A translation can be right in every word and still leave the listener lost. Smart Hints are the friend who leans over and explains: the verse the pastor quoted, the saying everybody local knows, the place nobody abroad has heard of. MulingStream was the first ever to build them, and nobody has built anything like them since. From September, the room and each listener choose what gets explained.
Every word was right, and they still did not understand it.
A pastor says "as the good Samaritan did", and a guest who grew up in another faith hears a correct sentence about a kind man from Samaria. A preacher in Denmark makes a joke about a Danish saying, the room laughs, and the translation is perfectly accurate and perfectly baffling. A speaker quotes John 3:16 by its reference alone, and the listener is told a book, a chapter and a number, without the words everybody else in the room already knows by heart.
This is the gap that word for word translation can never close, however good it gets. Translation carries the words. Understanding needs the background the words stand on.
Think of what happens when you visit a church abroad with a friend who lives there. Most of the service you simply follow. But now and then your friend leans over and whispers one sentence: "that is a verse from Luke, the parable of the man who helped a stranger", or "that saying means he is being modest". One sentence, at the right moment, and the whole passage makes sense.
Smart Hints are that friend. While the speaker talks and the translation flows, a short note appears on the listener's screen underneath the line it explains. The talk never stops for it. The listener reads it in a second and is back with the speaker, now understanding what the rest of the room understood.
When we started building live translation for churches, we kept hearing the same thing from guests: the translation was right, and they still missed the point, because a sermon is full of references the preacher never stops to explain. So on 19 March 2026 we released something new: hints that appear by themselves, in the listener's own language, at the moment they are needed.
We were the first to build this. Smart Hints were introduced for the first time ever by MulingStream: notes that explain the meaning behind the words while the speaker is still speaking, written for each listener in their own language. Nobody had built anything like it before. Carrying the words across is the ordinary part of translation. Explaining what they mean, live, was new, and it is the idea everything else in this post grew from.
A hint appears only when something would not travel on its own. Most sentences need nothing, and get nothing. When one does, the hint can explain:
Bible verses. When the speaker quotes or names a verse, the listener sees the reference with the book name used in their own language, and the verse itself from a widely used Bible translation in that language. The preacher says "John 3:16", and the guest reads the words. Sayings, idioms and wordplay. The proverb, the joke, the play on words that only works in the speaker's language, explained in one line. Measurements and money. Miles turned into kilometres, and a price shown in the local currency. Dates, calendars and times. A date in another calendar, a feast day, a time in another time zone. Places, people and customs. The town everybody in the room has visited, the name everyone knows, the tradition behind a word. Abbreviations, poems, hymns and quotations. The line from a hymn the congregation can sing from memory, and the guest has never heard.
For talks that go deep into a subject, the hints can go deeper too, at a basic, intermediate or advanced level: Christian theology, Jewish tradition and liturgy, migration and integration, and professional fields from finance and law to medicine and engineering.
There is nothing to prepare. No glossary to upload, no list of verses to send in advance, no extra person at the sound desk. Smart Hints follow the talk as it happens, so a pastor who departs from the notes to tell a story is followed just as well as one who reads every word.
Translation carries the words. Smart Hints carry what the words were doing.
Since 17 September 2026, Smart Hints are on by default in every room, included for everyone, and organised into categories that both the speaker and each listener control.
The speaker decides what the room explains. In the room settings, the speaker or the church's media team chooses which kinds of hints are on: Bible verses yes, money conversions no, theology at an advanced level for a Bible school, at a basic level for a Sunday with many guests. These choices are made before the talk begins, so nothing changes under the speaker's feet once they are live.
Each listener can overrule that for themselves. On their own phone, a listener sees every category the room allows, all switched on to begin with, and can switch off any of them, or switch hints off altogether. A guest who knows the Bible well can turn off the verse hints and keep the cultural ones. Someone who finds any note distracting can turn them all off and simply listen. Their choices are remembered on their phone for that room, so next Sunday it is already set the way they like it.
There is one rule that keeps this simple: a listener can narrow what the room allows, but never widen it. If the speaker has switched a category off, it does not appear for anyone. That way the church stays in charge of what is explained during its service, and every listener stays in charge of their own screen.
As of today, nobody else has ever built anything similar to Smart Hints. Seven months after we introduced them, MulingStream is still the only place where a listener gets the meaning behind the words explained live, in their own language, while the speaker is still speaking.
The quickest way to see Smart Hints is to hear a real talk with them. Open the listener demo room, pick a language, and watch the notes appear as the speaker goes. Or read more about the feature on the Smart Hints page.
We show you the whole thing live, in about fifteen minutes. Nothing is decided on the call and nothing follows it: you see it, and then you are the judge.
