AI Mind Map Maker

A mind map is a diagram that starts from one central topic and branches outward into related subtopics. It is a fast way to capture how ideas relate to a single subject and is widely used for brainstorming, note-taking, studying, and planning.

Heuristica is an online mind map maker that uses AI to generate, expand, and organize mind maps. You can build a mind map from any topic, from a YouTube video, PDF, or podcast already saved in your library, or from a blank canvas you grow by expanding nodes with AI.

You have two main paths. Open any resource in your library (a saved YouTube video, PDF, podcast, article, or study deck) and pick Create Mind Map from the sidebar to turn it into a hierarchical tree. Or open a blank mind map, type a central topic, and use Expand with AI to grow the branches.

Mind maps start from one central idea and branch outward in a tree structure, which makes them great for brainstorming and note-taking. Concept maps connect multiple ideas in a network with labeled links between them, which is better for showing how concepts relate. Heuristica supports both, so you can pick the structure that fits the task.

Yes. Heuristica has a free plan that lets you create mind maps, expand nodes with AI, and explore the rest of the study tools. You can upgrade for higher limits and access to more AI models.

You can generate a mind map from a topic you type into a blank canvas, or from any resource already saved in your Heuristica library, including YouTube videos, PDFs, podcasts, articles, and study decks. Save the source first, then open it and pick Create Mind Map.

Right-click any node and pick Expand with AI. The AI looks at the node and its context inside the map, then adds child topics that fit. Run Expand on the root node for a deeper, broader exploration of the whole subject.

Export is not available yet but it is on the roadmap. You will soon be able to export a mind map as an image or as markdown, and import markdown from other mind map tools into Heuristica.

You can keep expanding the mind map with AI, edit and rearrange the nodes, and use it as a visual outline of the subject you are studying.

Mind maps are generated exclusively with Google Gemini, which gives the best results for the structured, hierarchical output a mind map needs.

Yes. You can set the AI to respond in over 20 languages, so the mind maps you generate match the language you are studying in.
