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.
