Theo is a Bible study AI: a research, learning, and interpretation tool for Scripture, theology, and history — built for the people ChatGPT lets down with its Unitarian bias. Your notes are Theo's memories. As you grow in your walk, your Theo grows. As you learn, your Theo learns. Most AI tools play it safe. They won't affirm Jesus. They flatten every faith into "all paths lead to God." They give you Wikipedia when you're asking the questions that matter. Theo doesn't. Theo believes Jesus Christ was who he claimed to be: that he died, rose from the dead, and is Lord. From there, Theo helps you research, study, wrestle, and see the world through the lens of Christ. Whether you've followed Christ for forty years or you're an atheist honestly examining the evidence for the first time, Theo meets you where you are — with real answers and real evidence, not pleasantries. WHO IT'S FOR • Christians who want a serious study and research partner that won't water down the faith • Atheists and agnostics taking an honest look at Christianity, the historical Jesus, and the case for the resurrection • Seekers tired of AI that treats every religion as equally true • Anyone who wants Scripture, theology, and Church history at their fingertips • Anyone who wants to read the world and the news through a Christian lens WHAT THEO DOES • SCRIPTURE, PROPERLY: verses come with the original Greek (or the Hebrew and Septuagint for the Old Testament), the cultural context they were written into, and a clear read on how they land today • SCRIPTURE INTERPRETS SCRIPTURE: Theo traces the canon's own threads — the clear passage governing the obscure one — instead of proof-texting • A CURATED KNOWLEDGEBASE: theology, apologetics, the Church Fathers, and reasoned answers to the hard questions • A CHRISTIAN LENS ON THE WORLD: live web search for the news, culture, and current scholarship — read today through Christ • NOTES THAT REMEMBER: write down what you're learning and praying about; Theo recalls it and grows with your walk • CHAT THAT GOES SOMEWHERE: Theo can recall past conversations, so the study builds instead of restarting WHAT MAKES THEO DIFFERENT • AFFIRMS CHRIST: not Unitarian, not neutral, not afraid of its beliefs • ANSWERS WITH CONVICTION: Theo lands answers and shows the reasoning — and tells you plainly which parts are settled, which are inference, and which are honest open questions • ANTI-SCHISM: not locked to one denomination; respects yours and meets you in it • HEART-FIRST: Jesus cared about the heart, not the performance. Theo asks the question underneath the question. A NOTE ON HARD MOMENTS Theo is not a crisis service. If you are in danger, planning self-harm, or facing an emergency, Theo will tell you to reach a human: 988, 911, or someone you trust today. OPEN TO ALL Theo is built for Christians, but you don't have to believe anything to start. Bring your doubts, your questions, your curiosity. The texts are waiting. The reasoning is solid. And Theo is right here. Download Theo and start studying. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Postil connects the Bible to everything being taught, written, and said about it — so Scripture never dead-ends at the page. Tap any verse and you'll see the sermons, articles, podcasts, and cross-references that actually unpack it. Alongside a full Bible reader — six translations including KJV and WEB, cross-references on every verse, a built-in Strong's dictionary for word study, adjustable text size, light and dark modes, and search across every book, chapter, and verse — Postil gives you a curated feed of Christian content from creators, ministries, and news sources worth trusting. No algorithm chasing outrage, no noise. Most Bible apps stop at the text. Most news apps chase engagement. Postil tries to do neither: it's one place to read Scripture, find commentary worth your time, and follow the people actually shaping Christian thought right now. The feed pulls from vetted creators and ministries across articles, podcasts, videos, and news — sortable by Hot, New, or Top, filterable by type. Postil Partners are creators who've linked an account with Postil; follow them and their content gets priority placement in your feed. Save anything to come back to later, and follow the sources you trust most. Browse by what you're actually curious about — Bible & Scripture, Theology & Doctrine, Spiritual Formation, Church & Ministry, Christian History, Life & Culture, Apologetics & Culture, Current Events & Ethics, Missions & Evangelism, and Interviews & Conversations. Every piece of content has real discussion under it, not a comment section left to rot: comment, "upcross" what resonates, and use real moderation tools — block, report, hide — when something needs it. Pick an avatar from the built-in set to represent yourself. Stay in the loop with notifications when someone replies to you or a creator you follow posts something new. Listen to podcasts in the background with full lock-screen and Control Center controls, and keep articles, videos, podcasts, and their comments together in one reader instead of bouncing between apps. Postil Pro removes ads from your feed and Bible verse content cards. (Video, podcast, news, and article ads come from third-party embeds outside Postil Pro's scope, so those aren't affected.) Whether you're studying a passage closely, catching up on Christian news, or looking for a podcast willing to engage hard questions, Postil brings it into one trustworthy, distraction-free feed.
