Immerse is a sacred-text reader built for research: read every tradition side by side, collect and annotate passages as you go, and turn them into organized, exportable compilations. It's an offline library of 400+ sacred texts — and a set of tools for building your own thematic compilations from across every tradition in it. BUILD COMPILATIONS Long-press any passage to select it, then add it to a compilation. Compilations are your collections: gather passages from the Qur'an, the Bible, the Upanishads, the Buddhist sutras, the Bahá'í writings and more under a single theme — Prayer, Justice, The Nature of the Soul. Your compilation grows one passage at a time, across every tradition in the library. ANNOTATE AS YOU READ Add notes to any selection. Create cross-references linking a passage in one book to a passage in another — the connections you notice, kept where you found them. When you build a cross-reference, tap Suggest a match to get AI-ranked related passages from across the whole library, each with a one-line reason. Everything anchors to the exact text you selected. EXPORT AND SHARE Export any compilation — or a set of cross-references, laid out side by side by tradition — as a Word document, PDF, spreadsheet, or Markdown file, complete with your notes. Or share your compilations or cross-references with a private link: anyone with the link can open them or save a copy into their own library. Ready to send, publish, or study from. A COMMUNITY OF READERS Make any compilation public and other readers can find it in Discover — preview its passages, then import the whole collection into your own library with one tap, and follow the readers whose work you want to keep up with. A living body of interfaith study, built by the people using it. THE LIBRARY 400+ complete sacred texts, all offline. Full-text search across every one of them at once — type a whole question and AI finds the passage that answers it, right alongside your keyword matches. Listen to any passage read aloud. Your reading position is saved automatically. Also available in Spanish, French, Persian, Chinese, Turkish, and Russian, with full right-to-left support for Persian.

This free library gives you their own words in fresh English translations, made from the original Greek and Latin. TODAY opens with a passage from the Fathers and the Bible verse behind it, the same one viapatrum.org shows that day. Tap to read the passage, see what the other Fathers said, or read the chapter. READ whole works, from Clement of Rome and Ignatius to Origen and beyond, in a clean reader built for long reading. The whole library downloads once and works offline. LISTEN with read-along audio. The sentence being read is highlighted, and playback continues with your screen locked. Narration is computer-generated. SCRIPTURE AT A TAP.

With a connection you can also read the NIV, NASB, NIrV, Amplified Bible, ASV and Geneva Bible. Browse any chapter to see which Fathers cite it. TOPICS gather what the Fathers taught on one question, earliest first. The TIMELINE shows who wrote when. SEARCH covers every work and topic. Free, with no account, no ads and no tracking.
