Weaknesses	Locked into Gamma's format Export quality varies	Google-only Can be slow on large corpora	Less agentic than Cursor/Claude Code Model quality varies	Terminal-only Less agentic than Claude Code Setup on Windows is fiddly
Kai's verdict	A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.	S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
