Can't find these menus? Their names change from time to time. Look in your app's settings for "connectors" or "MCP".
3. Sign in
- A sign-in page opens. Type your email address.
- Type in the code that's emailed to you.
You can sign in with GitHub instead, but you don't need to. Sign-in is handled by WorkOS: see what happens to your question.
Then ask a question
Start a new conversation. If your app has a tools or connectors button near the message box, make sure the library is switched on. Then ask, for example:
- Search the Christian Open Library: what did Calvin teach about the Lord's Supper?
- What did Spurgeon say about Psalm 23?
- Which historic writers cited Isaiah 53?
Naming the library in your first question helps your app know to use it.
Good to know
- Your AI app writes the answer. Check a quotation against its source before you print or preach it. How to check it.
- If you remember only the gist, try two or three phrasings, or one distinctive phrase.
- Each person has a fair-use daily limit.
- Stuck? Write to hello@christianopenlibrary.org and say which app you use.
