than general chatbots	Aesthetic ceiling below Midjourney Less style variety
Kai's verdict	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.	S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.	S-tier for text-in-image. Use this for posters, Midjourney for art.
