What this mind map app can and cannot help with

A person typing this query is usually trying to reach one particular teacher, and DeckOwl cannot help with that. It is a mind map app that turns your own notes into an editable, explorable map, and it has no connection to any individual tutor, so no personal contact number is listed anywhere in the product.

Lets you edit every branch so the map reflects your course
Shows relationships between concepts across a whole chapter
Does not store or share contact details for teachers or tutors

Generate the full set

Editable branches

Rename, move, add, or remove any node so the map matches how your class organized the material.

Explorable structure

Expand and collapse branches to focus on one topic at a time instead of scanning a long page of notes.

Works with your files

Start from a PDF, Word or PowerPoint file, plain text, or a photo of a textbook page read with text recognition.

How it works

Upload your notes

Add the file or paste the text from the chapter, lecture, or handout you need to organize.

Review the branches

Check the main ideas and sub-points, then edit anything that does not match what your teacher covered.

Study the map

Explore the map in your browser on the free plan, or move on to flashcards and quizzes from the same material.

Where it does help is making sense of a dense chapter. Upload a PDF, DOCX, PPTX, plain notes, or a photo of a page, and the main ideas appear as branches you can rename, rearrange, and expand. The map shows how concepts relate, which is often easier to review than a flat list of notes.

If your teacher or coaching center has already shared materials, upload them and build a map for each topic. The free plan includes three generations a month with study in the browser, and the Plus plan adds unlimited generations and file exports.

Frequently asked questions

How many branches should a mind map for a biology chapter have?

Five to eight main branches usually works well for one chapter, with two to four sub-points under each. If a branch gets crowded, split it into its own map.

What is the best way to study from a mind map?

Close the map and redraw it from memory, then compare it with the original to find gaps. Quiz yourself on each branch by explaining it out loud in your own words.

Can DeckOwl find a specific tutor's phone number?

No. DeckOwl is not connected to any teacher or tutor and does not hold contact directories. It only creates mind maps from the material you upload.

Is exporting my mind map or study material free?

The free plan lets you study in the browser without exports. File exports such as PDF and DOCX are part of the paid Plus plan, which is $39 a year or $7.99 a month.
