Why build it from your own slides

Lecture decks often pack a whole unit into forty slides, with the key ideas scattered across bullets, diagrams, and side comments. A PowerPoint concept map pulls those pieces into one view so you can see what connects to what before the exam.

Works with PPTX, PDF, DOCX, plain text, and photos of slides read with text recognition
Keeps branches tied to your course's own terms instead of a generic template
Lets you rename, rearrange, and prune nodes as you learn the material
Pairs with flashcards and quizzes made from the same deck

Example fractions and decimals mind map branches

Equivalent fractionsMultiply numerator and denominator by the same number · Simplify by dividing both by the greatest common factor · Cross-multiply to test whether two fractions are equal

Converting decimals to fractionsWrite the decimal over a power of ten · Reduce to lowest terms · Read the place value, such as tenths, hundredths, or thousandths

Adding and subtracting decimalsLine up the decimal points · Pad with zeros so both numbers have the same number of places · Add or subtract as whole numbers, then place the decimal point

Multiplying fractionsMultiply the numerators · Multiply the denominators · Simplify before multiplying when a numerator and denominator share a factor

Dividing fractionsMultiply by the reciprocal of the second fraction · Flip only the divisor, not the first fraction · Check that the answer is reasonable in size

Generate the full set

Reads your slides

Upload a PPTX and the text from your bullets, titles, and speaker-note-style summaries is pulled into one structure.

Editable branches

Rename, move, or delete any node so the map matches how your instructor framed the topic, not a generic template.

Explore at your pace

Expand and collapse branches to focus on one idea at a time, then turn the same material into flashcards or a quiz.

How it works

Upload your deck

Add a PowerPoint file, or paste lecture notes, a PDF, or a photo of a printed slide.

Let the AI map the ideas

DeckOwl groups related points under main branches and shows how the ideas link together.

Edit and study

Adjust the map to fit your course, then explore it in the browser or use it as the base for review.

A generic printable map may not match what your professor emphasized. Generating the map from your own deck keeps the branches tied to your course terms, examples, and order of topics.

Once the structure is right, you can check each branch against the slides and fill gaps from your notes. The map stays editable, so it can grow as the course moves on.

Frequently asked questions

How do I connect fractions and decimals in a concept map?

Start with the central idea, then link equivalent forms such as 1/4 and 0.25 under the same branch. Add operations as sub-branches so each rule stays attached to the number type it applies to.

How many branches should a study concept map have?

Most useful maps have about five to seven main branches, with two to four sub-points under each. If a map grows wider than that, add a second level instead of more main branches.

Does DeckOwl accept PowerPoint files?

Yes, PPTX files can be uploaded alongside PDF, DOCX, plain text notes, and photos of pages. Photos are read with text recognition.

Is there a free plan?

Yes, the free plan includes 3 generations per month and studying in the browser. Exports such as PDF, DOCX, Anki, and CSV are paid features on the Plus plan.
