- Pick "Markdown bullets" or "ASCII tree" as the output format.
- Click Generate Mind Map, then Copy to put the outline on your clipboard.
About this topic mind map generator
A mind map captures a central topic and branches outward into sub-topics, with each sub-topic able to spawn its own deeper branches. This tool gives you a nested editor: every node has a + button that adds a child, an × button that removes the node (and everything underneath it), and an editable title. The vertical guide lines on the left make the hierarchy visible while you build.
You can export the finished map in two text formats. Markdown bullets indent two spaces per level (great for Notion, Obsidian, or any markdown editor that supports nested lists). ASCII tree uses └── and ├── connectors plus │ guides, which renders well in plain text files, terminal output, or code comments.
For example, start with the central topic "Launch plan", add child branches "Marketing", "Product", and "Support". Under Marketing add "Website copy" and "Email sequence"; under Product add "Final QA". Switch the format to Markdown and Generate Mind Map. The output reads:
- Launch plan - Marketing - Website copy - Email sequence - Product - Final QA - Support
That outline pastes straight into any markdown tool and renders as a proper nested list.
FAQ
- How deep can the tree go?
- There is no hard depth limit — keep clicking + to nest further. In practice 3–5 levels is comfortable to read; beyond that, consider splitting into multiple maps.
- What is the difference between the two output formats?
- Markdown bullets indent two spaces per level and render as a nested list in any Markdown viewer. ASCII tree uses └──, ├──, and │ characters to draw the tree visually in plain text — great for README files or terminal output.
- Can I save and reload a mind map?
- Not directly — the tree lives in browser state. Export the Markdown or ASCII output, save it as a file, and paste it back in next time you want a starting point (or rebuild from the outline by reading down the indents).
- What happens if I delete the central topic?
- You cannot — the root has no × button. You can rename it, add children to it, and reset the whole tree, but the root always stays so the tree has somewhere to grow from.
- Does it use any network requests?
- No. Editing and exporting are pure client-side React. Refreshing the page resets the tree.
