About Tolle Lege

What is Tolle Lege?

“Tolle lege” — “take up and read” — are the words St. Augustine heard in a garden in Milan, words that changed the course of his life and the history of the Church.

That’s what this tool is for. You have a question about the faith. Tolle Lege helps you find the passage, so you can open your Catechism or Bible and read it yourself. No fees. No generated answers. Just the texts.

Search, not generation

Chatbots can sound convincing about the faith, but they invite us to offload wisdom, understanding, and counsel — gifts of the Holy Spirit meant to be exercised by us individually, as humans made in the image of God. If you want to chat about the faith, talk to a person: a spiritual director, a pastor, a friend. AI “will never be able to share faith.”

But technology can serve the faith the way a good library does — by helping you find what you’re looking for. As Pope Leo has said, “the challenge is not to stop digital innovation, but to guide it.” Tolle Lege points you to the text. What you do with it — the reading, the reflecting, the praying — that’s yours.

How it works

Ask a question the way you’d ask a friend. Tolle Lege finds passages that speak to your question, even when the exact words don’t match. Search “Why does suffering exist?” and you’ll find passages on the mystery of suffering, the redemptive value of pain, and Christ’s Passion.

Every result is a direct quotation. No AI commentary, no paraphrasing. The texts speak for themselves, and they’re meant to send you back to the book.

Your privacy

Tolle Lege has no accounts, no cookies, and no ads. We do not collect your name, email, or IP address.

We do keep anonymous records of what people search for and which results they find helpful. This is how we improve the search. Each record is tied to a random session ID that your browser generates fresh every time you open a new tab — it cannot be traced back to you, and it disappears when you close the tab.

Your search queries are sent to third-party AI services (OpenAI) to find the best matches. We also use Vercel Analytics for basic page-view counts and Sentry for error monitoring. None of these services receive your identity because we never have it in the first place.
