EnglishWhat types of study materials can Gizmo turn into flashcards?
Updated
Gizmo can convert several common study-material formats into AI flashcards, based on the tools listed on its site: PDFs, PowerPoint files, YouTube videos, and notes. If your material is in one of those formats, you can likely run it through the matching converter. The site also lists a general Flashcard Maker, a PDF Summarizer, a PowerPoint Summarizer, and a YouTube Summarizer, so the same source material can be turned into either a summary or a set of quiz cards.
Supported material types
The homepage lists these conversion tools directly:
| Source material | Gizmo tool |
|---|---|
| PDF documents | PDF to Flashcards, PDF Summarizer |
| PowerPoint files | PowerPoint to Flashcards, PowerPoint Summarizer |
| YouTube videos | YouTube to Flashcards, YouTube Summarizer |
| Notes | Notes to Flashcards |
| Anything you type in | Flashcard Maker |
The site's own description says you "input in what you are learning" and the AI turns it into AI flashcards. So the practical rule is: if you can get your material into one of the formats above, it fits the workflow.
How the conversion works
- Pick the matching tool for your material — for example, PDF to Flashcards for a lecture handout, or YouTube to Flashcards for a revision video.
- Provide the source — the file, the video link, or your notes, depending on the tool.
- The AI generates flashcards from that content.
- Quiz yourself in the app, which uses spaced repetition and active recall, presented in a gamified way.
The expected result is a set of quiz-ready cards drawn from your own material, rather than cards you write by hand.
What this means for your decision
- Good fit: your notes, slides, PDFs, or YouTube-based learning content are already digital and text- or speech-based.
- Check first: material in formats not listed (for example, handwritten scans or audio files that aren't YouTube videos) isn't covered by the tools named on the page.
- Also useful if: you want a summary rather than cards — the Summarizer tools cover PDF, PowerPoint, and YouTube.
The site's testimonials are from students using it for subjects like social studies, science, history, and AP Biology, which suggests the converters are aimed at standard school and exam revision material. The page doesn't state file-size limits, supported languages, or whether a login is required for each tool, so confirm those in the app before relying on a specific format.
