Turn any topic, PDF, or video into an AI mind map, free
Reviewed by The Desk · Last verified July 2026
“A refreshingly no-nonsense free tool that nails one job: turning a topic, PDF, or YouTube video into a structured mind map in seconds. It won't replace a full editing suite, but as an AI-first thinking and summarizing aid that's also open-source and self-hostable, it punches well above its (zero) price.”
Skip it ifSkip it if you need a polished, collaborative mind-map editor with real-time team editing, deep manual formatting, templates, and native desktop/mobile apps — this is a lightweight, AI-first web generator, not an XMind or MindMeister replacement.
What it is
Mind Map Wizard is a free, open-source web tool that generates hierarchical mind maps from a prompt, an uploaded PDF, or a YouTube video. Instead of starting from a blank canvas, you describe a topic (or hand it a document) and an LLM drafts a branching overview you can explore, edit, and export. It runs entirely in the browser with no signup and no ads, and keeps your data local.
Under the hood it routes generation through OpenRouter, and you can plug in your own API key for more privacy and control over which model runs. An AI assistant lets you refine the result — adding branches, reworking sections, or changing the look — and finished maps export to JPG, PDF, SVG, or Markdown. The codebase, including a custom rendering engine, is on GitHub under independent maintainer Linus Sch, so it can be self-hosted or extended.
It fits best as a fast thinking and summarizing aid for students, researchers, and solo makers who want a quick structured overview of a subject. It is not a full mind-mapping suite: manual editing depth, templates, and real-time collaboration are limited, and output quality tracks the underlying model. For zero cost and near-zero friction, though, it is a genuinely useful way to externalize and organize ideas.

Pros & cons
The good
- Genuinely free and open-source, with no signup, no ads, and a bring-your-own-key option for privacy
- Accepts text, PDFs, and YouTube videos, so it doubles as a fast summarizer rather than just a blank canvas
- Instant, clean output with export to JPG, PDF, SVG, and Markdown
The catch
- AI-generated maps are broad but can be shallow, and quality depends on the OpenRouter model you route to
- Manual editing and styling are limited next to dedicated suites like XMind or MindMeister
- No real-time collaboration or account-based workspace, so it is really built for solo use

Questions people ask
Is Mind Map Wizard really free?
Yes. The hosted app at mindmapwizard.com is free with no signup and no ads, and the full source code is open on GitHub for self-hosting.
What inputs can it turn into a mind map?
A text topic or prompt, an uploaded PDF, or a YouTube video URL. You can then edit branches with an AI assistant and export to JPG, PDF, SVG, or Markdown.
Which AI model does it use?
It routes generation through OpenRouter. You can also supply your own OpenRouter API key for more privacy and control over which model runs.
Does it support real-time team collaboration?
No. It is built for individual use with sharing and export rather than live multi-user editing, so it is not a replacement for team suites like MindMeister or Miro.
