One toolkit for everything machine-readable about your site.
Whether you're a webmaster shipping AI and search files, or anyone who just needs to see what's hiding inside a photo, MP3 or document — it's all here, free, and runs entirely in your browser.
Three kinds of file, and we tell you honestly which is which
Some of these files are decades-old internet standards. Some are two-year-old proposals still finding their feet. A few are conventions a handful of tools have started using with no formal spec at all. We badge every single one so you know exactly how much weight to put on it.
Formal standards or long-settled conventions with real, working enforcement — robots.txt, security.txt, ads.txt, manifest.json, llms.txt.
Active proposals with competing drafts and partial support — worth publishing as a clear signal of intent, not yet something to rely on alone.
No governing spec at all — useful, low-cost extras that some AI tools are starting to look for, but nobody guarantees they'll be read.
