You can even chat with an uploaded PDF and ask questions about it, not just map it. - Create a mind map from PDFs, text, and more Upload PDFs, documents, images, audio, video, Markdown, or CSV files and turn them into editable mind maps. Advanced document analysis lets you work through long files and compare multiple sources in one map. - Summarize long content into a map The built-in AI summarizer pulls the key points out of dense material, the PDF summarizer condenses reports and research papers, and the text summarizer turns long notes and articles into clear takeaways, each one laid out as a map you can expand, focus, or edit. - A study and note-taking app, made visual Turn class notes, readings, and lectures into a visual study map.
