How it works

Convert a PDF to a mind map in 5 steps.

01

Open Marvex Studio

Go to marvex.app/app and click Convert a PDF to a mind map. No account required.

02

Drop your PDF

Drag any PDF onto the canvas, or click the upload button. The file stays on your device — Marvex Studio never uploads it to our servers.

03

Pick the AI engine

Choose Quick Outline (free, structural parse) or AI Analysis (uses your own Claude / OpenAI / Gemini API key for semantic mapping).

04

Watch the mind map appear

In 30–60 seconds the AI extracts every concept, theme, and relationship into an interactive mind map you can zoom, edit, and export.

05

Edit and export

Drag elements, add notes, link to source, and export as PDF, PNG, SVG, Markdown, or .mmap to share.

Why Marvex Studio

The fastest free AI mind map generator for PDFs.

AI mind map generator

Powered by your own Claude Sonnet 4.5, GPT-5, or Gemini 3 API key. We don't markup AI usage — you pay the provider directly.

Free PDF mind map

The free tier converts PDFs with Quick Outline at zero cost (3 maps × 30 elements each). Upgrade to Pro ($9–15/mo) for AI Analysis, unlimited maps, and the full export suite.

Mind map maker that respects privacy

Local-first storage. No accounts. No tracking. Your maps stay in your browser and filesystem unless you explicitly sync them.

Cross-platform mind mapping software

Use Marvex Studio on the web, or install the native desktop app for Mac (Apple Silicon + Intel), Windows (x64 + ARM64), and Linux (.AppImage / .deb / .rpm).

Concept map software for researchers

PDF reader, AI co-pilot, citation chips, side-by-side highlights, exportable summaries — built for people who actually read papers, not just file them.

Mind mapping for students

60-second study guides from any textbook PDF. Right-click any element to ask the AI for a deeper gloss, an example, or a counter-argument.

PDF to mind map · FAQ

Common questions.

Is the PDF to mind map converter free?+
Yes — the free tier converts PDFs using Quick Outline (no AI cost). For semantic AI mind maps, bring your own Claude / OpenAI / Gemini API key — we never charge you for AI usage. See the full breakdown on the pricing page or read the 5-step PDF-to-mind-map walkthrough.
Do I need to sign up to convert a PDF to a mind map?+
No. Marvex Studio is local-first — you can convert PDFs directly in your browser without an account, and your maps stay on your device. Open the studio or compare against Heptabase and Mapify which both require accounts.
How long does PDF to mind map conversion take?+
Typically 30–60 seconds for a 20-page paper. Larger documents or AI Analysis mode can take up to 2 minutes. The desktop app is noticeably faster on 100+ page PDFs because it skips the browser sandbox.
What's the difference between Marvex and other AI mind map generators?+
Marvex Studio is local-first (data never leaves your device by default) and uses Bring-Your-Own-Key AI — you pay your AI provider directly with no markup. Most alternatives lock you into their cloud and charge per generation. See the deep-dive comparisons: Marvex vs Mapify, Marvex vs Heptabase, and best PDF mind map tools in 2026.
Can I edit the mind map after the AI generates it?+
Absolutely. Every element, branch, and connector is fully editable. Drag, merge, split, rename, add notes, link to files, and export to PDF / PNG / SVG / Markdown / .mmap. The AI mind map generator explainer covers how to refactor an auto-generated map into something publication-ready.
Does Marvex Studio work offline?+
Yes. Open a previously-loaded mind map without an internet connection. AI Analysis requires connectivity (because it calls your AI provider's API), but Quick Outline and editing are fully offline. The Mac / Windows / Linux desktop app is the better choice if you spend most of your week offline.
Can I convert a scanned (image-based) PDF into a mind map?+
Yes, with one caveat. If your scanned PDF has an OCR text layer (most modern scans do), Marvex extracts text and builds the mind map normally. If it's a pure image scan with no text layer, run it through a free OCR tool first — Adobe Acrobat, Preview on macOS, or PDF24 online — then drop the OCR'd version into the studio. Native OCR ships in v0.3.
Is there a page or size limit for PDF mind mapping?+
Free tier: up to 25 pages per PDF and 30 elements per map. Pro Lite ($9/mo): up to 80 pages and 200 elements. Pro ($15/mo) and Lifetime: unlimited pages and elements. The desktop app handles PDFs up to 200 MB; the web app caps at 25 MB to keep parsing snappy.
What types of PDFs convert best into a mind map?+
Anything with a clear hierarchical structure — academic papers, textbook chapters, legal judgments, white papers, technical documentation, and meeting minutes. Quick Outline excels at these because it follows the heading tree directly. For dense prose with no headings (interview transcripts, novels), AI Analysis works better because it infers structure semantically. The mind mapping for students guide walks through the exact settings to use on academic papers.
Do I need to upload my PDF to the cloud to convert it?+
No. The PDF stays on your device throughout. Quick Outline runs entirely in your browser. AI Analysis sends the extracted text to your AI provider (OpenAI / Anthropic / Google) using your own API key — Marvex servers never see the file or the AI request. Read the full privacy policy and the BYOK explainer in the FAQ.
Can I convert a textbook into a study mind map?+
Yes — that's one of the most popular workflows. Drop a textbook PDF in, pick AI Analysis with Claude Sonnet 4.5 or GPT-4o, and within 60–120 seconds you get a chapter-by-chapter map with key concepts, definitions, and relationships extracted. Right-click any element to ask the AI for examples, simpler explanations, or counter-arguments. Teachers should also see the free "Teaching with Mind Maps" mini-course.
