Flashcards are good at facts and bad at showing you how the facts connect. Exam questions are usually testing the connection.
Studyflash builds an interactive map from any deck: the central theme, branching into topics, subtopics and detail. Zoom and pan, expand the branch you are unsure about, collapse the parts you already know.
Every concept links back to its cards
Click a concept and you get an explanation panel with a link to the flashcards it came from. That is the part other mind map tools do not do, and it changes what the map is for. It is not a picture of your material, it is a way into it: find the branch you cannot explain out loud, click it, study those cards.
Right-click to colour-group themes, so the structure on screen matches the way you have organised the subject in your head.
When it helps
At the start of a topic, to get the shape before the detail. At the end of one, to check the structure holds without looking at anything. Before an exam covering several weeks, to find where the topics meet, which is usually where the harder questions come from.
Questions and answers
Any deck, whichever way the material got in: an upload, a recorded lecture, or an Anki import.
You can expand, collapse and colour-group nodes.
Yes, and that is the point of it. Every concept links back to the cards behind it.
