Highlight a passage in a PDF, EPUB, video, audio file or web page, and it appears on your canvas as a node, linked to the exact place it came from.

There is nothing to set up. You read, you select a passage, you choose a colour — and the map builds itself.

For students, researchers, writers and teachers working with more sources than anyone can keep in their head.

READ EVERY FORMAT · Free
• Open PDFs, EPUBs, text files and imported web pages, as well as video and audio.
• Read continuously or page by page, with chapters and bookmarks.
• Every document reopens exactly where you left it.
• Documents live on your device.

ANNOTATE THE PAGE · Free
• Built-in OCR reads scanned books word by word in 12 languages, so a scan highlights like any PDF.
• Select an equation, handwritten or printed, and Nodebook renders it as LaTeX.
• Write, underline and draw on the page with a stylus, finger or mouse.
• Crop any part of a page — diagram, table, photo — and send it to the map.
• Insert a notepad mid-page: the PDF opens up for a comment that stays attached to that paragraph.
• Six highlight colours let you follow six separate threads.

BUILD THE MAP · Nodebook Plus
• An infinite canvas with no templates and no limit on nodes or depth.
• Drag a single node or a whole branch to reorganise your thinking.
• Drop one node onto another to merge them, and separate them later.
• Set snippets aside in the drawer, and keep a mini-map in view as you read.
• Export the map as a PDF or a FreeMind file, and the outline as a Word document.
• Back everything up into one .nodebook file and pick what to restore.

OUTLINE AND SEARCH · Nodebook Plus
• View the same map as a classic indented outline, and edit titles and text in it.
• Search the full text of every snippet, filter by tag or colour, and retag or recolour in bulk.

CONNECT YOUR NOTES · Nodebook Plus
• Create wiki-links between notes: start typing a title and Nodebook suggests matches.
• Click one and a preview shows you the target without losing your place.

REVISE WITH FLASHCARDS · Nodebook Plus
• Turn any snippet into a flashcard and review it with spaced repetition.
• Group cards by area, tag or source, or build your own sets.

WRITE YOUR OWN DOCUMENTS · Nodebook Plus
• A rich-text editor with headings, lists and quotations.
• Draw vector diagrams inside the text, erase single strokes and undo freely.

WORK TOGETHER · Nodebook Max
• Share a project as a viewer or an editor, and watch the other person's highlights appear live as you work.
• Send a file to another account with all your highlights and drawings intact.
• Every project keeps a version history with dates and authors, and restores to any point.
