Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Writing quality trails Claude/ChatGPT Political bias debates Ecosystem is just X	Image generation is weak No native web search on all tiers	Google-only Can be slow on large corpora
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier for real-time. B-tier for everything else. Worth checking when news breaks.	S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.	S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.
