On a Sunday morning in a church in Denmark, my wife could not follow the translation, and she switched it off. That was the moment the idea of MulingStream came to me, and the moment Mulingai really began. From our journal, published the day our site opened.
From our journal, written by our founder, David Christensen. We published it on 24 September 2025, the day mulingai.com opened for early access. The date in it is the day it happened.
Sunday 11 August 2024 began like most Sundays. We went to church, we greeted the people we see every week, and we sat down for the service in a church in Denmark.
My wife's heart language is Persian. Danish is not, and an hour of preaching in Danish is a long hour to follow. So the church did what many churches do for the people in the room who need another language: there was a Persian interpreter feed she could listen to.
That Sunday the translation could not keep up. It lagged behind the preacher, and it missed too much. Sentences arrived late, some never arrived at all, and the parts that did arrive did not always fit together. She tried to follow it, and then she switched it off.
She did not complain. She simply sat there for the rest of the sermon, in a service she had come to with her whole heart, unable to follow the message.
I could not stop thinking about it. Here was someone who loves the Lord, sitting in His house, missing His Word because of a language. And she was not the only one. In that room, and in churches everywhere, there are people who come faithfully every week and catch only part of what is said. Most of them never complain either. They just quietly receive less.
She came to hear the Word, and the language stood in the way.
That was the moment the idea of MulingStream came to my mind.
What if everyone in the room could hear the whole message, live, in their own language, on the phone already in their pocket? Not a summary afterwards, not a version that arrives late and broken, but the sermon itself, as it is preached, faithful to what the preacher means and not only to the words he uses. No headset to hand out at the door, nobody marked out as the person who needs help, and nothing the church has to set up beyond pressing start.
I am a software developer, and I knew enough to know it was possible, and enough to know it would be hard. Translating a sermon well is not translating a news report. A sermon is full of Scripture, names, sayings and stories, and every one of them has to arrive meaning what it meant.
For the next weeks the idea would not leave me. The more I thought about it, the clearer it became that this was not only her problem. It is the problem of every church with a guest who speaks another language, and of every person who has ever sat in a room and not understood what was being said.
On 3 October 2024 I wrote the first line of code. That story, and how the project got its name, is in 3 October 2024: the first line of code.
"Go into all the world and preach the gospel to every creature." (Mark 16:15)
Everything we have built since that Sunday comes back to it. MulingStream exists so that nobody has to switch the translation off and sit through a sermon they cannot follow. Every guest, every member, every person in the room should hear the whole message, in the language of their heart.
It started with my wife, in one church, on one Sunday. We pray it reaches every church that has someone waiting to understand.
MulingStream carries one speaker's words to every listener in the room, each in their own language, live.
