"He reasoned daily in the hall of Tyrannus… and all who lived in Asia heard the word of the Lord."
Acts 19:9–10
For confessional Reformed churches
Every sermon. Findable.
Tyrannus transforms your church's sermon archive into a searchable library: transcribed, indexed, and optimised for global discovery. Built for churches that preach from a confession and mean it.

Built for
Any church that preaches from a confession and holds to it. The doctrine is yours. We make it discoverable.
Tyrannus is built on confessional categories, not generic church tech categories. The Scholar's confession chapter browser, the sermon indexing, and the SEO content all understand the difference between Baptist, Presbyterian, and Continental Reformed confessionalism. Your tradition shapes how your sermons are understood and surfaced.

What Tyrannus does
01 —
Connects to where your sermons already liveSermonAudio and YouTube integrations pull your existing library automatically. Keep uploading where you always have. Tyrannus works with it, not instead of it.
02 —
Turns every sermon into a structured, readable documentEvery sermon is transcribed and formatted: section headings added for navigation, every Scripture reference detected and linked to the text, readable on any device. Not a raw transcript dump. A document a pastor could study.
03 —
Writes the descriptions your church never had time to writeMost SermonAudio and YouTube uploads go out with no description at all, or one written for people who were already in the room. Tyrannus generates titles and descriptions for every sermon in your archive, written for a stranger searching a theological question. Then pushes them back to your platforms automatically.
04 —
Publishes your library under your own presenceA fully hosted sermon library at your own address. Every church gets a subdomain like freegrace.tyrannus.ai, or point your own domain and use something like sermons.freegrace.ca. Indexed by search engines, owned by you, not buried on someone else's platform.
05 —
Surfaces related sermons by theological themeSermons are indexed by content, not just tags. A visitor who finds one sermon on justification finds five more they didn't know existed.
06 —
Your SermonAudio and YouTube presence improves automaticallyOptimised titles, descriptions, and transcripts sync back to your existing platforms. Sermons that have sat unseen for years become findable on SermonAudio search, YouTube search, and Google. No re-uploading required.
07 —
Upload your sermon notes to enrich the whole recordIf your pastor preaches from notes, uploading them transforms the sermon record. The outline structure, cross-references, and theological intent from the notes are used to improve the transcript headings, deepen the Scripture index, and produce a more accurate study guide, faithful to what the preacher actually intended to say.

Archive processing
Churches with more than 1,000 sermons pay a one-time $249 archive processing fee when they join. This covers transcription, indexing, and generating titles and descriptions for your full back catalogue. Ongoing new sermons are included in your monthly plan at no extra cost.
Note
Tyrannus works with SermonAudio and YouTube. It does not replace them. Your congregation keeps finding sermons where they always have. Tyrannus adds the layer that makes those same sermons findable by the rest of the world.
For individuals
The whole confessional pulpit. At your desk.
For the pastor who wants to know what faithful men have preached on a passage before he preaches it himself. For the elder working through a doctrinal question. For the seminary student who wants to read what sound men actually said about a text. Not just what one man said.

Scholar: what it means in practice
Confession chapter browser
Browse the 1689, Westminster, Belgic, or Heidelberg chapter by chapter. Sermons indexed by the doctrine they treat, not by tags—by content. Chapter 11 on Justification returns every sermon that addresses that doctrine across every church.
Scripture index
Look up any passage and find sermons where it is the primary text or quoted significantly within the message. A pastor preparing on Romans 3:21–26 finds every treatment across the whole library.
Reading mode
Formatted transcripts with paragraph breaks, section headings, and every Scripture reference linked to the text. Not a raw dump—a document built for study. Download as PDF.
Sermon outline
When a pastor uploads notes, the outline is extracted and published alongside the transcript. The argument as the preacher intended it, with cross-references intact. Download as PDF.
Research chat
Ask a question about any sermon or across the whole library. Every answer grounded in named sermons by named preachers, with the exact passage cited. No synthesis without citation.
Who is this for
Pastors preparing a sermon series. Elders working through a doctrinal question. Seminary students who want to read what sound men actually preached on a text. Anyone whose theological formation shouldn't be limited to what one pastor can cover in 52 Sundays a year.
