About Patmos
Why Patmos exists
Patmos is for people who read the Bible every day and want to understand it better.
The mission
Depth for the Bible you already read
Most Christians never get to ask a Greek scholar what a word meant, or a historian what the first readers would have heard. Seminary students get that every week. Patmos puts that kind of help next to your Bible.
You open the Book you already read, and John meets you at the page with the original languages and the history behind the text. Then he sends you back to your church knowing more than when you started.
Patmos turns the open Bible on your desk into a seminary classroom.
The name
Why it’s called Patmos
Patmos is the island where the Apostle John received the Revelation (Revelation 1:9). John, the study companion, is named in honor of the Apostle, the beloved disciple who laid his head on Christ’s chest and stood at the foot of the cross. The Apostle’s love of Scripture shapes the spirit John studies in.
John isn’t the Apostle, and he isn’t claiming to be.
About John
John is a tool
John is an AI Bible study companion, powered by Claude, an AI model built by Anthropic. He’s been given deep grounding in the original Hebrew and Greek. He also carries cross-references across the canon, 2,000 years of Christian commentary, and a study framework rooted in historic Christian orthodoxy.
He’s been built with care, but he isn’t inspired. He can be wrong. He can miss things. He is not the Holy Spirit and cannot do what the Spirit does. He exists to help you encounter God’s Word more deeply, never to speak in God’s place. The theology page says where Patmos stands.
How a study goes
Five steps for a full study
A quick question gets a quick answer. When you sit down with a whole passage, John’s study follows a five-step pattern, and he adapts it to how deep you want to go.
1.Pray
A short prayer as you begin.
2.Preview
Where the passage sits in its book, and who wrote it, to whom and why.
3.Probe
The original languages, the cross-references and the history.
4.Personalize
What the passage calls you to believe, trust or obey.
5.Practice
One concrete step you can take today.
What Patmos doesn’t replace
Your Bible, your pastor, your church
Patmos isn’t a replacement for Scripture or for pastoral care. It isn’t a replacement for the sacraments or for the community of the Church.
Your Bible is the authoritative text. Your pastor, priest, or elder is the shepherd God has given you. Your church is the body in which you grow. Patmos is meant to serve those things and never to substitute for them.
If you ever find yourself studying with John instead of opening your Bible, close the app.
The same goes if you’re here instead of going to church or talking to a trusted believer in your life. Do those things first. John will be here when you get back.
What it’s built on
The pieces behind John
John’s answers come from Claude, made by Anthropic. When you photograph a page, Google’s Gemini reads it so Patmos can find the passage.
The Greek and Hebrew lexicons and word data come from STEPBible, based on work at Tyndale House, Cambridge, adapted for Patmos and used under the CC BY 4.0 license. The source data lives at github.com/STEPBible/STEPBible-Data.
