Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Academic-only Can hallucinate citations — verify everything	Pricey for serious volume Long shots still feel off Ethics — easy to misuse	Smaller community Model selection more limited
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for academic research. Nothing else comes close for systematic reviews.	S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.	A-tier. Close second to Cursor. If $5/mo matters, start here.
