How it works
The Bible, read in the voices that matter to you.
Lux lets you hear the Bible read aloud in voices that matter to you — your own, a parent’s, a grandparent’s, a spouse’s. One person in the household records once. Lux generates audio narration of the Bible in that voice, chapter by chapter. The whole family listens, in the car, at the kitchen table, at bedtime.
There are two ways into this, depending on who’s setting it up. Pick the one that fits.
For parents setting up the family
You record once. Your family listens as often as they want.
You’re the renderer. You’ll capture a voice (yours, your spouse’s, a parent’s), wait while Lux generates the audio, and then everyone in your household — kids included — can listen in their own profile.

Make an account
Sign up with email or Google. You're the only one who needs to sign in. This is the household account.

Add a listener for each family member
From the Profile tab, add a listener profile for each person. Give each one a name and a color — kids who can't read yet recognize their color. Each listener keeps their own place in every chapter, so siblings can share an iPad without losing their spot.

Enroll a voice
Record yours in the browser (about 90 seconds reading three short passages), or send a private link to a parent or grandparent so they can record on any phone or laptop — no account needed for them. Every voice on Lux is recorded by the person it belongs to, with their consent captured before the first word.

Listen to the preview
Lux renders three short Psalms in the new voice as a quality check before committing to a full book. Takes a couple of minutes. If it sounds right, approve. If something's off, re-record with a fresh sample.

Render a book — or the whole Bible
Pick any book in the library and render it in the approved voice, or commit to all 66 books at once. The whole Bible takes 8–12 hours of unattended GPU time. We preview Genesis 1 & 2 first, and you have to type RENDER to confirm before the full job kicks off.

Hand the iPad to the kids
Sign into your account once on each device, then switch to that child's listener (the avatar in the top-right). The cookie remembers — from then on, each kid taps their home-screen bookmark and listens. No login, ever, for them.
For someone who wants to hear a family member’s voice
Ask the person whose voice you want.
Maybe it’s your dad, who’s on the road and you wish you could hear him read with the kids at night. Maybe it’s your mother, before she forgets things. Maybe it’s your husband’s voice for kids who haven’t met him yet. The path here starts with a conversation.

Send them luxbibles.com and ask them to record
Have the family member whose voice you want sign up and record their voice — about 90 seconds reading three short passages. They can also do it without an account if you (or anyone else with Lux) sends them a private invite-to-record link.
- 2
They render the books that matter
They pick a book — Genesis is a good place to start — or commit to the whole Bible. Rendering happens once and lives in their household account.
- 3
They add you as a listener in their household
From their Profile tab → Listeners → Add a listener. They give you a name and a color. The voices they've rendered are now reachable from your listener profile.

Sign in on a device they share with you
On your phone, an iPad they hand you, or a tablet you set up together — sign in once with their household credentials. Then switch the listener to your name from the avatar in the top-right. From now on, that device defaults to you.

Tap a chapter, listen anywhere
The Library tab shows everything that's been rendered. Tap a book, tap a chapter, listen. Your resume position is yours alone — they won't see where you've been, you won't see where they've been.
A few things to know
Public-domain and openly-licensed translations.
Lux uses Bible translations that are either in the public domain or made available under permissive open licenses. You can see the full list — with publisher, license status, and attribution — at /translations. You can’t upload other texts.
The AI voice is a reproduction, not a perfect copy.
The synthesized voice captures the cadence and warmth of the original recording but isn’t a perfect copy. Some voices clone more faithfully than others; longer, cleaner source recordings generally sound better. The audio is always labeled as AI-generated wherever it plays.
Voices stay private.
Your voice samples and rendered audio are visible only to your household. We don’t sell them, share them with anyone outside the household, or use them to train models. See the privacy policy for the full picture.
Consent is required.
If you invite someone else to record, they have to read and agree to the consent text before recording. Their agreement is timestamped and logged so the audit trail is honest.
You can delete everything, anytime.
Profile → Delete account schedules a permanent deletion in 30 days. Sign back in any time during that window to cancel. After 30 days everything goes — voice samples, rendered audio, the account itself.
