PPTX.ai vs
Gamma
Gamma and PPTX.ai both write a presentation from a sentence or a document. Gamma goes further on files: it exports PowerPoint and PDF, and makes documents and websites too. PPTX.ai goes further in the room: polls and quizzes your audience answers on their phones while you talk.

01 / The short answer
Which one is for you?
Choose Gamma if
- You need a PowerPoint or PDF file to send, or to present from PowerPoint.
- You also want documents, one-pagers or simple websites from the same tool.
- Nobody needs to answer anything during the talk.
Choose PPTX.ai if
- You are presenting to a room and want to hear from it: live polls, quizzes and word clouds.
- You want the assistant to write the questions along with the slides, in the right places.
- You want to check, with a quiz, that the important part landed before you move on.
02 / The same talk, made two ways
A talk with a poll
and a quiz in it.
Here is how you would put one together in each.
With Gamma
- Generate the deckFrom a prompt, or import a document, PDF or existing slides.
- Add interaction elsewhereGamma has no live polls of its own; embed a form from another tool.
- Present or exportPresent from Gamma, or export to PowerPoint, PDF or Google Slides.
With PPTX.ai
- Describe it, or attach a PDFOne request covers the slides, the polls and the quiz.
- Change what you likeEdit a slide yourself, or ask the assistant. Describe the look you want.
- Present itThe room scans a QR code and answers on their phones. You reveal the results.
03 / In the room
The part a deck can’t do.
A Gamma deck is something you show. A PPTX.ai presentation is also something the room answers, and the results appear behind you.
These are real PPTX.ai slides: the big screen behind you, and a phone in the audience.
Example: the poll “Which shift would you pick?” filling in on the big screen as people answer on their phones.
