Why Preaching Lab Exists
October 10, 2026 · written by the person who built it
I grew up in a pastor's home, hearing my father preach every Sunday.
When I left home to study, I sat under many other pastors. The same text could sound entirely different from one pulpit to the next.
Using AI as it improved month by month, I felt two things at once: concern, and hope.
I learned that many pastors already use AI when they prepare. But what happens when AI's share of sermon preparation grows too large? Even the people who build these systems call them black boxes — how they learned what they know is hard to verify. I worried that pastors and churches could end up led by something no one can fully see into.
So I set out to use what AI does well, wisely, on the pastor's side. That is how Preaching Lab began.
Preaching Lab does not write your sermons. Each week it transcribes the sermon you actually preached, using speech recognition, and keeps it — an archive that grows Sunday by Sunday. Then, from that record, it gives you feedback with the classic commentaries set alongside the text.
Three things we hold to
- We do not write new sermons for you. Even the manuscript we return is your own sermon, cleaned up, with suggested changes kept separate.
- We do not invent quotations. Commentary is quoted from the original and set beside your text.
- Only you see it. A report opens only under your account, and the sermons you send are not used to train AI.
