Who it is for
Catholics looking for local service times, or anyone researching parish schedules and recorded preaching in the United States.
Catholic Index
Parish, Mass time and homily lookup for US Catholics
Overview
What Catholic Index does
Catholic Index answers practical questions about Catholic worship in the United States. It locates parishes near a given place and returns Mass, Confession and Adoration schedules along with fuller parish details, drawing on a directory of more than 23,000 US parishes.
Beyond schedules, it identifies Masses that are streaming live on YouTube and searches recorded homilies by subject using semantic matching rather than exact keywords. Daily Mass readings are available with liturgical context and a short reflection, in English or in Spanish.
Sample queries include finding churches near Oakland, California, pulling the readings for the current day, or looking for homilies on a theme such as forgiveness.
What stands out
Semantic search over recorded homilies goes past the schedule lookup that most parish finders stop at.

Where Catholic Index is listed
Catholic Index is listed in the ChatGPT apps directory only. Mike Chang has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
