How to make flashcards from a video you are studying

Lecture videos pack a lot into one sitting, and rewatching is a slow way to review. A set of AI-made flashcards from a YouTube video lets you test yourself on the key terms in minutes instead.

  • Paste the transcript or notes as plain text, then upload the file.
  • Skim auto-generated transcripts for misheard terms before generating.
  • Keep one idea per card so each answer can be checked in seconds.
  • Review the missed cards more often than the ones you already know.
Example periodic table group flashcards
Which group are the alkali metals in?Group 1. They are highly reactive and have one valence electron.
What is the name of group 17?The halogens, including fluorine, chlorine, bromine, iodine and astatine. They readily gain one electron.
Why are the noble gases in group 18 so unreactive?Their outer electron shell is full, so they rarely gain, lose or share electrons.
What do elements in the same group share?The same number of valence electrons, which gives them similar chemical properties.
What is the name of group 2?The alkaline earth metals, such as magnesium and calcium, which have two valence electrons.

Works from your transcript

Paste a video transcript or your own notes as plain text. Anything you can copy into a file works.

Spaced repetition built in

Cards return at the intervals where you are about to forget them, so the lecture's ideas stick.

Export when you need it

The free plan studies in the browser. Plus adds PDF, DOCX, Anki and CSV export.

How it works

Copy the transcript

Open the transcript panel under the video on YouTube, or type your key points into a text file.

Upload and generate

Upload the file and DeckOwl writes flashcards from the material.

Review on schedule

Study the cards, and spaced repetition brings back the ones you miss.

DeckOwl reads plain text, so the reliable route is to copy the transcript from the video page or type out your own notes, then upload that file. Auto-generated transcripts can contain errors, so skim them first, because a wrong term becomes a wrong card.

Cards work best when each one tests a single idea. Ask for definitions, causes and comparisons from the lecture rather than whole paragraphs, then review them with spaced repetition.

Frequently asked questions

Can DeckOwl make flashcards directly from a YouTube link?

No. DeckOwl accepts PDFs, DOCX, PPTX, plain text, notes and images, so copy the transcript or your notes into a text file and upload that.

How many flashcards should I make from one lecture?

Keep to one idea per card and stop once the main points are covered. A short lecture rarely needs more than a few dozen cards.

How should I study the periodic table groups with flashcards?

Start with group names such as alkali metals and halogens, and their typical behavior. Then quiz yourself on which group each element belongs to before moving on.

Do I need to pay to export my flashcards?

Yes. The free plan studies in the browser, while Plus at $99.90/year or $9.99/month adds PDF, DOCX, Anki and CSV export.
