Turn YouTube video notes into AI flashcards

DeckOwl does not read YouTube links, but you can copy a video's transcript or your own lecture notes into a file and get flashcards with spaced repetition in minutes.

Getting flashcards from a YouTube lecture

Lecture videos pack definitions, formulas, and worked examples into a few minutes, and most of it slips away within days. DeckOwl does not pull captions straight from YouTube, but it works well as an AI flashcard generator from a YouTube video once you bring the text yourself: copy the transcript or type your notes into a plain text file and upload it.

Paste a transcript or your typed notes as plain text.
Upload PDF, DOCX, or PPTX slides that go with the video.
Review cards with spaced repetition instead of rereading the video.
Export to Anki or CSV on the Plus plan.

Example electric circuits flashcards from a lecture

What is Ohm's law?V = IR: voltage equals current times resistance.

How do series and parallel circuits differ?In series, current has one path and is the same through every component. In parallel, voltage is the same across each branch and current splits between them.

What does Kirchhoff's current law state?The sum of currents entering a junction equals the sum leaving it, because charge is conserved.

How is electrical power in a resistor calculated?P = IV, which can also be written as I²R or V²/R, measured in watts.

What does a capacitor store?Electric charge and energy in an electric field between two conductors, with capacitance measured in farads.

Generate the full set

Works from your own text

Paste plain text or upload notes, a PDF, a DOCX, or a PPTX file, and DeckOwl turns the material into flashcards.

Spaced repetition built in

Cards come back right before you would forget them, so review time goes to the ideas that need it most.

Export when you need it

Plus users can export to Anki, PDF, DOCX, or CSV, so your video cards can move into the tools you already use.

How it works

Copy the transcript or type notes

Open the video's transcript or write down the key definitions and formulas from the lecture, then save them as a plain text file.

Upload or paste the text

Add the file to DeckOwl or paste the text straight into the generator.

Study the cards on a schedule

Review the flashcards in the browser, and let spaced repetition bring back the ones you miss.

Good cards come from clear source text. Pick the sections that carry the core ideas, such as laws, definitions, and key steps, and skip filler like introductions or sponsor segments. Shorter, focused input usually produces cards you can answer in a few seconds.

Frequently asked questions

How many flashcards should I make from a lecture on electric circuits?

Make one card per distinct law, definition, or formula rather than aiming for a fixed number. Cut any card whose answer you could not explain in a sentence.

Why do spaced repetition flashcards work well for circuit formulas?

Spaced repetition shows each card again just before you would forget it, which helps with formulas like Ohm's law that you need to recall under exam pressure. Short reviews repeated often work better than one long cram session.

Can I export the flashcards to Anki?

Yes, export to Anki is included in the Plus plan at $99.90/year or $9.99/month. The Free plan lets you study in the browser, but exports are not included.

Does DeckOwl work directly with YouTube links?

No, it accepts PDF, DOCX, PPTX, plain text or notes, and images, so copy the video's transcript or your notes into a text file first. The Free plan includes 3 generations per month, and no credit card is needed to start.
