What is Loghema?

Real-time scripture detection for live sermons — from spoken word to on-screen verse in under two seconds.

Overview

Loghema is a desktop application that listens to live sermon audio, detects Bible verse references in real time, and instantly displays the full scripture text on your church's projection system. The entire pipeline — from spoken word to on-screen verse — completes in under two seconds with no manual intervention required. You'll see the gold detection indicator pulse in the status bar each time a reference is caught.

It was built specifically for churches that want their congregation to follow along with scripture without relying on a volunteer to manually look up and display each verse as the pastor speaks. Loghema removes that bottleneck entirely — your tech team can focus on audio, lighting, and cameras while verses appear on screen automatically.

Note

Live transcription uses a secure cloud speech-to-text service. Your audio is never stored on our servers — it's processed in real time and immediately discarded. Bible data and verse detection run entirely on your device.

Key capabilities

Real-time detection — identifies scripture references within 0.5 seconds of being spoken, including direct citations, partial references, verbatim quotations, and semantic paraphrases
Multiple Bible translations — supports ESV, NIV, KJV, NLT, NASB, CSB, NKJV, AMP, MSG, RVR60, and many more, with dual-translation side-by-side display
Projection integration — NDI output for OBS, vMix, Wirecast, and ProPresenter; direct secondary-display rendering; song library import from EasyWorship and OpenLP
Fully autonomous during the sermon — once you press GO LIVE at the start of preaching, Loghema operates without manual input. Press stop when the sermon ends and scripture is no longer being referenced (e.g. during worship, praise sets, or announcements) to avoid unnecessary transcription.
Confidence scoring — every detected verse includes a confidence value (0–1) shown in the detection card UI, and you set the threshold that controls when verses appear on screen
Session history — every verse detected during a service is logged with timestamps in the session panel, exportable as CSV or JSON
Offline capable — once Bible translation data is downloaded, detection works without an internet connection, only TRANSCRIPTION needs Internet Connection
Local REST API & WebSocket — build custom integrations, dashboards, or logging pipelines with the built-in developer API

How it works

Loghema follows a four-stage pipeline that runs continuously while detection is active:

Audio capture

The app captures audio from your selected input source — a USB mic, audio interface, virtual audio device, or a direct feed from your sound board. The waveform visualizer in the status bar shows real-time audio levels so you can confirm signal is flowing.

Speech-to-text

Audio is streamed to a secure cloud speech-to-text service optimized for natural spoken language. Transcripts return in under a second and are never stored — they're used only to detect scripture references, then discarded.

Verse identification

The transcript is parsed by a scripture detection engine that recognizes four types of references: direct citations ("John 3:16"), contextual references ("the next verse"), verbatim quotations, and semantic paraphrases. Each match is assigned a confidence score shown in the detection card.

Display output

Verses that pass the confidence threshold are sent to your configured output — NDI, direct screen, or the local API. The verse text is pulled from your selected Bible translation and formatted according to your display theme.

Use cases

Sunday services — automated verse display during the sermon, freeing your tech team to focus on other responsibilities
Wednesday night Bible study — display verses on a TV or monitor as the leader references them in a smaller setting
Multi-campus streaming — use the NDI output to feed verse data into a live-stream overlay for satellite campuses
Sermon archiving — export the session history to create a verse-indexed record of each sermon
Bilingual services (Coming Soon) — display the same verse in two languages simultaneously for multilingual congregations
