# AI Mind Map Generator for YouTube Videos and PDFs > SumAI turns a YouTube video, article or PDF into a mind map on iPhone and iPad. See the whole topic at a glance, zoom in, and share the map as an image. - Source: https://getsumai.app/features/mind-map-generator/ - Last updated: 2026-11-12 - About: SumAI: YouTube & PDF Summary, an AI summarizer app for iPhone and iPad **The whole topic. At a glance.** SumAI turns a summary into a mind map: the main idea in the center, a branch for each subtopic, and the key details on each branch. Zoom in, tap a branch, and share the map as an image. ## Highlights - **Structure first.** A mind map shows how the ideas in a video or document relate before you read a single paragraph. - **Zoom and tap.** Pinch to zoom in on a branch. For videos, branches carry timestamps you can tap to jump to that part. - **Share as an image.** Send the map to a study group, drop it into a presentation, or keep it with your notes. - **No drawing required.** The map is generated from the same content as the summary, so it takes no extra work. ## What a mind map shows that a summary cannot A summary is linear: first this, then that. Most topics are not. They have a central idea, a handful of subtopics, and details hanging off each one. A mind map draws that shape. In the example on SumAI's App Store page, a lecture called "Learn anything faster" sits in the center, with branches for the forgetting curve, spaced repetition, the Feynman technique, sleep and active recall. Each branch carries its two key details and the time in the video where it is discussed. You can take that in within a few seconds, which is the point. ## When to open the mind map - **Before reading.** Look at the branches to see what the video or document covers and decide where to spend your attention. - **While studying.** Use the map as the skeleton of your notes, one section per branch. - **Before explaining.** If you have to present or teach the topic, the map is your outline. - **When revising.** Cover the map, try to redraw the branches from memory, then compare. ## What the research says Mind maps are popular, and the evidence deserves a careful reading rather than a slogan. The strongest research is on **concept maps**, diagrams of ideas joined by labelled links. A [2006 meta-analysis](https://doi.org/10.3102/00346543076003413) by Nesbit and Adesope found that using concept maps was associated with better knowledge retention. A [2018 follow-up](https://doi.org/10.1007/s10648-017-9403-9) by Schroeder and colleagues, covering 142 effect sizes, reported a moderate overall benefit and, notably, a larger effect when learners **constructed** maps than when they **studied** maps made by someone else. Studies of mind maps specifically are fewer and smaller, so it is fair to say they are promising rather than proven. The practical lesson: a generated map is a strong starting point, and you get more out of it by doing something with it. Redraw it from memory. Add a branch of your own. Explain one branch aloud. ## How it fits with the other tools The mind map is one of several views SumAI builds from a single source: - The **summary** tells you what it says. - The **mind map** shows how it fits together. - The [**quiz and flashcards**](https://getsumai.app/features/flashcards-and-quizzes/) check what you remember. - [**Ask AI**](https://getsumai.app/features/ask-ai-chat/) fills in whatever is still unclear. Used in that order, they take you from first look to actually knowing the material. ## How to make a mind map from a YouTube video on iPhone 1. **Summarize the video in SumAI.** Paste the link or share the video from the YouTube app, then choose a style and a language. 2. **Open the mind map.** Open the Mind Map for that summary to see the topic laid out as a central idea with branches. 3. **Zoom, tap and share.** Pinch to zoom, tap a time to jump to that part of the video, and use the share button to export the map as an image. ## Frequently asked questions ### Can AI make a mind map from a YouTube video? Yes. SumAI creates a mind map from a YouTube video that has captions: the main topic in the center with a branch for each subtopic. You can zoom in, tap a branch and share the map as an image. ### Can I make a mind map from a PDF? Yes. SumAI builds the mind map from the summary, so it works for PDFs with selectable text and for web articles as well as for videos. ### Can I export or share the mind map? Yes. SumAI lets you share a mind map as an image, which you can save, send or add to your notes. ### Do mind maps actually help you learn? Research on concept maps, a close relative of mind maps, is positive: a 2018 meta-analysis by Schroeder and colleagues found a moderate overall benefit for learning, with a larger effect when learners built maps themselves than when they studied ready-made ones. A sensible approach is to study the generated map, then redraw it from memory.
