What Waymark Is & Isn't

Waymark is a Reformed friend who loves to talk theology ... not the definitive voice on Christian doctrine, and certainly not a substitute for your church, your elders, or the Spirit working through the ordinary means of grace. Every answer draws from a curated corpus of hundreds of primary sources: Calvin, Augustine, the Puritans, the Church fathers, and others across the Christian tradition.

The alternative to curation isn't neutrality. It's an AI trained on the whole internet, which is a theological sewer. This is at least an attempt to steer toward something reputable — a tool built on sources the church has found useful for centuries, rather than the statistical blur of everything ever posted online.

Waymark doesn't pretend to cover every tradition or speak for all of Christianity. The corpus reflects a confessional, Reformed center of gravity, with voices from outside that tradition included charitably. These voices aren't props. They're fellow travelers worth hearing. The goal isn't to settle every debate. It's to showcase the best of what's been said so you can dig deeper yourself.

Logos is a research library. Waymark is a theological conversation partner. Both are valuable — they're just different tools for different purposes.

Questions You Might Have

Do I need an account to ask questions?

No. You can ask 3 questions as a guest to try it out. Create a free account for 10 questions per month with full conversation history.

How accurate are the answers?

Answers are generated by AI, grounded heavily in primary source texts. Every response cites its sources so you can verify and read the full context.

What texts are in the corpus?

The corpus includes 561 works — Calvin's Institutes, Augustine's Confessions, the Westminster Standards, the Puritans, Church Fathers, creeds and confessions, and, of course, Scripture.

Can I upgrade to unlimited?

Yes. Premium is $6/month for unlimited questions, full conversation history, and the ability to share conversations.

How does Waymark work? Is this just ChatGPT hooked up to some books?

No. When you ask a question, Waymark first searches the corpus using a combination of semantic similarity and keyword matching to find the most relevant passages. This isn't just dumb word matching, but conceptually related ideas. Only then does it ask an AI to synthesize an answer from those specific passages. Every claim is tied to a real, verifiable source you can read yourself.

Can the AI get things wrong or hallucinate?

AI can make mistakes. That's exactly why every answer cites its sources so you can verify claims and read the full context. Waymark is a study companion, not an oracle. If something feels off, check the citations. If you're still unsure, follow up with your pastor or elders.

Is my data private? Are my questions used to train AI models?

Yes, your data is private. Your questions are stored on Waymark's servers so you can revisit conversations, but they are never sold or used to train AI models. When your question is sent to an AI provider, no personal identifiers or conversation history are included — only the question text and relevant corpus passages. Account deletion permanently removes your user record and all conversations. Read the full privacy policy.

Can I share my conversations with others?

With a Premium subscription, yes. You can mark any conversation as public, which gives it a shareable URL accessible to anyone (no account required). Shared conversations are search-engine indexable, making them useful for study groups, blog posts, or reference links.

Can I suggest a work or author to add to the corpus?

Please! I'm always looking to expand the corpus with quality theological works in the public domain. Reach out through the contact form with your suggestion. If you're an author yourself, check out the partnered authors page. You'll get a free Premium subscription, dedicated profile page, and, soon, monthly citation analytics.

Can I use Waymark for sermon preparation or academic writing?

Absolutely. Waymark's sources are primary texts — Calvin's commentaries, Church Fathers, Puritans, creeds and confessions — the kind of material you'd consult for serious study. As always, verify citations yourself and treat it as a research assistant, not an authority.
