Strengths	Production-grade agent primitives Built on Claude (best reasoning) Full control — build exactly what you need	Best text rendering in the game Strong free tier Good for logos, posters, thumbnails	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
Weaknesses	Developer-only You build the UI	Aesthetic ceiling below Midjourney Less style variety	Not a general chatbot Answers can be shallow on complex topics	Expensive Best for well-scoped tasks Not for solo hobbyists
Kai's verdict	S-tier for builders. The right primitives. What Kai is built on under the hood.	S-tier for text-in-image. Use this for posters, Midjourney for art.	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.
