About

Nodebook

Read full description

Nodebook combines a document reader with an infinite mind map. 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 β€” 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 Β· Free β€’ Open PDFs, EPUBs, text files and imported web pages, as well as video and audio. β€’ Read continuously or page by page, with chapters and bookmarks. β€’ Every document reopens exactly where you left it. β€’ Documents live on your device. ANNOTATE THE PAGE Β· Free β€’ Built-in OCR reads scanned books word by word in 12 languages, so a scan highlights like any PDF. β€’ Select an equation, handwritten or printed, and Nodebook renders it as LaTeX. β€’ Write, underline and draw on the page with a stylus, finger or mouse. β€’ Crop any part of a page β€” diagram, table, photo β€” and send it to the map. β€’ Insert a notepad mid-page: the PDF opens up for a comment that stays attached to that paragraph. β€’ Six highlight colours let you follow six separate threads. BUILD THE MAP Β· Nodebook Plus β€’ An infinite canvas with no templates and no limit on nodes or depth. β€’ Drag a single node or a whole branch to reorganise your thinking. β€’ Drop one node onto another to merge them, and separate them later. β€’ Set snippets aside in the drawer, and keep a mini-map in view as you read. β€’ Export the map as a PDF or a FreeMind file, and the outline as a Word document. β€’ Back everything up into one .nodebook file and pick what to restore. OUTLINE AND SEARCH Β· Nodebook Plus β€’ View the same map as a classic indented outline, and edit titles and text in it. β€’ Search the full text of every snippet, filter by tag or colour, and retag or recolour in bulk. CONNECT YOUR NOTES Β· Nodebook Plus β€’ Create wiki-links between notes: start typing a title and Nodebook suggests matches. β€’ Click one and a preview shows you the target without losing your place. REVISE WITH FLASHCARDS Β· Nodebook Plus β€’ Turn any snippet into a flashcard and review it with spaced repetition. β€’ Group cards by area, tag or source, or build your own sets. WRITE YOUR OWN DOCUMENTS Β· Nodebook Plus β€’ A rich-text editor with headings, lists and quotations. β€’ Draw vector diagrams inside the text, erase single strokes and undo freely. WORK TOGETHER Β· Nodebook Max β€’ Share a project as a viewer or an editor, and watch the other person's highlights appear live as you work. β€’ Send a file to another account with all your highlights and drawings intact. β€’ Every project keeps a version history with dates and authors, and restores to any point. PLANS β€’ Nodebook is free to install, with the reader and its annotation tools included. β€’ Buy Nodebook Plus once β€” $39.99 β€” for full offline functionality, including mind maps creating and editing, flashcards and more. β€’ Subscribe to Nodebook Max for the cloud: sync across your devices, collaboration and version history. $8.99 a month, or $89.99 a year.
