Need a mind map app offline? Turn your notes into one here
DeckOwl builds editable mind maps from your PDFs, slides, and notes with AI. It runs in the browser, so plan on an internet connection when you generate.
What a mind map app offline can and cannot do here
Some students want a mind map app offline so they can sketch ideas on a train or in a lab with no signal. DeckOwl works differently: it runs in your browser and uses AI to build maps from the material you upload. Once a map exists, you can edit and explore it on screen.
- Free plan: 3 generations per month and study in the browser.
- Plus: unlimited generations plus PDF, DOCX, Anki, and CSV export.
- Pro: stronger AI model, bulk upload, and QTI 2.1 and Moodle XML export.
- Students get 40% off with a school email, and no credit card is needed to start.
Maps from your own files
Upload a PDF, DOCX, PPTX, plain text, or a photo of a page and get a mind map built from that material.
Editable and explorable
Rearrange branches, expand sub-topics, and adjust the map as your understanding changes.
Pairs with other study modes
Turn the same notes into flashcards with spaced repetition or into quizzes with explanations.
How it works
Upload your notes
Add a file or paste text. Photos of pages are read with text recognition.
Generate the mind map
DeckOwl organizes the main ideas into branches and sub-points.
Edit and review
Change the layout, add detail, and study the map in your browser.
If offline access matters most, test the free plan first to see whether browser study fits your routine. Plus adds PDF and DOCX export for your study material, so you keep copies outside the app.

Frequently asked questions
How do I make a mind map for studying biology?
Start with one chapter or lecture, then list the main topics as top-level branches. Add the key terms and processes under each branch, and keep each node short enough to recall.
What makes a good mind map for exam review?
Each branch should cover one concept you could be tested on. Test yourself by covering a branch and trying to rebuild its sub-points from memory before checking.
Can I use DeckOwl without an internet connection?
DeckOwl runs in the browser, so you will need a connection to generate new maps. The free plan lets you study in the browser without exports.
Are exports included in the free plan?
No. PDF, DOCX, Anki, and CSV export start on Plus, which costs $39/year or $7.99/month.
