What This Tool Does #

The Nodekit Embeddable Mind Map Generator is a lightweight widget you can add to any website. Your visitors type a topic. The widget generates a 3-branch visual mind map in seconds, directly on your page. No redirects. No popups. No signup required.

The widget is free to embed. Each instance includes a small "Powered by Nodekit" link, which is the only requirement.

How It Works #

Step 1: Copy the embed code #

Choose the embed format that fits your site (iframe or script tag), copy the code, and paste it into your HTML.

Step 2: Your visitors type a topic #

A text input appears on your page with a prompt like "Type a topic to generate a mind map." Your visitor enters any subject -- "content marketing strategy," "project risk assessment," "curriculum design for AP Biology."

Step 3: A mind map appears on your page #

Within seconds, the widget renders a 3-branch mind map with 2 sub-nodes per branch. Each node contains real, descriptive content -- not placeholder labels. The map is interactive: visitors can hover over nodes to read full content.

Step 4: Visitors explore the full version (optional) #

Clicking any node or the "Expand to full map" link opens the topic in Nodekit, where the visitor can generate a complete map with 5-6 branches and 20-35 nodes.

Sample Output #

Input: "Q3 marketing plan for a B2B SaaS startup"

Generated 3-branch map:

Every node contains specific, actionable content. Not "Marketing" and "Strategy" as labels. Real substance a reader can use immediately.

Embed Code #

Option 1: iframe (simplest -- works on any site) #

Copy and paste this into your HTML where you want the widget to appear.

<iframe
  src="https://nodekit.space/embed/mindmap-generator"
  width="100%"
  height="480"
  frameborder="0"
  style="border: 1px solid #e5e5e5; border-radius: 8px;"
  title="Free Mind Map Generator -- Powered by Nodekit"
  loading="lazy"
></iframe>
<p style="font-size: 12px; text-align: right; margin-top: 4px;">
  <a href="https://nodekit.space/free/embeddable-mindmap-generator?ref=widget" target="_blank" rel="noopener">
    Powered by Nodekit
  </a>
</p>

Option 2: Script tag (more control over styling) #

For developers who want to customize the widget appearance.

<div id="nodekit-mindmap-widget" data-theme="light" data-max-branches="3"></div>
<script src="https://nodekit.space/embed/widget.js" async></script>

Configuration options:

AttributeValuesDefaultDescription
`data-theme``light`, `dark`, `auto``light`Widget color theme
`data-max-branches``2`, `3``3`Maximum branches in generated map
`data-width`Any CSS value`100%`Widget width
`data-height`Any CSS value`480px`Widget height
`data-placeholder`Any string"Type a topic..."Input placeholder text

Option 3: React component (for React/Next.js sites) # 

npm install @nodekit/embed
import { MindMapWidget } from '@nodekit/embed';

export default function MyPage() {
  return (
    <MindMapWidget
      theme="light"
      maxBranches={3}
      placeholder="Enter any topic to generate a mind map"
    />
  );
}

Customization #

Themes #

The widget ships with three themes.

Light -- White background with dark text. Fits most sites.

Dark -- Dark background (#1A1A2E) with light text. Matches dark-mode sites and technical blogs.

Auto -- Detects the user's system preference and switches automatically.

Sizing #

The widget is responsive by default. Set a max-width on the container if you want to constrain it:

<div style="max-width: 640px; margin: 0 auto;">
  <!-- embed code here -->
</div>

The minimum recommended height is 400px. Below that, the mind map rendering becomes cramped.

Where to Use This Widget #

Productivity blogs. Add it to articles about brainstorming, project planning, or visual thinking. Readers can generate a mind map on the topic they are reading about, without leaving your page.

Education sites. Embed it in study guides or course pages. Students type their subject and get an instant visual overview.

Project management content. Add it to articles about project planning frameworks. Readers can generate a project plan mind map and see the structure immediately.

Resource pages. Include it on your "tools" or "resources" page alongside other free tools. The interactive element increases time on page and provides genuine value.

SaaS blogs. If you write about productivity tools, workflow optimization, or visual collaboration, the widget gives readers something to try instead of just reading about it.

Why We Built This #

Nodekit generates complete, content-rich mind maps from plain-text descriptions. That is the core product. The embeddable widget is a limited preview of that capability -- 3 branches instead of 5-6, shorter node content, no export options.

We built the widget because mind mapping is most convincing when you experience it. Reading about "AI-generated mind maps with real content in every node" is abstract. Typing "competitive analysis for a DTC skincare brand" and watching a structured map appear in seconds is concrete.

The widget is free because every embed puts a working product demo on someone else's website. If the output is good enough, the visitor clicks through to Nodekit. If it is not good enough, we need to improve the product, not restrict access to it.

Frequently Asked Questions #

Is the widget really free? #

Yes. No signup, no API key, no usage limits for the embedded widget. The only requirement is keeping the "Powered by Nodekit" attribution link visible.

Does the widget slow down my site? #

The widget loads asynchronously and does not block your page rendering. The iframe version is the lightest option. The script tag version loads approximately 45KB of JavaScript (gzipped). All mind map generation happens server-side, so the widget adds no CPU load to your visitors' browsers.

Can I remove the "Powered by Nodekit" branding? #

Not on the free version. The attribution link is the trade: you get a free interactive widget, and Nodekit gets a link. If you need a white-label version for enterprise use, contact us at hello@nodekit.space.

What topics can visitors generate mind maps for? #

Any topic. The AI generation handles business strategy, project management, marketing, education, technology, healthcare, finance, legal, and general knowledge topics. If the input is too vague (single word with no context), the widget will prompt the visitor to add more detail.

Is the generated content safe for my audience? #

The widget includes content filtering. Generated maps contain professional, informational content only. There are no ads in the widget output.

Does the widget work on mobile? #

Yes. The widget is responsive and adjusts its layout for smaller screens. On mobile, the mind map renders in a scrollable view with touch-friendly node interactions.

How do I track widget usage on my site? #

The widget fires a nodekit:generate custom event when a map is generated. You can listen for this event in your analytics:

document.addEventListener('nodekit:generate', function(e) {
  // e.detail.topic contains the topic entered
  // Track in your analytics platform
});

Can I pre-fill a topic? #

Yes. Add a data-topic attribute to auto-generate a specific map when the page loads:

<div id="nodekit-mindmap-widget" data-topic="content marketing strategy for B2B"></div>
<script src="https://nodekit.space/embed/widget.js" async></script>

Want Full Maps? #

The widget generates 3-branch maps with limited node depth. It is a preview.

Nodekit generates complete mind maps with 5-6 branches, 20-35 nodes of real content, and full export to PDF, PNG, and SVG. From a single sentence. In 15 seconds.

No credits. No blank canvas. No construction time.
