Psalmlog: FaithTech, Grief, and the Bad Spoon

·36 min·2 clips

Preston Zeller says Jesus would treat AI as a tool, not something inherently bad.

Leonard starts with a direct question. He asks Preston Zeller how he ended up at the crossroads of faith, technology, and business, then drifts through a bit of Mesa, Arizona weather talk before the conversation settles on PsalmLog. Preston says he grew up evangelical. He ties his Christian life back to church, then frames PsalmLog as a faith-tech product for Christians and seekers that aims at spiritual growth without picking a denominational side. The app runs on foundation models. Preston names Gemini, Claude, and OpenAI as the engines underneath it, and Leonard keeps pressing on what that looks like for someone who opens the app to look up scripture, journal, or pray. Preston stays practical. A user picks a theme such as seeking wisdom, general prayer, or giving thanks, and the app can pre-fill the session with a relevant Bible verse before it handles the rest of the journal entry. That verse matters. Preston says the system uses a RAG-style setup so the scripture stays in context, and he also describes the app as a study tool for someone who wants to read a passage, tag it, and write thoughts around it. He breaks the output into parts instead of keeping it vague. The response can include emotive analysis, a personal summary, scripture connections, next steps, and other categories built into the workflow, all meant to reflect back the shape of what the user shared. Leonard keeps translating. He restates Preston's point in plainer business language, asking whether the app is basically linking a person to biblical resources and then adding background explanation for whatever crisis or question they are carrying. Preston says yes, mostly. He also says the categories should become more personalized over time as the journal learns what the user reaches for, and that is where he sounds most grounded, more interested in the slow shaping than in any AI buzzword. The close turns personal. Leonard asks what memo Preston would write to listeners, and Preston answers with a simple line about grace: do not try to save yourself by your own works, because someone has already done the work for you. Leonard closes warmly, praises the purpose behind the project, and ends the show with a production sign-off and a call to like and subscribe.
