Sit with the great Christian minds. AdFontes.AI lets you put a question to Augustine, Aquinas, Calvin, Edwards, and dozens more — and read an answer grounded in what they actually wrote. Every response draws on a library of their own texts, with citations you can follow back to the source. Ad fontes: to the sources. THREE WAYS TO READ Chat — One-on-one with a single thinker. Ask about grace, suffering, prayer, the sacraments, doubt. Follow the thread as far as you want to take it. Panel — Convene up to three voices at once and put the same question to all of them. Listen to where they agree, and where they don't. Study — Move through Scripture passage by passage with the historical commentary drawn up alongside the text. GROUNDED, AND SHOWS ITS WORK The answers are not improvised. They are built from a searchable library of the thinkers' own writings, and where a claim rests on a specific passage the app shows you the citation. You are always one tap from the actual text. BUILT FOR READING Light, sepia, dark, and OLED themes. Adjustable type size. Portrait or landscape, on iPhone and iPad. Your conversations, bookmarks, and study sessions sync to your account, so the thread you started on your phone is waiting on the web. HONEST ABOUT WHAT IT IS These are AI representations of historical figures, built on their writings — not the figures themselves, and not a substitute for pastoral care, Scripture, or the church. Quotations are marked and cited. Everything else is the model's reconstruction, and worth reading the way you would read a well-informed study partner: engage it, and check it. FREE TO BEGIN Fourteen days of full access to every mode and every voice, no card required. After that, Chat stays free with a daily message allowance.

STAY PRESENT FOR THE SERMON Sunday Notes helps you follow the message live, see Bible references as they are mentioned, and return to the moments that mattered afterward. SEE SCRIPTURE AS IT IS PREACHED Start recording and follow the sermon through a live transcript. When Sunday Notes recognizes a Bible reference, it appears on screen for you to tap. Open the passage in the built-in KJV Bible, see the referenced verse highlighted, and return to the message without losing your place. HEAR THE MOMENT AGAIN Sunday Notes creates playable insight cards from meaningful sermon moments. Read the takeaway, play the corresponding sermon audio, and save or share the moment, not just a text quote. YOUR COMPLETE SERMON, ORGANIZED After the service, revisit: • The sermon recording and transcript • Bible references mentioned during the message • An AI-generated overview and key takeaways • Themes and practical applications • A concluding reflection and prayer • Playable, shareable insight cards • Your own timestamped notes BUILD YOUR SERMON ARCHIVE Search past sermons by title, transcript, Scripture or theme. Organize messages into folders, mark favorites, and return to important teachings throughout the week.
