Bounded discovery
The generator reads public homepage, navigation and sitemap evidence, then inspects no more than 20 candidate pages.
Machine-readable site index // free
Free llms.txt generator and checker
Generate a concise, editable file from your public site—or check whether an existing one is correctly served, structured and linked. No login, email gate or speculative “AI score”.
1. Read
We inspect bounded public evidence from the homepage, navigation and sitemap.
2. Edit
You choose the links and approve every description. Nothing is treated as final automatically.
3. Publish
Copy or download a plain-text file and place it at your website root.
What the tool actually does
A tidy file—not a visibility promise
Deterministic checks
The checker tests observable structure, response type, duplicate or malformed URLs, descriptions and live-link responses.
You control the output
Every suggestion can be changed or removed. Pasted-content checks stay entirely in your browser.
FAQ
Keep the file in proportion
Crawlability, useful content and corroborating evidence matter more than this optional index. Run the broader free scan when you want to test those fundamentals.
Does an llms.txt file improve Google rankings?
No. Google says llms.txt is not used as a Search ranking signal. The file is an optional curated index for tools that choose to read it.
Does Clunky use AI to write the file?
No paid language model is required. The generator uses public titles, descriptions, headings, navigation and sitemap evidence, and every suggested line remains editable.
What does the checker test?
It checks whether the root file is reachable as plain text, whether its structure and URLs are usable, whether descriptions add context, and whether a bounded set of links resolves.
