Key takeaways

The short version.

  • Catholic Reminders names the day's feast and saint, with the readings as citations and USCCB links. It gives you the name; it does not write a long biography.
  • Perplexity's help center describes answers with numbered links to the sources it used, which suits a follow-up like who was this saint and where can I read more.
  • Perplexity's help center describes custom remote connectors, so you can try adding the app's MCP address yourself if your account allows it.
  • The connector page does not say which plans include custom connectors, and organization members need an admin to allow them. Check your own account.
  • Treat Perplexity's answer as a set of leads. Check it against Church sources, and ask your priest about anything that matters. Nothing here is an official integration.

Who it is for

Who is this pairing for?

  • Catholic Reminders delivers the liturgical calendar, feast days, saints, readings, prayers and context for what is happening in the Church.

  • The app tells you what the Church keeps today.

It is for Catholics who see the saint or feast of the day and want to know more: parents who want a few true sentences for the dinner table, catechists and teachers, parish volunteers, RCIA candidates and anyone who likes to read the sources behind a name.

Catholic Reminders delivers the liturgical calendar, feast days, saints, readings, prayers and context for what is happening in the Church. It is an independent resource and is not endorsed by the Vatican, the USCCB or the Catholic Church. Perplexity is an AI answer engine that cites the pages it read.

The app tells you what the Church keeps today. Perplexity helps you find where to read more. This is not an official integration, and AgentStructure has no partnership with Perplexity.

Use cases

4 ways people use Catholic Reminders + Perplexity.

  1. Saint of the day

    1. Ask who today's saint was, with sources

    Start with Catholic Reminders to see the saint or feast it names for today. Then ask Perplexity for a short background on that saint: when and where they lived, what they are known for, and links for each point.

    Open the sources before you repeat anything. A page from a diocese, a religious order or a Church publication is a better base than an anonymous post, and the numbered links let you tell the difference.

  2. Feast background

    2. Understand why a feast is kept

    Some feasts are familiar and some are not. Ask Perplexity what the feast commemorates and how its observance has developed, and to cite each claim.

    Compare what it returns with the app's own context and with a Church source such as the USCCB, which the app links for the readings. If the sources disagree, say so rather than picking one quietly.

  3. Short talk

    3. Prepare a few words for a class or the family table

    Paste the day's name into Perplexity and ask for three facts you can check, each with a link. Read the pages, then write the two or three sentences yourself.

    That keeps the talk yours, and every sentence has a page behind it that you have looked at.

  4. Reading list

    4. Keep a reading list for the saints you like

    When a saint catches your attention, ask Perplexity for a few places to read more, such as a biography from a religious order or a primary writing, with links.

    Save the links you trust. Perplexity can miss things or surface old or wrong pages, so the list is only as good as your reading of it.

How to

How do I use Catholic Reminders with Perplexity?

  1. Step 1

    Sign up free at [catholicreminders.org](https://catholicreminders.org), open the Connect your AI page and create a personal token. Save it, because it is secret. The remote MCP address is https://catholicreminders.org/api/mcp.

  2. Step 2

    In Perplexity, open Plugins, or Customize and then Connectors. Per its [help center](https://www.perplexity.ai/help-center/en/articles/13915507-adding-custom-remote-connectors), choose Add custom, then Add MCP connector, and select Remote.

  3. Step 3

    Enter a name and the address, which must use HTTPS. The help page lists None, API Key and OAuth 2.0 as authentication options. Pick the one your screen lets you use with the token, tick the acknowledgement box and click Add.

  4. Step 4

    Click the connector card to authenticate and enable it, then ask what the saint or feast of the day is. Review the answer and its sources yourself.

  5. Step 5

    If you cannot add it, copy the day's saint or feast from Catholic Reminders into Perplexity and ask for sourced background there.

Perplexity's help page does not say which plans can add custom connectors. Organization members need an admin to turn on Allow members to add custom connectors, and the page warns that Perplexity cannot verify third-party servers, so only add connectors you trust. Catholic Reminders is not listed in Perplexity's directory or built into it.

FAQ

Frequently asked questions.

Is Catholic Reminders an official Perplexity integration?

No. There is no partnership, listing or built-in integration. Perplexity describes custom remote connectors, and you add the app's address yourself if your account allows it. Otherwise you can paste the day's saint or feast into a Perplexity chat.

Does my Perplexity plan support custom connectors?

Perplexity's help page does not say which plans include them. In an organization, an admin must turn on member-added connectors, which is off by default. Check your own account.

Can I trust Perplexity's account of a saint?

Treat it as a lead. It finds pages and cites them, but it can miss things or surface old or wrong pages, and AI answers can contain mistakes. Open the sources and compare them with Church sources. For questions of faith, ask your priest.

Is the calendar right for my diocese?

The app uses the U.S. Roman calendar. Local rules and celebrations can differ, so follow your parish or diocese when they do.

What does it cost?

The apps are free during the beta, and the site shows the free and premium parts. Check the site for the current status.
