Omphalis vs Nodebook

Omphalis is a calm home for the things you want to understand, not just get through. Save an article, a podcast, a YouTube talk, a PDF, or a voice note. Every one of them becomes the same clean, readable page, with structure you can actually use. What you get on the very first item Clean reading. Articles arrive without banners, popups, or clutter. PDF layouts are untangled. Podcasts and videos are transcribed. One calm page, whatever the source. Strata. Each piece is broken into typed moments, as many as its length and density call for, so you can see the shape of something before you read it and go straight to the part you came for. Marks. Omphalis quietly underlines the few things worth a second look: a source worth checking, a term worth defining, a claim worth following up. Keep the ones that earn it, dismiss the rest. Listen. Any saved item can be read aloud in a voice you pick, with lock screen controls. What you get as your library grows Connections. Omphalis surfaces what your own library already knew: a piece that echoes something you saved months ago, a claim that sits against another, a bridge between two topics you never filed together. It is descriptive, not predictive. It shows you your library, not a feed. Today. A short daily loop with a clear place to start and a clear place to stop. How it is built Your own thinking and other people's work go through the same pipeline and connect to each other equally. There is no separate bucket for your notes. Omphalis is custodial software. There is no trending tab, no infinite scroll, and no streak to keep alive. Today finishes. Suggestions, not verdicts. The system that picks moments and marks is fallible, and the app is built to show you that rather than hide it. Every suggestion has a keep or a dismiss beside it, and Settings names the substrate plainly. Your library, your data Sign in with Apple or Google. Export or delete your account and its contents from inside the app, at any time. What you can do Omphalis lets you save, read, and listen across your Library, Inbox, and Today.

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 — 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. PLANS • Nodebook is free to install, with the reader and its annotation tools included. • Buy Nodebook Plus once — $39.99 — for full offline functionality, including mind maps creating and editing, flashcards and more. • Subscribe to Nodebook Max for the cloud: sync across your devices, collaboration and version history. $8.99 a month, or $89.99 a year.
