For Christians who want to dig into theology without funneling every question through a general-purpose AI trained on the whole internet, Waymark offers a grounded alternative.^1
Waymark is a theological conversation tool that answers your questions using a curated corpus of more than 550 primary sources from church history — Calvin, Augustine, the Puritans, the Church Fathers, the Westminster Standards, and more. Ask in plain language and it runs a semantic search across the corpus, then synthesizes an answer in which every claim is tied back to a real, citable source you can open and read in full.^1 A "Compare" view lets you see how Reformed, Catholic, and Lutheran traditions weigh in on the same question side by side.^3
Built by Alex MacArthur, a senior software engineer in Tennessee, the corpus reflects a confessional, Reformed center of gravity while charitably including voices from outside that tradition.^1 Waymark is upfront about what it is and isn't — "a Reformed friend who loves to talk theology," not a replacement for your church, your elders, or the ordinary means of grace.^1
Waymark is a web app with no native iOS or Android version. It's free to start with a set number of questions each month, and an optional subscription unlocks unlimited use and shareable conversations.^2
Notable- Every answer is footnoted to its primary sources, which users can open and verify themselves.^1
- Authors whose works appear in the corpus are cited by name, with a dedicated profile page.^1
- A side-by-side comparison with Logos clarifies how the two tools differ — Waymark as a conversation partner, Logos as a research library.^3
