Can ChatGPT turn slides into notes? What works and where it fails
ChatGPT can summarise a PowerPoint, but the result depends on your prompt, drops speaker notes, and thins out on long decks. Here is the prompt that works, and when a dedicated tool is the better choice.

Students ask this a lot, and the honest answer is: yes, with caveats that matter for exams.
What ChatGPT does well
Upload a .pptx and ask for notes, and you get readable prose in seconds. For a short deck of 10 to 20 slides with clear bullet points, that prose is usually fine. You can also ask follow-up questions, which no converter tool offers: "explain slide 7 like I am new to this", "what would an exam ask about this section".
Where it goes wrong
Three failure modes come up again and again.
It adds things. Asked to make notes, a general assistant tends to be helpful: it fills in a definition the slide did not give, adds an example from general knowledge, rounds a number to something tidier. For an exam set from these slides, that is the wrong direction. The fix is in the prompt, below, but you have to repeat it every time.
It drops the speaker notes. The speaker-notes pane is where lecturers write the explanation they say aloud, and it is the most valuable text in many decks. File uploads to chat assistants do not reliably include it. You can copy the notes out of PowerPoint and paste them in, which is slow on a 40-slide deck.
It thins out on long decks. Past about 25 slides, the first half of the deck gets careful notes and the second half gets a paragraph. The model is not reading less; it is budgeting its answer. Splitting the deck into two uploads helps, as does asking for a fixed structure.
The prompt that works
If you use ChatGPT for this, paste something like the following with the file:
Turn these slides into study notes. Rules: use only what is in the slides; do not add any fact, example or definition that is not there. Keep every number, date, name and formula exactly as written. Use a heading per topic, merging slides that cover one idea. Explain each bullet in a full sentence. Skip title, agenda and thank-you slides. If the file includes speaker notes, fold them into the topic they belong to. Write in the language of the slides.
That prompt is roughly what a dedicated tool sends on every run, which is the point: the difference between a chat assistant and a slides-to-notes tool is mostly that the tool has the right instructions built in and reads the file properly.
When a dedicated tool is the better choice
Use Nuutli instead of a chat assistant when any of these is true: the deck is over about 20 slides; it has speaker notes; you want a specific format such as Cornell notes, flashcards or a study guide; or you want a Word file rather than text in a chat window. It reads the .pptx structure directly, speaker notes included, keeps every fact exact by default, and returns the notes in about 30 seconds without a prompt to write. It is free and needs no account.
Use ChatGPT when you want to have a conversation about the deck afterwards. Many students do both: notes from the tool, questions in the chat.
