AI Chat for pastors that knows your own sermons

AI Chat in Prepser answers from your own library: the sermons you recorded, the notes you scanned and typed, and the preps you built during the week. Ask what you have preached on recently, where you collected an illustration, or what is missing in Sunday's outline, and the answer shows the notes and preps it came from. Good answers can be saved back to your library as a note or a prep.

Where: AI Chat tab · Home → Type a topic or ask anything · a prep → Ask anything about this prep...
Searches: Your notes (transcripts, scans, typed notes and their material) and your preps (brief, material and study notes)
Free plan: 30 AI chat messages a month

What makes it different from a general AI chat

A general chatbot knows a great deal about the Bible and nothing about you. It has not heard last month's series, it does not know the story you told about your grandfather's farm, and it cannot tell you that you already preached Romans 8 twice this year. Prepser's AI Chat starts from your library, so its answers build on your preaching instead of replacing it.

It searches before it answers. Every question is matched against your notes and preps first, and the answer is written from what it finds.
It shows its sources. Under an answer, Sources lists the notes and preps it drew on. Tap one to open it.
It quotes your translation. Scripture comes in the Bible translation you chose in onboarding, and the answer comes in the language you wrote in.
Your library stays yours. Your recordings and notes are never used to train AI models and never sold.

Questions pastors ask their own library

When you open AI Chat, three starters show what it is for:

What have I preached on recently? A quick look back before you plan a series, so you do not repeat yourself or leave a gap.
Where else does Scripture speak on forgiveness? Cross-references for the theme you are working on, with the passages you have already preached on it.
Ideas to illustrate Romans 8:28: ideas for the verse, drawing on the illustrations already in your notes.

Beyond the starters, type anything into Ask anything.... For example: which stories have I used about grief, what did I say about the prodigal son's older brother, or give me three ways into Psalm 23 that I have not used before.

How to use AI Chat in Prepser

Tap AI Chat in the middle of the tab bar, or type into Type a topic or ask anything on Home.
Ask your question, or tap one of the starters. The answer comes from your notes and preps, with Sources underneath.
To keep the answer, tap Save as note or Save as prep. It joins your library and AI Chat can find it next time.
To narrow the search, tap Context · All and pick the notes and preps to focus on. Everything else is still searched; Use everything goes back to the whole library.
Your conversations are kept in Chats. Tap New Chat to start a fresh one, or search old ones to find an answer again.

Chat about one sermon or one prep

AI Chat also opens on a single item, and then it already knows what you are looking at.

On a prep: tap Ask anything about this prep... under it. Starters include How can I strengthen this prep?, What's missing in the outline? and Suggest illustrations for the main points.
On a note: starters include Summarize this note, What are the key points? and Turn this note into a prep.
From Home: under Build from a sermon, rows such as Small-group questions, Prayer points, Sermon summary and 5-day devotional ask you to Choose a sermon, then open AI Chat on it and write that piece for you.

This is how one Sunday sermon becomes small group questions, prayer points for the week and a devotional for the church, all in the same conversation, all from what you actually preached.

Drafts and study from the same chat

AI Chat is also where new work starts. Tap Draft a sermon for a first draft from a passage or topic that builds on your notes and preps; more on that in the AI sermon draft generator. Tap Study a passage on Home for context, key words and cross-references on a text, then Outline a sermon from this when you are ready to shape it. For study notes that stay attached to a prep, see study notes and preps.

Frequently asked

Is AI Chat free?

Yes, to start. The Free plan includes 30 AI chat messages a month, shared across AI Chat and the chats on a note or a prep, and the count resets on the first day of each month. Draft a sermon uses your 3 monthly sermon drafts instead of chat messages. Prepser Pro removes the monthly limits; see pricing.

What does AI Chat search?

Your notes and your preps. For a note, that is the transcript or scanned text, your own comment and the material Prepser built from it, such as key points and the outline. For a prep, it is the brief, its generated material and its study notes. To focus on a few items, tap Context · All and pick them.

How is this different from asking ChatGPT?

ChatGPT starts from the internet; AI Chat in Prepser starts from your sermons and notes, and shows which ones it used. It also quotes Scripture in the translation you chose and saves answers into the same library. The full comparison is on Prepser vs ChatGPT.

Can I chat in Portuguese, Spanish, French or Korean?

Yes. AI Chat answers in the language you write in, and quotes Scripture in the translation set in your profile. You can preach in English, Spanish, Portuguese, French or Korean.
