Hey Product Hunt, Quick one today. While building QueryTrace Audit, the single question I got asked most in the comments was "what's llms.txt and do I need one." So here's a tool that answers half of that on its own: QueryTrace llms.txt Checker. Enter any domain, yours or a competitor's, and we check whether it publishes a file at /llms.txt within seconds. No crawl of the whole site, no signup. To be straight with you: there's no solid evidence yet that having an llms.txt file changes how often AI models mention you. What it does do is give models a clean, direct summary of your site instead of making them guess from your homepage's nav and marketing copy. Low effort, can't hurt, and now you can check in ten seconds instead of wondering. If you don't have one, I built a companion tool for that too, dropping it in a couple weeks. For now, curious how many of you already have one without realizing it.
