CastIQ AI Mind Map Generator: Visualize How Any Topic Connects

How CastIQ's mind maps work — depth levels, graph vs list view, and when a mind map actually helps more than reading notes top to bottom.

Quick answer

CastIQ's Mind Map feature turns a video, PDF, or your own notes into a visual node map — with three depth levels from a quick skim to a dense breakdown — that you can explore with pinch-and-zoom instead of reading top to bottom.

Some subjects are naturally linear — a set of steps, a timeline. Others aren't: biology, history, and civics especially tend to be a web of ideas that connect back to each other in ways a top-to-bottom page of notes doesn't show well. A mind map is built for exactly that second case — seeing the shape of a topic, not just its content.

What a CastIQ mind map actually shows

  • A root topic with branches and sub-branches — the actual hierarchy of the source material, not a flat list.
  • Three depth levels — skim (fewer levels, fast overview), default (balanced), and dense (a full breakdown of sub-topics).
  • Two ways to view it — an interactive graph you pinch and drag through, or a list/outline view if you'd rather read it as text.
  • Export as an image for offline revision.

Picking a depth

Skim depth is genuinely useful the night before an exam — enough to confirm you remember how everything fits together without re-reading full notes. Dense depth is closer to a full outline and is better suited to first-pass studying or a subject you're building from scratch.

When a mind map beats reading notes

A mind map compresses information — that's its strength and its limit at the same time. It's strongest for final revision (confirming you remember the shape of a topic), for subjects with a lot of interconnected sub-topics, and for spotting gaps — a branch that feels thin usually means that part of the topic needs another look.

How to generate a mind map with CastIQ

  1. 01

    Add a source

    Use a YouTube video, a PDF, or notes you've already generated in CastIQ.

  2. 02

    Pick a depth

    Skim for a quick overview, default for normal use, or dense for a full breakdown of sub-topics.

  3. 03

    Generate

    CastIQ builds the node structure automatically from the source's actual topic hierarchy.

  4. 04

    Explore or export

    Pinch and drag through the graph view, switch to list view to read it as an outline, or export it as an image for offline revision.

A mind map is a revision tool, not a first-read tool — it works best alongside full AI notes for the initial study pass, then a quiz to confirm what actually stuck.

Frequently asked questions

It sets how many levels of sub-branches the map goes down. A shallower depth gives you a fast skim of the main ideas; a deeper setting breaks each branch down further, closer to a full outline of the topic.
