Mind Map Maker

Turn a plain indented outline into a deterministic, downloadable SVG mind map entirely in the browser.

Privacy: your files never leave your device. All processing happens locally in your browser.

How to use

  1. 1.Enter a root line, then indent child lines with two spaces or one tab per level.
  2. 2.Select Generate mind map and inspect the parent-child connections in the local preview.
  3. 3.Download the standalone SVG and keep the outline if you want to edit the structure later.

About Mind Map Maker

Mind Map Maker converts a plain-text outline into a left-to-right SVG diagram without uploading the outline. The first nonempty line becomes the root. Two leading spaces or one tab create one nesting level, and each indented line connects to the nearest preceding node one level above it. Bullets using hyphen, asterisk, or plus are removed from labels after indentation is read.

The parser accepts up to 12,000 characters, 80 nonempty nodes, and 120 characters per label. The first node cannot be indented, indentation cannot skip a level, and a single indentation prefix cannot mix tabs and spaces. These rules make parent relationships deterministic and prevent a malformed outline from silently attaching to the wrong branch. Blank lines are ignored and line endings are normalized locally.

Each node receives a stable position based on depth and source order. Deeper nodes move right by a fixed column distance, rows follow the original outline order, and cubic SVG paths connect parent boxes to child boxes. The SVG canvas expands to include all generated nodes. This predictable layout favors readable outlines and testable output over automatic force-directed movement.

Every label is escaped for XML before it enters the SVG. Ampersands, angle brackets, quotes, and apostrophes therefore remain text instead of becoming markup. The downloaded file contains no scripts, foreignObject elements, external images, remote fonts, or network references. It is a standalone vector image with simple rectangles, paths, and text.

The preview and download are generated from a revocable local Blob URL. Editing the outline invalidates the previous result and releases its URL. The tool does not save projects, collaborate in real time, drag nodes, collapse branches, import proprietary mind-map formats, measure text wrapping, or guarantee that very long labels fit perfectly inside a box. Labels are intentionally capped, but concise phrases still produce the clearest diagram.

Use the result as a quick planning or communication artifact. For large knowledge graphs, freeform spatial editing, accessible semantic documents, or long-term collaborative projects, use a dedicated diagram application. Keep the original outline as the editable source because the exported SVG is a presentation artifact rather than a round-trip project file.

Methodology & sources

Normalize line endings, ignore blank lines, enforce bounded outline and label sizes, derive depth from tabs or pairs of spaces, reject mixed or skipped indentation, assign each node to the nearest prior parent at depth minus one, XML-escape every label, place nodes deterministically by depth and source order, draw parent-child cubic paths, and create a standalone SVG Blob with no scripts or external resources.

Frequently asked questions

Is my outline uploaded?
No. Parsing, layout, SVG generation, preview, and download all happen in the current browser tab.
How do I create nested branches?
Use two spaces or one tab for each level. Do not mix tabs and spaces within the same indentation prefix.
Can labels contain HTML-like text?
Yes. XML-sensitive characters are escaped and rendered as text, not executed as markup.
Can I drag nodes or reopen the SVG as a project?
No. This is a deterministic outline-to-SVG generator, not a persistent visual editor.
