How it works
Brain takes the documents you already have and turns them into a spatial map you can navigate, so structure stops living inside a wall of text.
1
Upload a file — PDF, DOCX, TXT, EPUB, slides or spreadsheets. The file is opened and read on your device; it is never uploaded to a server.
2
Brain extracts the structure — headings, topics and relationships become nodes in a 3D graph you can rotate, zoom and wander through.
3
Study and quiz yourself — generate questions from your own content (or write them yourself), then answer, self-grade and fill in the blanks.
4
Watch mastery spread — every node tracks your understanding and changes color from red to green, so weak areas glow before the exam does.
Fifteen minutes from upload to your first quiz – less time than you spent highlighting one page this week. And every step runs on your device: your files are never uploaded, so the map is yours alone.
