Strengths	Upload anything, ask questions, get cited answers Audio Overview turns docs into a 10-min podcast Great for studying	Strong templates Decks, docs, webpages Doesn't look generic	Great enterprise story Works in your existing IDE Chat + autocomplete	Edit audio/video by deleting text Overdub (voice clone) for fixes Strong collaboration + remote recording
Weaknesses	Google-only Can be slow on large corpora	Locked into Gamma's format Export quality varies	Less agentic than Cursor/Claude Code Model quality varies	Not a traditional NLE — some workflows awkward Overdub ethics require care
Kai's verdict	S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.	A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
