Show HN: Bible Note Journal – AI transcription and study tools for sermons (iOS)

6 points

6 months ago

I got back into church a couple years ago and would try taking notes with Apple Notes. It was a struggle trying to type notes while focusing on the sermon. Honestly, it would have been easier to write it in a notebook but in the end I built this iOS app to solve that problem.

You can record audio during a sermon (or upload files), and it transcribes using Whisper, then generates summaries, flashcards, and reflection questions tailored to Christian content.

The backend is Spring Boot + Kotlin calling OpenAI's API. Instead of deploying the backend through one of the cloud providers directly I decided to go with Railway. Users are notified with push notifications when their transcription and summary are completed. The iOS app uses SwiftUI and out-of-the-box SwiftUI components.

I worked with Spring Boot + Java a few years back when in fintech so it was cool to try writing something in Kotlin. I'm also a full-time Flutter dev that has been trying to get into Native iOS development and felt like I found a good use case for an app.

Currently only available in the US/Canada App Store. There is a free 3-day trial that you can use to give the app a go.

The goal was helping Christians retain more from sermons and build stronger biblical literacy.

Happy to answer questions about the architecture, AI prompting approach for Christian content, or anything else.
