Turning a YouTube video into a mind map

Watching a long lecture video and trying to remember how its ideas connect is hard, so a free AI mind map generator can turn the material into a clear structure before you study. DeckOwl does not read video links directly, so copy the transcript or your notes into a plain text file and it builds the map from that text.

  • Accepts PDF, DOCX, PPTX, plain text, and photos of pages read with text recognition
  • Mind maps are editable and explorable, so you can reshape them as you learn
  • Free plan: 3 generations per month with no credit card required
  • Students get 40% off Plus with a school email

Upload notes or transcripts

Paste a video transcript or your notes as text, or upload PDF, DOCX, PPTX, or a photo of a page.

Editable, explorable maps

Expand and collapse branches, rename nodes, and rearrange topics until the map matches your course.

Free to start

The free plan includes 3 generations a month and study in the browser. No credit card is needed to begin.

How it works

Get the transcript or notes

Copy the captions or your own notes from the video into a plain text file.

Generate the mind map

Upload the file and DeckOwl builds a map of the main ideas and their subtopics.

Explore and edit

Open branches, adjust nodes, and study the structure in your browser.

Once the map is generated, you can explore branches, drill into subtopics, and edit nodes so the structure matches your course. The free plan includes 3 generations a month and lets you study in the browser, while exports require a paid plan.

For the best results, use a transcript with clear sections and remove any filler lines before uploading. Then check the finished map against the video once to confirm the main points are right.

Frequently asked questions

How do I turn a YouTube lecture into study notes?

Copy the captions or transcript into a plain text file, then add any notes you took while watching. Break the text into sections by topic so the main branches are easy to see.

How many main branches should a mind map have?

Most lecture topics work well with 4 to 7 main branches, each holding 2 to 4 subpoints. If you need many more, split the material into two maps.

Can I export the mind map for free?

The free plan lets you study in the browser but does not include exports. Plus, at $39/year or $7.99/month, adds PDF, DOCX, Anki, and CSV export.

Do I need a credit card to try it?

No. The free plan gives you 3 generations per month and requires no credit card. Students can get 40% off Plus with a school email.
