Weaknesses	Image generation is weak No native web search on all tiers	Less agentic than Cursor/Claude Code Model quality varies	Expensive for just notes Smaller community than Obsidian	Expensive at scale Still needs post-editing
Kai's verdict	S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.	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.	S-tier. Market leader with reason. Start here for serious video.
