Turning a video into a map you can study from

Long lectures and explainers, like a YouTube video on the solar system, are hard to review because the key ideas are spread across an hour of talk. A mind map from a YouTube video pulls those ideas onto one page of branches you can scan in seconds. DeckOwl does not open video links, so start with the captions or notes you already have.

  • Copy captions or your notes into a plain text file before you upload
  • Add slide screenshots as images and let text recognition read the words
  • Edit the map so any branch the AI misread is corrected before you study
  • Exporting to PDF or DOCX is part of the Plus plan, at $39 per year or $7.99 per month
Example solar system mind map branches
The SunProduces energy through nuclear fusion of hydrogen into helium · Holds about 99.8% of the solar system's mass · Surface is about 5,500 °C
Inner planetsMercury · Venus · Earth · Mars, which are all rocky with solid surfaces
Gas giantsJupiter and Saturn are mostly hydrogen and helium · Uranus and Neptune are ice giants · Jupiter has more mass than all the other planets combined
Asteroid beltLies between Mars and Jupiter · Mostly rocky and metallic bodies · Ceres is the largest object in it
Kuiper beltLies beyond Neptune · Contains icy bodies, including Pluto · A source of many short-period comets

Works from your notes

Upload a PDF, DOCX, PPTX, plain text file, or a photo of a page, and the text is turned into a mind map.

Editable and explorable

Adjust branches, rename ideas, and expand or collapse sections as you go through the material.

Study from the same material

Turn the same notes into flashcards with spaced repetition or a quiz with explanations when you want to test recall.

How it works

Gather the text

Copy the captions or your own notes from the video into a text file. DeckOwl works from text you provide, not video links.

Upload or paste

Add the file or paste the text. Slide screenshots work too, since text recognition reads the words on the page.

Explore and edit

Open the mind map, expand the branches, and fix anything the AI placed in the wrong spot.

Use the map as a review tool: cover a branch, say its sub-points out loud, then check yourself against the map. When you are ready to test recall, the same material can become flashcards or a quiz with explanations.

Frequently asked questions

Can DeckOwl make a mind map straight from a YouTube link?

No. DeckOwl works from files and text you provide, such as captions, a saved transcript, or your own notes. Paste or upload that text and the mind map is built from it.

How many branches should a solar system mind map have?

Five to seven main branches usually works well, such as the Sun, inner planets, gas giants, asteroid belt, and Kuiper belt. Put each planet or group under its own branch with two or three facts.

How do I study notes from a science video?

Pause often and restate the main claim of each section in your own words. Then test yourself from the map without looking, and return to the parts you missed the next day.

Are exports included in the free plan?

No. The free plan lets you study in the browser with 3 generations per month. Exporting to PDF, DOCX, Anki, or CSV requires Plus, which is $39 per year or $7.99 per month.
