PPTX.ai vs
Mentimeter
Both put polls and quizzes in front of a room while you talk. Mentimeter has more kinds of question and Q&A. PPTX.ai is built around the slides as much as the questions: it writes and designs the whole talk, and the questions arrive in the right places.

01 / The short answer
Which one is for you?
Choose Mentimeter if
- You need audience Q&A, or question types like 100 points, 2×2 grids or pin on image.
- You want people to answer without signing in.
- Your slides already live in PowerPoint and you only want to add questions.
Choose PPTX.ai if
- You are starting from a sentence or a PDF and want the whole talk written: slides, polls and quiz together.
- You want the slides themselves designed, not imported as pictures.
- You only want to pay when the assistant writes something. Presenting and your audience’s answers are free.
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 Mentimeter
- Build the MentiAsk its AI assistant, or add slides and questions one by one.
- Bring in your deckImport a PowerPoint or PDF (the slides become images), or use the PowerPoint add-in.
- Present itPeople join with a code at menti.com or a QR code.
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
Both run the room.
Here the difference is before you walk in. PPTX.ai writes the slides around the questions, so the poll comes right after the slide it is about.
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.
