Best for	Pitch decks, proposals, internal presentations — fast.	Engineering teams offloading tickets. Ops/platform work.	Teams with GitHub already. Devs who don't want to change IDEs.	Replacing Google for any question where you want a cited answer in seconds.
Strengths	Strong templates Decks, docs, webpages Doesn't look generic	Works like an engineer — takes Slack tasks, opens PRs Handles multi-hour engineering work Reports back with what it did	Great enterprise story Works in your existing IDE Chat + autocomplete	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context
Weaknesses	Locked into Gamma's format Export quality varies	Expensive Best for well-scoped tasks Not for solo hobbyists	Less agentic than Cursor/Claude Code Model quality varies	Not a general chatbot Answers can be shallow on complex topics
Kai's verdict	A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.	A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
