I created app.catur.org last year because I wanted to open my phone and quickly check the Malaysian Chess Festival schedule without having to search for the tournament PDF and open it. It grew as I added other info like prize structure, link to registration, player lists etc.

Then I made festival.catur.org because I like the name, as it sounds very close to  "chess festival" just from the URL. If you look at both mini websites, they have the same content.

So I asked Perplexity.ai what it thought the difference between the two websites and it responded:

Website purpose

app.catur.org appears to serve as a mobile-friendly companion app/site for festival participants, with quick access to schedules, player lists, results, venue maps, and news updates. It also still carries archived festival content from earlier editions, so it functions like a practical information hub during the event.

festival.catur.org is the official registration portal and event homepage for the 21st Malaysian Chess Festival 2026. It emphasizes sign-up, the event schedule, categories, and festival logistics, making it the main entry point for players who want to register or review the full event structure.

Perplexity got most of it right but not the official registration portal part. Both are not "official" but they do link the official registration page which is at DATCC website.

app.catur.org purpose is a static informational site for all the essential festival info which is mobile friendly - so as to be quickly referenced when needed.

festival.catur.org seems to have all the same content but it goes further to report on events as it happens - sort of like a blog and link to live results and the latest developments related to the festival.

So there! Think of app as the fast and efficient office assistant and festival as the hardworking reporter.
