ChatGPT wrote my deck's content. Gamma made it presentable. That order matters.

People keep asking chatbots to 'make a presentation about X' and getting a markdown file with asterisks where slides should be. I did it for a year. The content was usually decent! The output was never a deck — it was a script pretending to be one. Gamma exists because that gap is annoying enough to pay for.

My current flow for a client pitch: outline the argument in ChatGPT first, including the parts I'll cut. It's better at pushback — I'll say 'poke holes in this story' and get useful objections. Then I paste the surviving outline into Gamma and let it build. Gamma's layout taste is genuinely good, and editing a Gamma deck is faster than fighting PowerPoint shapes.

The reverse order fails in a specific way. If I start in Gamma, it generates plausible slides full of generic claims — 'Streamline your workflow with powerful insights' — and I spend the next hour deleting filler. Pretty is not the same as argued. The thinking has to happen before the slides exist.

Where ChatGPT alone still wins: tiny decks. Five internal slides for a Tuesday meeting, my team shares raw text and nobody makes slides at all. Gamma earns its keep the moment the deck will be seen by someone whose opinion matters — clients, investors, a conference room.

Pricing is close enough not to decide it. If you only present occasionally, ChatGPT plus a template is fine. If decks are a weekly thing, Gamma pays for itself in hours saved, as long as you bring it an argument instead of asking it to have one for you.
