135 COURSES BUILT · EVERY CLAIM SOURCED

We gather the evidence.
You do the thinking.

Ask anything about Scripture. Every answer traces to a named work — and when the sources are thin, we say so instead of inventing theology.

WHY TRUST AN AI WITH SCRIPTURE?

You shouldn't. That's the point.

Lumin doesn't generate theology — it retrieves it. Every claim carries a badge: verified means we hold the source text; trainingmeans it comes from the model's reading, clearly labeled. And when neither exists, you get our most important answer: “No strong answer — and we won't invent one.”

“The paidagōgos was not a teacher but a custodian — a household slave who walked the child to school and kept him out of trouble.”

“Will my dog be in heaven?” → No strong answer. We searched 1,480 works — and suggested talking to your pastor.
HOW IT WORKS · 0:54

A question that won't let go becomes a course.

01
Ask
Get an answer built from real, named sources — with the disagreements left in, not smoothed over.
02
Pull the thread
Follow-ups stay in one thread. Attach a PDF, a photo of a page, or paste a wall of text — Lumin reads it all.
03
Grow a course
One tap turns the thread into a structured course — chapters, key terms, flashcards at the end of every lesson.
THE READER

Lessons that read like a beautiful book, not a chatbot.

§-numbered sections, original-language key terms, sources that disagree on the same page, and discovery questions that make you do the thinking. Each chapter ends with a minute of flashcards — spaced, not nagging.

THE QUIET NOTEBOOK
Clip anything. It lands as a quote, not a widget.

One click sends a verse, a quote, or a whole paragraph into your open note — an italic line with a source, like a real notebook. Need evidence for your own writing? Select it and ask. Nothing else is on the page.

“Where you go I will go, and where you stay I will stay.”
RUTH 1:16 · CLIPPED FROM CH. 5
DAILY VERSE
One verse a day — with trivia worth repeating.

Not a guilt streak. A verse, a “did you know,” and one fact you'll tell someone at dinner. Favorites become flashcards.

DID YOU KNOW
The Hebrew for “declare” in Psalm 19 is a continuous participle — the heavens are declaring right now, without pause.
WHO IT'S FOR

Built for how you actually study.

Pastors
“Saturday night, three commentaries open, no time.”
Sermon prep with traceable sources — clip straight into your draft. Monday tells you who in your flock needs a call.

Students & seminarians
“I need sources I can actually footnote.”
Original-language terms, sources that disagree on the same page, and a citation trail on every claim — built for papers, not vibes.

“Is this a dumb question?”
No question is. Ask at your own level, get a daily verse with trivia worth sharing, and grow a course from whatever won’t let you go.

“Ten people, ten different starting points.”
Put everyone on a pathway — ordered courses with your pacing. Share this week’s study, see who’s stuck (never what they asked), and announce once instead of ten texts.

Looking for a “Bible chat app”?
“I tried one. It made things up.”
This is the one that doesn’t. Every answer is retrieved from real works and badged — and when the sources are thin, Lumin says “no strong answer” instead of improvising doctrine.

FOR CHURCHES

A shepherd's tool, not an analytics dashboard.

The Pastor's Desk opens with a Monday briefing in plain language — who needs your hand, what Sunday needs, how the flock is moving. Members never see analytics, and never pay.

MONDAY BRIEFING · APR 21
“A heavier week, Sarah — grief questions tripledand two people went quiet. Meanwhile, Romans is quietly becoming your church's book.”
AP
Ana went quiet after a 41-day streak.Write to Ana
Privacy is the covenant

Leaders see themes, never questions— “grief is rising,” not who asked what. Members opt in, trends need 3+ participants, and the disclosure is written where everyone can read it.
