Best for	Teams with GitHub already. Devs who don't want to change IDEs.	Long writing, code, careful thinking, documents over 50 pages.	Knowledge workers + thinkers who want AI in their second brain.	Engineering teams offloading tickets. Ops/platform work.
Strengths	Great enterprise story Works in your existing IDE Chat + autocomplete	Best-in-class writing + nuanced reasoning 1M context on Opus Artifacts for code/docs Lowest hallucination rate in my testing	AI auto-links related notes Generates backlinks + summaries Clean, minimal UX	Works like an engineer — takes Slack tasks, opens PRs Handles multi-hour engineering work Reports back with what it did
Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Image generation is weak No native web search on all tiers	Expensive for just notes Smaller community than Obsidian	Expensive Best for well-scoped tasks Not for solo hobbyists
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.	A-tier. Niche but beloved. If you've outgrown Notion, try this.	A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
