What is Omphalis?
Omphalis helps you understand what you read and watch by placing explanations next to difficult passages, answering questions across your sources and tying notes to the original text. It suits students, researchers and heavy readers.
You subscribe to or upload sources, and the reader adds annotations that define terms, cite sources or expand on a point, with narration available as generated audio. Each source can be saved at different levels of detail and the library can be exported at any time.
Paid plans add key-moment recaps, a Discover search inside your library, voice conversations with your sources and the option to build a course from a document. Omphalis can also be used inside ChatGPT.
