Sermon library or your Sunday
SermonAudio is a library of preaching. Lumin is a companion for the message that was preached in the room you were standing in.
The direct answer
Choose SermonAudio if you want a library of audio and video sermons from churches and ministries, live services, and Ask! — an interface SermonAudio describes as answering questions from sermons on the platform with citations and clips. Choose Lumin if you use iPhone and iPad and you want help with the sermon you heard in your own congregation: a digest, cited passages, an Anchor, and a conversation for the week. SermonAudio is the stronger public preaching library. Lumin is the stronger personal sermon companion. Playing someone else’s sermon is not the same as keeping yours.

Where Lumin is stronger
SermonAudio is strongest at what it was built for. Lumin is built as a companion instead: answers with cited Scripture, the sermon you heard, spoken prayer, and memories you keep. That is where Lumin does better.
A short, honest reply with the passage named so you can open the text yourself — plus one next step.
Record or import the sermon you heard. Keep takeaways, an Anchor, one practice, and a conversation you can reopen on Wednesday.
Guided prayer and prayer walks with your eyes at rest. The guide helps you begin. It does not pray for you.
Keep the prayers and reflections you want to return to. Mark a prayer answered. Clear the record anytime.
Side-by-side
What each app says about itself on its public pages, set beside what Lumin actually does. It isn’t a scorecard, a ranking, or a roundup of reviews.
| Question | SermonAudio | Lumin |
|---|---|---|
| What it is forWhat is this app built to do? | SermonAudio presents a library of preaching: search, play, follow broadcasters, and — through Ask! — question that library in natural language. | Lumin is Bible AI for iPhone and iPad that carries a sermon from Sunday into the week: a digest with takeaways, cited passages, an Anchor, one practice, and a conversation you can return to. |
| Sermon follow-throughWill this help me live the sermon I heard on Sunday? | SermonAudio helps you replay sermons that churches have published to the platform. That is not the same as importing the message from your service this week and carrying that specific digest unless your church is already there and you treat playback as enough. | Record or import a sermon you are allowed to use. Lumin builds a digest with takeaways and Scripture references, helps you choose an Anchor and one faithful next step, and lets you ask the sermon a question later in the week. |
| Cited ScriptureCan I see the passage and check it myself? | Ask! is described as citing source sermons and clips. That is citation into preaching on the platform, which you should still test against the biblical text itself. | Short answers name the passage so you can open the text yourself. A sermon digest lists the references it heard. Treat every generated explanation as a fallible aid, not the Bible. |
| PrayerHow does the app treat prayer? | SermonAudio’s public pitch is preaching, playback, and sermon-grounded Q&A. It is not framed as spoken guided prayer or prayer walks. | Spoken, guided prayer and prayer walks — eyes at rest, room for your own words — with morning, midday, and evening rhythms. AI can prompt and structure a moment. It cannot pray. |
| Memory and continuityWhat persists from one day to the next? | Follows, bookmarks, and a personalized feed create a listening habit across many pulpits. Continuity is “return to the library,” not a private thread from your Sunday. | Keep the prayers, answers, and reflections you deliberately save. Mark a prayer answered. Clear the record anytime. Memory is something you choose, not a feed that owns your week. |
| PlatformsWhere can I use it today? | SermonAudio offers a website and an official app listed for iPhone, iPad, and Apple TV, with public materials also describing Android. | Native app for iPhone and iPad on the Apple App Store, plus a signed-in web companion at lumin.faith/app. Android is not available today. |
| Spiritual-authority limitsDoes the tool claim a role it cannot hold? | SermonAudio hosts preaching and, through Ask!, answers grounded in that preaching. A library of sermons still cannot replace your church or a pastor who knows you. | AI is not God, a prophet, a pastor, or a substitute for church. Lumin assists with organizing, study, reflection, and questions. Scripture, conscience, pastoral care, and Christian community stay in their proper place. |

The real difference
SermonAudio is a public preaching archive: churches upload, listeners play, and Ask! lets people query sermons that broadcasters have enabled. That is a real gift when you want faithful preaching beyond your zip code, or when your own church publishes there.
Lumin is not trying to host the world’s pulpits. It takes a sermon you are permitted to add — often the one from your congregation — and keeps the thread: digest, passages, Anchor, one step, a question you can ask later. If you want a library, SermonAudio matches the category. If you keep losing the message from your own Sunday, Lumin is the more personal tool.
Public sources
Everything we say about SermonAudio comes from what SermonAudiopublishes. We don’t invent ratings, review counts, prices, or features.
A non-negotiable boundary
A library, a chatbot, a Bible reader, and a companion can each help you begin. None of them can love you, answer for the counsel it gives, gather with you around a table, or replace Scripture read in context.
When an app starts competing with those things, it has taken a place that isn’t its own. That goes for Lumin too.
Questions people ask
Use SermonAudio to play and search a public library of preaching. Use Lumin on iPhone and iPad to keep the sermon from your church available through the week. Playing a library is not the same as keeping your Sunday.
Not as a global sermon archive. Lumin is an alternative for personal sermon follow-through, cited Bible answers, and spoken prayer.
SermonAudio describes Ask! as answers grounded in sermons on its platform. Lumin is built around a sermon you add and a week of practice. Both can be wrong; both should send you back to Scripture.
Then you can replay that file in the library. Lumin still does something different: a digest, an Anchor, one practice, and a conversation tied to that message.
No. Lumin is currently available for iPhone and iPad. SermonAudio publishes more surfaces for listening.
