Best for	Developers who want an agent, not autocomplete. Large refactors, tests, docs.	Replacing Google for any question where you want a cited answer in seconds.	Students, researchers, anyone with a stack of PDFs or a topic to learn.	Knowledge workers + thinkers who want AI in their second brain.
Strengths	Runs locally, edits your actual files Strong on large codebases with 1M context Great at multi-step tasks	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context	Upload anything, ask questions, get cited answers Audio Overview turns docs into a 10-min podcast Great for studying	AI auto-links related notes Generates backlinks + summaries Clean, minimal UX
Weaknesses	Terminal-based — learning curve Can't be used without Claude subscription	Not a general chatbot Answers can be shallow on complex topics	Google-only Can be slow on large corpora	Expensive for just notes Smaller community than Obsidian
Kai's verdict	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.	A-tier. Niche but beloved. If you've outgrown Notion, try this.
