Free PowerPoint summarizer
Upload a .pptx and get a clear summary of what the deck actually says. We read the slides and the speaker notes. No signup, no card.
Free to use. Free to keep.

This free PowerPoint summarizer reads a lecture deck and writes a short version of it. Bullet points on a slide rarely say much on their own, so we read the speaker notes as well and summarise both together. You get sections you can skim before an exam, not a wall of copied bullets. No sign up and no card.

Why use this powerpoint summarizer
Slides and notes together
A bullet says little on its own. The speaker notes say what the bullet meant.
Sections, not a wall
The summary comes in parts you can skim, with the headings the deck used.
Chain the other tools
One upload feeds flashcards, a quiz, key points and a mind map. No second read.
Read it aloud
Press Listen and the summary is read to you while you walk.
Who it's for
Students
Skim ten decks before an exam instead of clicking through four hundred slides.
Anyone who missed the lecture
Read what the deck said in a couple of minutes.
Working professionals
Get the point of a training deck without sitting through it.
Questions
How long can the deck be?
Up to 50 MB. Very long decks are trimmed to the part the AI can read in one go.
Do you read the speaker notes?
Yes. They usually carry more than the slides do.
Can I get flashcards from the same deck?
Yes. Run the summary, then use the row of buttons under the result to make flashcards or a quiz from the same upload. No second read of the file.
Is it free?
Yes, no account and no card.
