Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Google-only Can be slow on large corpora	Can feel overwhelming for non-coders Expensive at scale	Overlaps with general chatbots Workflow setup takes time
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.	A-tier for ops automation. B-tier for simple copy (use Claude).
