A mind map generator for your PDFs, notes, and slides
Upload a PDF, DOCX, PPTX, text file, or a photo of a page and get an editable mind map you can explore branch by branch.
Why a mind map helps with technical reference material
Developers who need a mind map generator API often want the same thing a student does: a way to turn long documentation into a structure they can scan at a glance. DeckOwl is a browser tool for that job. You upload your own material and get an editable, explorable map, which is useful for learning an unfamiliar API before you write code against it.
- Upload PDFs, DOCX, PPTX, plain notes, or photos of pages
- Get an editable map you can reorganize and rename
- Expand and collapse branches to study one section at a time
- Start free with 3 generations per month and no credit card
Works from your own files
Drop in PDFs, Word documents, slide decks, plain notes, or photos of pages. Photos are read with text recognition.
Editable structure
Rename branches, move ideas, and reorganize the map until it matches how you think about the material.
Explorable maps
Expand and collapse branches to focus on one section at a time instead of scanning a wall of text.
How it works
Upload your material
Add a PDF, DOCX, PPTX, notes file, or image. No credit card is needed to start.
Generate the mind map
DeckOwl pulls the main topics and subtopics from your content into a branching map.
Edit and explore
Adjust branches, then study by expanding each section. Turn the same material into flashcards or a quiz when you are ready.
Mind maps work well for APIs because the concepts nest naturally. Resources sit under endpoints, endpoints sit under HTTP methods, and each status code or error case hangs off the request that produces it. Seeing those relationships on one page makes gaps in your understanding easier to spot.
Once the map is built, you can keep working from it. Expand a branch to review one area, edit the map as your notes change, and reuse the same source to build a quiz or flashcard set for review.

Frequently asked questions
How many main branches should an API mind map have?
Aim for five to seven main branches, such as resources, HTTP methods, status codes, authentication, and payloads. Put specific endpoints and parameters under those branches so the top level stays readable.
How do I study API concepts from documentation?
Learn the core vocabulary first, then pair each HTTP method or status code with one example request and response. Redraw the map from memory a day later to check what you retained.
Is there a free plan?
Yes. The free plan includes 3 generations per month and studying in the browser, and you can start without a credit card. Exports are part of the paid plans.
What do I need to export a mind map?
Exports such as PDF, DOCX, Anki, and CSV are included with the Plus plan, which is $39 per year or $7.99 per month. Students can get 40 percent off with a school email.
