Three commentaries open, a sermon due in nine hours, and a chatbot that would happily invent a church father to fill the gap. OpenLumin is the answer to that moment: research you can actually trust.
Generative models are trained to sound right, not to beright. Ask most of them a hard question about a Hebrew participle and they'll produce a fluent, plausible, unsourced paragraph — sometimes true, sometimes a hallucination wearing a scholar's coat.
For a shopping list, fine. For the text people build their lives on, unacceptable. So we inverted the model: OpenLumin retrieves from named works and refuses to generate theology. If the sources are thin, it says so.
“A pastor shouldn't have to choose between a tool that's fast and a tool that's honest. We refuse to make them pick.”
OpenLumin is a project of AI Fluency Ministry. Individual access is free and will stay free. Church Plan subscriptions cover the cost of licensing scholars and running the infrastructure — nothing more, nothing hidden.
Every source in our corpus is named, licensed, and documented in public. We publish our citation policy, our provenance, and our denomination framings — because a research tool that asks for your trust owes you its receipts.
Every search, every citation, every lesson runs on paid AI inference and database calls. A $5 coffee covers about an hour of server time. A month of coffees keeps us online.
No tiers. No paywall. Just one coffee if the tool has helped you study.
