Quick way to test if my llms.txt actually works?

I added an llms.txt but have no idea if the syntax is correct or if crawlers respect it. Is there a validator or live tester?

Before even uploading, I always test with https://txt-llms.com/ It has a built-in validator: paste your file (or generate one on the spot), and it instantly tells you if there are errors + shows exactly which bots are allowed/blocked. It even has a “test against real user-agents” feature that simulates GPTBot, ClaudeBot, etc. Saved me from embarrassing mistakes multiple times. Super lightweight and 100 % accurate.
