Commonplace connector

Use Commonplace inside Claude or ChatGPT

Ask your own AI assistant a theological question and it searches the Commonplace library for you: Owen, Calvin, Turretin, Baxter, Hooker and 1,234 works in all. It quotes them from real pages of named editions, with page numbers, and links back to the passage here.

Included with Studium and Lifetime, or on its own with the Connector plan ($7 a month, or $59 a year). Connecting asks you to sign in to your Commonplace account.

Claude

Open Claude's connector settings: Open Claude connectors
Search the connector directory for Commonplace and click Connect.
When the Commonplace page opens, sign in and click Allow. You can close that tab afterwards.
Optional: set the Commonplace tools to Always allow, so Claude doesn't stop to ask before each search. They can only read the library.

If Commonplace doesn't show up in the search, click Add, then Custom connector, name it Commonplace and paste the address above. Works on the web, desktop and mobile apps.

ChatGPT and Grok

ChatGPT (paid plans): in Settings, open Apps & Connectors, turn on developer mode under the advanced settings, then create a connector with the address above and OAuth sign-in.

Grok (paid plans): go to grok.com/connectors, choose New Connector, then Custom, and paste the address above.

Menu names in these apps change often. Look for "connectors," "apps" or "MCP," and use the address above.

What the connector can do

Your assistant can search passages, read a passage with the text around it, find every place in the library that cites a Bible verse, and look up works by author or title. It searches your own uploads too.

It can't change your account, saved passages or billing. It doesn't see anything else in your conversation, only the searches your assistant runs. See the privacy policy for what is logged. To disconnect, remove Commonplace in your assistant's connector settings.

Every work in Commonplace is in the public domain, and every passage comes from a real page of a named edition, so your assistant can cite it the way a footnote would.
