Read full description

Prepser is the sermon workflow for Evangelical pastors: catch thoughts through the week, prep the message without the blank page, and turn the sermon you preached into Monday's work — in your own words, in your translation. CAPTURE IN SECONDS • Speak a thought, snap a Bible or book page, paste text, or import audio, PDF and Word files. • Live on-device transcription while you record. • Thoughts, quotes and illustrations land in your library, ready when you sit down to write. PREP WITHOUT THE BLANK PAGE • Pin notes to a Prep: Sunday message, Bible study, small group, youth, devotional. • Generate an outline, key points and Scripture from your own material. • Ask your notes anything in chat — grounded in what you actually wrote and said. • Export as a Word file you can add to Logos as a Personal Book. PREACH. MONDAY'S DONE. • Record from the pulpit or drop in the audio. • Pin the recording to a Prep — Prepser drafts the outline, social posts, newsletter, small-group questions and prayer points. YOUR THEOLOGY, YOUR WORDS • Calibrated to your tradition: Baptist, Non-denominational, Pentecostal, Assemblies of God, Reformed, Methodist, Bible church. • Quotes Scripture in your translation — ESV, NIV, KJV, NKJV, CSB, NASB, NLT. • We don't write sermons. That's between you, the text, and the Spirit. Prepser works from your notes and the sermon you preached. • Your recordings and notes are never used to train AI and never sold. ALSO • Import church events from your calendar. • Folders for thoughts, quotes and illustrations. • Sign in with Apple to keep your library across devices — optional. FREE TO START No account needed.
