What happens if Kairos puts the wrong verse on screen during the service?

Two safeguards. Every detection carries a visible confidence score in the operator panel — low-confidence hits never auto-go-live, they sit in a queue for the operator to approve or skip. And the operator always has a one-click "clear overlay" to pull anything off the broadcast instantly. The default posture is "surface, don't override": Kairos suggests, the operator decides.

What if our internet drops mid-sermon?

Kairos ships with a local Whisper model that runs entirely on the booth machine — no internet required for transcription or detection. If you use cloud STT (Deepgram, Gladia, or our managed option) and the connection drops, Kairos falls back to the local model automatically so the broadcast keeps moving.

Will the pastor notice a delay?

Typical end-to-end latency from the spoken word to the verse on the broadcast is 0.6 seconds. The pastor will not feel it; the congregation perceives it as the verse appearing as it's being preached, not after. The hardest case — a paraphrased quote — takes a beat longer because the semantic match runs after the phrase completes.

Who can hear the audio Kairos records? Where is it stored?

Live transcription audio is streamed to the STT provider you choose and is not retained after transcription — that holds for BYOK Deepgram/Gladia, our managed option, and local Whisper (which never leaves your machine). Optional session recordings are saved to your own cloud account on Kairos Cloud, accessible only to operators you invite. You own the audio; we don't train on it.

If our current operator quits, can the next volunteer figure this out?

Yes. Operators control Kairos from a single panel — Prev / Next / Send Live, with keyboard shortcuts and a queue of pending detections. Most teams hand it off to a new volunteer in under fifteen minutes. Setup happens once, on the booth machine, and survives reboots.

Kairos is a free desktop app that detects Bible verses in real time from live sermon audio. It listens to a sermon feed, transcribes speech as it happens, identifies scripture references (including paraphrased quotations), and renders broadcast-ready overlays via NDI for OBS, vMix, and other live production tools. Kairos is built with Tauri v2, a React frontend, and a Rust backend.

What equipment do I need to run Kairos?

A computer running Windows or macOS, an audio feed from your sound system (system audio, NDI, or a USB mic), and a projector or display screen on the output side. Kairos works with your existing audio setup and NDI-compatible switcher. No specialised hardware required.

What Bible translations does Kairos support?

Kairos supports KJV, ESV, NIV, NKJV, NLT, and more. You can switch between translations on-the-fly from the operator panel, and each translation is stored locally in your app database for offline use.

What happens if the pastor paraphrases a verse?

Kairos is trained to recognise paraphrased scripture references, not just exact quotations. A semantic / vector model surfaces the intended passage even when the wording differs from any source translation, and tags the match with a confidence score so the operator can decide whether to go live.

Do we still need a projection or media operator?

Yes, but their role becomes simpler. Instead of typing verse references into a search bar mid-sermon, the operator triages incoming detections — approving high-confidence hits, overriding the few that need correction. The job moves from data entry to judgement.

Does Kairos work with OBS Studio and vMix?

Yes. Kairos outputs broadcast-ready overlays via NDI, which integrates natively with OBS Studio, vMix, Resolume, and other professional live production software. The overlay is a single NDI source you drop onto a layer above your existing scene.

How do I get started?

Download the free desktop app for Windows or macOS, plug in your audio feed, and you're ready to go. Most teams are running in under five minutes. Full setup instructions live in-app and in the online documentation.

Is Kairos difficult to set up or use?

No. Kairos is designed for church teams of all technical skill levels. Setup is straightforward, and once running, it operates with minimal interaction during services.

How much does Kairos cost?

Kairos is free for every church when you bring your own transcription key (Deepgram or Gladia) or run our bundled local Whisper model fully offline. No account required, no usage limits. If you'd rather not manage a transcription account, every new account gets 2 free hours of managed transcription to try it — no card required. After that you can stay on a prepaid wallet ($10 ≈ 20 hours) or move to a Pro annual plan ($200/year with 60 hours included every month). See the pricing page for details.

What is managed transcription and do I need it?

Managed transcription means Kairos handles the speech-to-text connection for you — no key paste, no separate STT account, no surprise bills. We meter usage by the minute and charge a flat per-hour rate via Paystack. You don't need it: the free BYOK and local Whisper options work the same as they always have. Managed is purely for teams that want a single bill and zero setup.

Does Kairos do the same thing as Loghema?

Yes — both detect Bible verse references from live sermon audio in real time, including paraphrased quotations, and render them to broadcast. The differences are commercial and operational, not category. Kairos is free with a fully offline mode and a choice of STT provider; Loghema is a paid subscription with a broader feature surface (lyrics, mobile control, voice navigation) and a hybrid cloud transcription layer.

Can Kairos run fully offline like Loghema's offline features?

Kairos can run the entire detection pipeline offline using the bundled local Whisper model — including the speech-to-text layer. Loghema's site states voice transcription runs over the internet while other features work offline. If a fully offline service is a hard requirement, Kairos's local Whisper mode is the closer match.

How does Kairos's pricing compare to Loghema's?

Kairos is free for every church — no subscription required to run the desktop app or detect verses. Managed transcription is an optional add-on at $10 for a prepaid wallet or $200/year Pro. Loghema is subscription-based with monthly tiers (Starter through Max) listed in Nigerian Naira on loghema.com.

Can I use Kairos and Loghema together?

Both render to broadcast via NDI, so technically yes — but they're solving the same job. Most churches pick one as their scripture-detection source rather than running two simultaneously.
