Turn your notes into an editable cogniguide AI mind map
Upload a PDF, DOCX, PPTX, or photo of a page and get a mind map you can edit and explore branch by branch.
How an AI mind map helps you study a dense chapter
A long reading often hides its structure, and students who memorize it line by line tend to forget how the ideas connect. A cogniguide AI mind map generator starts from the document itself, pulling out the main ideas and grouping their supporting details so you can see the layout before you memorize any of it.
- Works from PDF, DOCX, PPTX, plain text, and photos of pages
- Every branch stays editable, so the map follows your course
- Expand and collapse sections to study one idea at a time
- Free plan allows 3 generations per month and browser study
Built from your own files
Add a PDF, DOCX, PPTX, plain text, or a photo of a page. Text recognition reads the images so the map reflects your actual material.
Editable branches
Rename, move, or delete any branch. Adjust the map until it matches how your course organizes the topic.
Explore at your own pace
Expand and collapse sections to focus on one idea at a time, then turn the same material into flashcards or a quiz.
How it works
Upload your material
Drop in lecture slides, a textbook chapter, or typed notes. No credit card is needed to start.
Review the generated map
DeckOwl proposes main branches and sub-points. Check that the structure matches the source.
Edit and explore
Reshape the map, collapse branches you know, and expand the ones that still feel fuzzy.
Editing matters as much as generating. A map built from your own lecture notes will reflect the emphasis your instructor gave, and you can rename or regroup branches until the structure matches the exam outline. Collapsing a branch hides what you already know, so review time goes to the gaps.
Once the map is right, use it as a study tool rather than a poster. Cover a branch and try to recall its sub-points, then open it to check. This retrieval step is what turns a tidy diagram into knowledge you can use on a test.

Frequently asked questions
How many branches should a mind map have for one chapter?
Most chapters work well with 5 to 8 main branches, each holding 3 to 5 supporting points. Fewer branches usually means the map is too general to review from.
How can I tell whether my mind map will help me study?
Each branch should read as a short phrase you can explain without looking. Redraw or recall the map from memory a day later to see what you kept.
Is DeckOwl the same as CogniGuide?
No. DeckOwl is a separate product that builds mind maps only from the PDFs, notes, and images you upload.
Can I export my mind map?
The free plan lets you study in the browser without exports. Plus, at $39/year or $7.99/month, adds PDF, DOCX, Anki, and CSV export.
