No connection required, ever

Church presentation software that never needs the internet

NaveLight is offline-first church presentation software: every feature, including the AI, runs on your own computer. The Bibles, the hymns, the speech models and the scripture search are all installed locally. There is no account to sign into, no licence check that can block a launch, and nothing is uploaded — so the software behaves on a full Sunday exactly as it did in an empty room on Thursday.

What runs locally

Not "works offline for the basics". This is the whole list, and there is nothing on the other side of it.

Bibles: Six translations installed with the app, plus a cross-reference index.
Hymns and songs: 1,700+ public-domain hymns bundled; your own library stored locally.
Speech recognition: Whisper models installed on the machine. Audio never leaves it.
Scripture search: The meaning-based index runs on device, not as an API call.
Media: Your videos and images, on your own disk.
Phone remote: Served over your local Wi-Fi, not routed through the internet.

Why offline matters

Built for Sunday mornings.

The room is full, the band is on, and three hundred phones have just found the church Wi-Fi. That's exactly when software that needs the internet starts to struggle. It's also the moment NaveLight behaves precisely as it did in rehearsal, because none of it was ever coming from anywhere else.

With NaveLight

The Bibles and the hymns are already in the app

The listening happens on your computer, not somewhere else

Your songs, media and services live on your own machine

The phone remote works over your own Wi-Fi

No account. Nothing to sign into on a Sunday morning

What's said in your building stays in your building

With software that needs the internet

Your content arrives when the service is already starting

The clever features are the first ones to go

A licence check can stop you opening the app at all

A busy Wi-Fi network becomes something you have to worry about

Someone else's bad morning becomes yours

Your sermon audio may be processed somewhere you can't see

Set it up once, then forget about it

NaveLight looks at the computer you're installing it on and tells you which listening model it can handle. Download it once and it's yours. No subscription running in the background, nothing to renew.

SPEECH Whisper · tiny.en → large-v3-turbo installed

SEARCH Scripture search · embeddings installed

REASON Advanced reasoning · ranking optional

SUM Summarization · key points optional

The rest of NaveLight works with no model at all. You just won't get the listening until you add one.

Try unplugging it

Pull the network cable out in the middle of a service. Nothing happens. No warning banner, no reduced mode, no feature quietly switching itself off.

Private, not just promised

Your sermon audio stays on the machine because there's nowhere else for it to go. The phone remote is switched off until you turn it on, and even then nothing works without the code you scanned.

It travels

A church plant in a school hall runs exactly the same as a main campus. There's nothing to install in the building itself.

Why it's rare

Why most church software can't say this

Most presentation software works offline for the basics and then checks a licence periodically, which is usually fine and occasionally catastrophic. AI features are a harder problem: transcription and passage search are expensive to run, so almost every product that offers them sends your sermon audio to a server and bills per minute. That model cannot work without a connection, and it means the audio leaves the building.

NaveLight puts the models on your machine instead. It costs us nothing per service, which is why AI Assist is included rather than metered — and it is why there is no grace period to run out.

Straight answers

Offline, specifically

What happens to NaveLight if the church internet goes down mid-service?

Nothing changes. There is no reconnect banner, no reduced mode and no feature that quietly switches itself off, because nothing was being fetched in the first place. You can pull the network cable out during a service and the congregation will not be able to tell.

How can AI scripture detection work without the internet?

The models are installed on the computer rather than called over a network. Speech recognition, the Bible index and the meaning-based search all run locally, so the only limit is the machine's own processing rather than the connection. This is why there is no per-minute transcription cost and no usage cap.

Does NaveLight need an account or a licence check?

No. There is no account to sign into and no periodic licence check that can block a launch. This matters most on the mornings it would matter most, when the building's Wi-Fi is carrying three hundred phones.

Still have a question?

Ask us anything, including the awkward ones. A real person answers, and if NaveLight isn't right for your church we'll say so.
