How to turn a YouTube video into an AI mind map

Long YouTube lectures are hard to review, and an AI mind map from a YouTube video shows how the ideas connect at a glance. DeckOwl reads text, PDFs, DOCX, PPTX, and photos of pages, so it cannot take a video link directly. Copy the transcript or type your notes first, then upload them.

  • Paste a transcript or notes instead of a video link
  • Edit branches after the AI draft is ready
  • Expand and collapse sections to focus on one idea
  • Start free with 3 generations a month and no credit card
Example Pythagorean theorem mind map branches
Pythagorean theorema² + b² = c² · c is the hypotenuse · applies only to right triangles · c is the longest side
Converse of the theoremIf a² + b² = c², the triangle is right · Used to test whether three sides form a right angle · Confirms a right triangle from side lengths
Finding a missing legRearrange to a² = c² − b² · Subtract the squares before taking the square root · Check that the leg is shorter than c
Common Pythagorean triples3-4-5 · 5-12-13 · 8-15-17 · Multiples such as 6-8-10 also work
Distance formulaDerived from the Pythagorean theorem · Horizontal and vertical legs form the triangle · Used in coordinate geometry

Editable map

Rename, move, or add branches after the AI builds the first draft.

Explorable branches

Collapse or expand sections to focus on one topic at a time.

Study the same material

Use the same upload to practice with flashcards or quizzes.

How it works

Copy the transcript

Open the video, copy its transcript, or type your notes into a text file.

Upload or paste

Add the text, a PDF, or a DOCX to DeckOwl.

Explore and edit

Open the mind map, expand branches, and fix anything the AI missed.

Once the map is built, check each branch against the video timestamps and rearrange anything that does not match the lecture. The map stays editable, so you can add examples and remove filler as you go.

Frequently asked questions

How should I organize a mind map from a math video on the Pythagorean theorem?

Put the statement a² + b² = c² at the center, then add branches for the right-triangle condition, the hypotenuse, and worked examples. Keep each worked example as a sub-branch so you can review the steps separately.

How can I check that a video mind map is accurate?

Compare each branch against the timestamps in the video and against your textbook or class notes. Test yourself on any branch you cannot explain from memory, then fix the map.

Can I export the mind map as a file?

Exporting to formats such as PDF and DOCX is included in the Plus plan, which costs $39 per year or $7.99 per month. The free plan lets you study in the browser without exports.

Is there a free plan, and do I need a credit card?

The free plan includes 3 generations per month and browser study. You do not need a credit card to start.
