The preacher speaks.
The verse appears.

Pulpit AI listens for a scripture reference and puts it on the projector — no typing, no slides to build the night before. Runs on the church laptop, works without internet.

What it does

Built for the person running the screen on a Sunday.

No slide decks, no scrambling to find a verse mid-sermon. Just speak — or type — and it's up.

Speak the reference

Say “John 3:16” or even a loose paraphrase and the verse is found and projected. Hold-to-talk, or hands-free continuous listening.

Scripture & hymns

KJV, WEB and ASV ship with the app; hymns project stanza-by-stanza. Arrow keys or “next” walk through verses live.

Backdrops that fit the room

Choose a sanctuary gradient, a calm starfield, a living aurora — or drop in your own image. The congregation screen never has to be plain black.

Slides & announcements

Compose announcements, giving details with a QR code, or a quick notice — and put them on screen with one click. Bookmark the ones you reuse.

Presets & plugins

Save a whole service order and step through it. Enable extras like a live clock or slide templates — or write your own handler plugin.

Optional cloud accuracy

Off by default. Bring your own key to route transcription through Groq or resolve tricky paraphrases with DeepSeek — the verse always comes from the local Bible.

How it works

Three moves, and it's on the wall.

The operator stays in control — nothing reaches the congregation screen until it's meant to.

Speak or type

Hold the mic and say the reference, leave it listening through the sermon, or type it into quick reference. Live transcription shows what it's hearing.

Confirm the match

A confident match goes straight up. A borderline one waits as a card you tap to accept — so a mis-hear never surprises the congregation.

Project it

The verse, hymn or slide fills the second screen over your chosen backdrop. Step forward and back, or blank it, without touching a slide deck.

In depth

Everything under the hood.

The details that matter when you're the one trusted with the screen.

Voice & noisy rooms

Speech runs on-device by default (transformers.js), so audio never leaves the laptop. A speech-band filter, echo cancellation and adaptive voice detection lift the preacher's voice out of music and crowd noise, and a neural voice-activity filter drops non-speech before it's ever transcribed.

Live interim text appears while someone is still speaking, so you're never talking to a ghost. For the loudest rooms, an optional cloud transcription tier (Groq Whisper) is one toggle away.

Scripture, hymns & stepping

Bundled public-domain translations (KJV, WEB, ASV) work fully offline. Say a range like Romans 8:38-39, then step verse-by-verse with the arrow keys or “next”. Hymns project one stanza at a time, wrapped as sung lines rather than prose.

The projector screen

A dedicated congregation window scales type to the screen. Pick from built-in backdrops — Sanctuary, Midnight, Dawn, Aurora, Starlight — or use your own picture, with a dimmer so verse text stays readable. A live/preview toggle lets you line up the next thing without the congregation seeing you work.

Slides, presets & plugins

Compose announcements and giving slides (with a QR image), save reusable ones as bookmarks, and lay out a full service as a preset you step through. Extras ship as toggleable plugins — a digital clock, slide templates — and you can import your church's own hymnal or Bible as a content pack.

Privacy & the cloud

Offline is the default and the app is fully functional that way. Cloud tiers are opt-in, use your own API key, and fall back silently to on-device if a call fails. Even with the smart-matching tier on, the model only ever returns a reference — the scripture text itself is always read from the local dataset, never generated.

First launch downloads the on-device speech model once (~50–80 MB), then runs offline.

Bible translations

Not everyone uses the same translation.

Pulpit AI ships with the King James Version, World English Bible, and American Standard Version built in (all public domain). Need something else? A translation is just a content pack: one file, installed from inside the app (Plugins → "Import a hymnal or Bible…"). No restart, no reinstalling the app.

More translations, including how to add ones still under copyright, are on the wiki.

Cloud accuracy

Optional, and off by default.

Pulpit AI runs fully offline out of the box. In a noisy room, or when the preacher paraphrases a quote instead of citing chapter and verse, two optional cloud tiers can help: Groq for faster, more accurate transcription, and DeepSeek for matching a loose paraphrase to its verse. Both stay off until you turn them on in Settings, and each uses your own API key, billed by that provider directly, not by us.

Groq (transcription)

Faster, more accurate speech recognition in loud rooms.
  1. Go to console.groq.com and create a free account.
  2. Open "API Keys" in the left sidebar.
  3. Click "Create API Key", name it, and copy the key it shows you (starts with gsk_).
  4. In Pulpit AI: Settings → Cloud accuracy → "Cloud transcription — Groq Whisper" → paste the key.

DeepSeek (smart matching)

Resolves a paraphrased quote to its verse; the verse text still always comes from the local Bible.
  1. Go to platform.deepseek.com and create an account.
  2. Open "API Keys" in the account menu.
  3. Click "Create new API key" and copy it (starts with sk-).
  4. In Pulpit AI: Settings → Cloud accuracy → "Smart reference matching — DeepSeek" → paste the key.
Coming soon: a single Pulpit AI account, sign up once and subscribe monthly for both of these, no separate provider keys to create or manage. For now, during the beta, bring your own Groq/DeepSeek key as above; it works today and there's no obligation to switch later.
FAQ

Questions, answered.

Does it need an internet connection?

No. Everything core — voice recognition, scripture, hymns, projection — runs on the laptop with no connection. You only need internet for the one-time speech-model download and for the optional cloud accuracy tiers.

What if it mishears the reference?

Uncertain matches don't auto-project — they appear as a confirmation card the operator taps to accept or dismiss. You can also type any reference directly in quick reference, and blank the screen instantly at any time.

Which computers can run it?

Windows 10 or newer, macOS 11 or newer, and 64-bit Linux (AppImage or .deb). It runs on modest hardware — a smaller/faster speech model is available for older laptops, and a GPU is used automatically when one is present.

Can we add our own hymns or slides?

Yes — compose announcement and giving slides in-app and bookmark them, and lay out a full service as a preset. Developers can add capabilities through the plugin system documented in the wiki.

How much does it cost?

Pulpit AI itself is free. The optional cloud tiers use your own API keys and are billed by those providers only if you choose to enable them.

Ready for Sunday
