A listener in the Vienna congregation following the German translation on their phone during a Sunday service.

In use every Sunday

Hear a service in a language you don't speak.

A real sermon on the love of Christ, then the same words in English, translated live and spoken in a natural voice that keeps the preacher's tone and rhythm, not as a subtitle.

  • 57 languages, by voice and caption availability
  • 0 apps for your congregation to install

Recorded at a teaching seminar in Thessaloniki and shared with the preacher's permission. The translation and the voice you hear it in are the live system.

Farsi, as preached

تا مسیح به واسطهٔ ایمان در دل‌های شما ساکن شود، و توانایی آن را بیابید که با تمام مقدسین به طول و عرض و عمق و ارتفاع محبت مسیح پی ببرید، و آن محبت را که فراتر از معرفت بشری است بشناسید، تا از همهٔ کمالات خدا آکنده شوید.

English, as the listener heard it

So that Christ may dwell in your hearts through faith, and you may be able to comprehend with all the saints what is the breadth and length and depth of Christ's love, and to know that love that surpasses knowledge, so that you may be filled with all the fullness of God.

Translation is the first minute. We built everything after it.

Live translation is becoming table stakes. Sanctavo is the whole journey: understand who you're reaching, welcome the person who walked in for the first time, keep every sermon, and speak to everyone in their own language. For years, not Sundays.

Live voiceLive

Your people listen to the preacher, not to a screen.

A natural translated voice in the listener's ear, under a second behind the speaker, captions alongside for those who prefer to read, right-to-left scripts included.

Elsewhere:read the subtitle, miss the moment.

Auto-polishSelf-correcting

Captions that fix themselves.

A rolling pass a few sentences behind live corrects obvious slips, repeats and punctuation in place, on screen and in the transcript. The correction process is designed to fix transcription errors without intentionally summarising, adding or reordering the speaker’s meaning.

Elsewhere:the slip stays on the screen.

First-time visitorsWelcomes

From anonymous listener to known visitor, by their choice.

A newcomer can tap “I'm new here”, leave a preferred language and a way to reach them, and receive today's message with a welcome. Follow-up runs from there, and you see who came back.

Elsewhere:a clipboard by the door.

Ask the SermonAnswers

Your people can ask the message a question.

Anyone who was there, or wasn't, asks in their own language and gets an answer grounded in what was actually said, with the place in the transcript it came from.

Elsewhere:a recording and a scrub bar.

Church MemoryLearns you

It learns how your church speaks.

Names, places, the terms you use and the way you use them: noticed service by service, approved by your team, carried into every translation and every draft after. Week ten sounds more like you than week one.

Elsewhere:every service starts from zero.

Sanctavo PressPublishes

A teaching series becomes a book.

Add the sessions: recordings, YouTube links, a Drive folder. Press proposes a chapter map, you confirm it, and it writes and verifies the book or study guide, in the languages you choose.

Elsewhere:a folder of recordings.

Engagement intelligenceSees

Know who you reached, without knowing who they are.

How many listened and in which languages, how long they stayed, what they opened, saved and shared afterwards, and whether first-time visitors come back. Counted anonymously, presented plainly.

Elsewhere:a headcount and a guess.

Live voice

One rule underneath all of it: engagement numbers are anonymous, and they stay separate from pastoral care. A listener becomes known to their church only by explicit opt-in, never by being counted.

Before Sanctavo, I filled in the blanks every Sunday. Not anymore.

Your message lives beyond the moment.

Every service automatically becomes a week of content: a clean transcript, a summary, the full message, a small-group guide, a blog draft, an email newsletter and a social caption, ready to review and publish, in the languages you care about.

Grace, not our own effort

This message unfolded how salvation comes by grace through faith, a gift received, not a wage earned. Anchored in Ephesians, with two supporting passages and a closing call to rest in it.

From one corner of the room

Barmak Shayan and Arsha Shayan, who build Sanctavo
The founders
Barmak ShayanFounder · Pastor and IT specialist. Builds the product.
Arsha ShayanCo-founder · Marketing & Church Partnerships. Web developer; built the website.

Sanctavo was built in Vienna by a father and son who experienced the language gap in their own church.

Sanctavo is led by its founders and tested in real services every week. Churches work directly with the people responsible for the product, onboarding and support. Every service is backed by infrastructure hosted in the EU and transparent data practices.

For years, we shared one room and one faith. But the message did not always reach everyone.

There was a wall between us that no one had built: language. Some people sat close enough to whisper the translation into one another’s ears, and every sentence had to pass through the pulpit twice. Sermons that moved people often fell silent when Sunday ended.

Read the rest

Some of those messages could have become a study guide, a booklet, or even a book. But they rarely lasted, and rarely crossed a language barrier. Valuable teaching in Farsi, Armenian, German, English, and many other languages remained inside one room simply because others could not understand it, and that loss went in every direction.

We could not accept that the message had to stop there. So we built, tested, and rebuilt.

Then we took Sanctavo beyond our home church, to a multilingual gathering in Thessaloniki. There, people who shared a faith but spoke different languages heard the same sermon at the same time, each in their own language.

Today, Sanctavo translates the message as it is preached and, after the service, helps turn it into a transcript, summary, study guide, booklet, or book draft, so that a church’s voice is not limited to one language or one Sunday.

Sanctavo began in one corner of that room, with a vision for a room that would no longer need that corner.

Questions people actually ask.

What equipment do we need?

A laptop or phone for the speaker's side, either plugged into your sound desk or set near the microphone, and internet. Nothing is installed in the building, and your congregation uses the phones already in their pockets. If your desk has a headphone or line output, that is the best feed.

Does the congregation need an app?

No. They scan a QR code, choose a language, and listen in the browser. No download, no account, no name. Adding the code to the bulletin or a screen slide is the whole setup on their side.

How many languages can run at once?

Every language you switch on runs in parallel, each with its own voice and captions. Your plan sets how many; most churches start with two or three and add one when a group actually arrives.

How many people can listen?

Listeners are not metered on the paid plans. Larger rooms are configured with you before the first service so we can make sure everything is ready.

What happens if the internet drops?

The speaker's stream reconnects on its own and listeners rejoin without doing anything; the transcript continues from the reconnection. A wired connection at the desk is steadier than the building's wifi, and it is the one thing worth arranging in advance.

Does it work with our livestream or presentation software?

It works with the audio: anything you can feed into a laptop. Direct plug-ins for ProPresenter, OBS or an RTMP stream are not built yet. If that is what you need for your setup, say so in the demo and we will tell you honestly where it stands.

How accurate is it, and can it make things up?

A glossary your team approves carries your names, scripture terms and phrasing into every translation, and a rolling correction pass fixes obvious slips in place. Answers and captions are designed to stay grounded in what was said and not to turn silence into words. Because the system uses AI, errors remain possible, and names, numbers and scripture references are the most likely places.

Where does our audio go, and is it used to train AI?

Sanctavo stores your recordings, transcripts and generated content on infrastructure in Frankfurt, Germany. Live audio and content may be processed by the AI providers and in the locations listed in our public sub-processor register. These providers do not use your service content to train their models. Source audio is off unless you turn it on, transcripts follow the retention window you choose, and a session with everything made from it can be erased in one action.

Which languages are supported?

Up to fifty-seven, depending on voice and caption availability: most arrive as a natural spoken voice, some as a plainer voice, and a few as captions only, because pretending a language sounds good when it does not helps nobody. Tell us the languages in your room and we will tell you which tier each lands in.

What does the Sanctavo logo mean?

The octagon is an old shape in the church: eight sides for the eighth day, the day after the week is done and something new begins. It is the shape of baptisteries and font covers, the place where a person is welcomed in. Inside it, the open V is a voice: rising, reaching out, asking to be heard. And the small gold line at its heart is what happens when it is: the one sentence someone carries home on a Sunday, the word that landed and stayed. That is the whole of Sanctavo in a single drawing, a voice in a holy room, understood by everyone in it, and kept. You will see it drawn large behind the first words of this page.

Can we start online, or do we have to book the demo first?

Both doors are open. Most churches book the free demo first: we set up one of your own services with you and listen together. A church that already knows what it wants can start a plan online from the pricing table; you confirm your email, pay by card, and we still set everything up with you before the first service. Nothing runs, and nothing is charged, until it is ready.
