If you've ever wished you could access a massive library of faithful preaching from anywhere in the world — for free — SermonAudio is that library. With over three million audio and video sermons from thousands of conservative Christian churches and ministries worldwide, it's the largest and most trusted platform of its kind.^1
Founded by Steven Lee in 2000, SermonAudio began with a simple desire: to give faithful churches a larger voice on the internet.^2 What started as a small website hosting audio uploads from select ministries has grown — by God's providence — into a global platform supporting unlimited sermon uploads, robust live webcasting, AI-powered sermon transcription, and native apps for iOS, Android, and Apple TV.^3 Every sermon on the platform — the entire library of over three million — has been transcribed using Vault AI, a fully local system with no cloud dependencies, making the full archive searchable by content.^4
SermonAudio's heart is preservation. The Vault — their physical server infrastructure — now spans four sites across three countries: Greenville SC (HQ), a remote arctic location in Canada, Northern Ireland (opened April 2026 at the LTBS Centre in Ahoghill), with more planned.^5 On November 7, 2025, the platform achieved "Independence Day" — moving all critical infrastructure (database, APIs, streaming, storage) in-house, fully under their own control.^6 In December 2025, the platform celebrated its 25th anniversary with a full-color book and short film documenting how a boy who fell asleep listening to cassette tapes of preaching grew up to build a platform reaching millions.^7
2025 was what founder Steven Lee called "an explosive year": Global Sermons launched with AI translation into 46 languages, a completely redesigned Broadcaster Dashboard went live, Smart Clips debuted for creating short-form vertical content from sermons, and a UK Parliament motion recognized the platform's work.^4 In 2026, development has accelerated further. The Ask! feature lets users ask theological questions in natural language and receive answers grounded in the sermons available on SermonAudio — every response includes complete citations to the source sermons, with the ability to listen directly to the exact excerpts.^9 Questions can be asked in any language and answered in the same language, drawing from three dedicated portals: ask.sermonaudio.com (site-wide, drawing from all Ask-enabled broadcasters), asksermons.com (single-broadcaster libraries), and askpuritans.com (Puritans and Reformers).^9 Smart Suggestions gives broadcasters one-click AI-generated sermon titles, Bible references, summaries, and tags — building on the existing Sermon Summarizer.^10 Smart Clips now supports Instagram Reels alongside other social platforms, and the Roku TV channel received a major v5.0 update with user account sync, bookmarks, and viewing history.^11 Over 1,800 C. H. Spurgeon sermons have been globalized into seven major languages through the Audiobook Initiative — reaching the halfway mark toward the entire Spurgeon corpus in Chinese, Russian, Portuguese, Spanish, German, French, and Persian.^13 And 1.8 petabytes of raw storage is being installed in The Vault UK to create a full storage replica alongside the existing Canada site.^14
Why Christians Love It"I've been using the first version of sermon audio app for years and it was always so glitchy, I gave up on it. I decided to see if maybe SA had a new update and lo and behold, sermon audio 2.0. Very nice update. Just what I needed." — iOS App Store Review^15
"I love that the new app shows listen count for both audio and video! Fantastic update... great new app!" — iOS App Store Review^15
