Here, we selected “judgment calls or personal styles” and chose a deeper explanation. It looks at why having room to use your own judgment matters to the author’s argument.
Learn more starts from a passage you select. Highlight the part you don’t follow and the explanation opens beside it, so you don’t leave the piece to go and look it up.

Common questions
What is Omphalis?
Omphalis is a reading app for the articles, papers, podcasts and videos you save because you want to understand them. Each one opens as a clean page built for reading, in type you can size and space to suit you: articles without ads or pop-ups, an episode or talk as a transcript with speakers and timestamps, and, during the trial or on a paid plan, a PDF's columns and footnotes in one reading order. A section map shows the shape of the piece, difficult terms and claims are explained beside the passage, and your highlights and notes stay where you made them. Away from the screen, you can listen instead.
What can I save to Omphalis?
Web articles and newsletters, PDFs, EPUBs and Word documents, podcast episodes and YouTube videos, plus your own notes and voice notes. Save a link from the browser extension or your phone's share sheet, upload a file, or subscribe to a feed, and what you keep sits together in one Library. On Free, a PDF is stored with its name and page count but not turned into a readable page; that takes the trial or a paid plan.
Where can I use Omphalis?
In any modern browser at app.omphalis.ai, and in the iPhone and Android apps, all sharing one Library. The Chrome and Firefox extensions bring the clean reading view and section map to the page you are on, and the Omphalis app in ChatGPT lets you read from your Library in a conversation. The web app is the most complete, and the phone apps let you download any item to read or listen offline.
Does Omphalis summarize what I save?
Pieces open with a short summary, there to help you decide where to begin, not to stand in for the source. The full text is still what you read, with explanations where it gets difficult and your own highlights on the passages that matter.
How do explanations work in the reader?
Some passages carry a dotted underline as you read: a term defined, a claim traced to its source, an idea expanded. Each explanation is written for its passage from the text around it, and many link to the paper, reference entry or saved item behind them. Open one and it appears beside the passage, so you stay in the piece. If something else stops you, select it and choose Learn more.
Can I ask questions about what I save?
Yes. Ask about the piece you are reading, a notebook of sources you have gathered, or your whole Library, then follow up. Every answer cites the passages it used, so you can follow any point back to the words it came from.
Do I need a credit card?
No. You can sign up, use the 30-day trial of every feature and stay on the free plan afterwards without ever entering a card. You add one only if you choose a paid plan.
Is there a free plan?
Yes, and it is not a trial: it stays free. Each month it includes an allowance for bringing in new sources and listening to them, and the pricing page shows how far that goes for each format. Reading what is already in your Library, writing notes and exporting everything never draw on it.
What happens when the trial ends?
Nothing is charged and nothing you saved is lost. After 30 days the account moves to the free plan, with your whole Library still readable and exportable. Features beyond Free, such as turning new PDFs into readable pages, come back whenever you choose a paid plan.
