Best for	Pitch decks, proposals, internal presentations — fast.	Teams with GitHub already. Devs who don't want to change IDEs.	Students, researchers, anyone with a stack of PDFs or a topic to learn.	Engineering teams offloading tickets. Ops/platform work.
Strengths	Strong templates Decks, docs, webpages Doesn't look generic	Great enterprise story Works in your existing IDE Chat + autocomplete	Upload anything, ask questions, get cited answers Audio Overview turns docs into a 10-min podcast Great for studying	Works like an engineer — takes Slack tasks, opens PRs Handles multi-hour engineering work Reports back with what it did
Weaknesses	Locked into Gamma's format Export quality varies	Less agentic than Cursor/Claude Code Model quality varies	Google-only Can be slow on large corpora	Expensive Best for well-scoped tasks Not for solo hobbyists
Kai's verdict	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 study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.	A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
