The web app

# Read a source. Work out what you think.

Bring an article, PDF, podcast, or video into Omphalis. Open the text, get help with a difficult passage, and keep your own notes. The web app holds that reading and the work you build around it.

## Get help while the passage is still in front of you

In Chelsea Rosenthal’s Mattering That It’s You, an explanation opens over the phrase “little usually hinges”. Read it, compare it with the surrounding paragraph, and continue. You can highlight a passage, add a note, or choose Listen for natural-voice narration.

An explanation opens inside Rosenthal’s article, with actions to keep it, add a note, or put it in a notebook.

## Put your sources beside your own thinking

Make a notebook for a question you are working on. Add the relevant sources and write your own notes between them. You can keep an Ask answer there too, with citations to check when you return.
