How to Submit llms.txt to AI Directories
Short answer: you don't. AI crawlers find your llms.txt file on their own. But you do need to make sure they can actually read it.
Last updated: March 2026
The key takeaway
There is no "Submit" button for llms.txt. You deploy the file to your domain root. AI crawlers find it automatically. That's the whole system.
Why llms.txt Doesn't Need "Submission"
If you've been searching for a form to submit your llms.txt file to AI directories, stop. That's not how this works.
llms.txt follows the same model as robots.txt. You place the file at your domain root — yoursite.com/llms.txt — and AI crawlers check for it automatically. No submission forms. No approval queues. No waiting.
This is by design. The llms.txt specification was built to be self-serve. You control your file. Crawlers respect the standard. That's it.
How AI Crawlers Actually Find Your File
Here's what happens when you deploy llms.txt:
Crawlers visit your domain
GPTBot (OpenAI), ClaudeBot (Anthropic), PerplexityBot, and others regularly crawl the web. When they visit your domain, they check well-known paths — including /llms.txt.
They read your file
Your llms.txt tells the crawler what your site is about, which pages matter most, and how your content is organized. It's a table of contents for AI.
Your content gets indexed
The AI system uses your llms.txt to understand and prioritize your content. When someone asks a question related to your expertise, you're more likely to be cited.
No middleman. No directory editor deciding whether to include you. The file speaks for itself.
Make Sure Crawlers Can Actually Access It
Deploying llms.txt is pointless if your robots.txt blocks AI crawlers. This is the number one mistake we see.
Check your robots.txt for lines like these:
Blocks AI crawlers (bad)
User-agent: GPTBot
Disallow: /
User-agent: ClaudeBot
Disallow: /Allows AI crawlers (good)
User-agent: GPTBot
Allow: /
User-agent: ClaudeBot
Allow: /
User-agent: PerplexityBot

The llms.txt Examples Directory
We maintain the largest catalogue of llms.txt implementations on the web. Over 840 real websites, organized by industry, quality score, and implementation approach.
This directory isn't a submission queue — it's a reference. We scan the web for live llms.txt files, verify them, and catalogue the results. If your site has a valid llms.txt file deployed, it's eligible to appear in our Examples Directory automatically.
Why does this matter? Because when developers, SEO professionals, and business owners research llms.txt implementations, they find our directory. Your site gets visibility from two angles: AI crawlers reading your file directly, and humans discovering your implementation through our catalogue.
How to Verify AI Systems Are Reading Your File
Trust but verify. Here's how to confirm crawlers are actually finding your llms.txt:
Check server access logs
Look for requests to /llms.txt from user agents containing "GPTBot," "ClaudeBot," "PerplexityBot," or "Googlebot-Extended." If you see them, crawlers are reading your file.
Use Crawler Access Analysis
Our Crawler Access Analysis checks 8 major AI crawlers against your robots.txt and confirms which bots can reach your site. No guesswork.
Run an AI Citation Check
The ultimate test: is AI actually citing you? Our AI Citation Check queries AI search engines with industry-specific questions and reports whether your domain appears in the responses.
llms.txt vs. Traditional Directory Submissions
If you've done SEO before, you're used to submitting your site to directories. Google Business Profile. Yelp. Industry-specific directories. That model is built on gatekeepers: someone reviews your submission and decides whether to include you.
llms.txt flips that model entirely.
| Traditional Directories | llms.txt | |
|---|---|---|
| How it works | Fill out forms, wait for approval | Deploy file, crawlers find it |
| Control | Directory editors decide your listing | You control the entire file |
| Updates | Submit change requests | Edit the file, crawlers see it next visit |
| Speed | Days to weeks | Immediate on next crawl |
| Cost | Often paid listings | Free — it's a text file |
The old model: beg for inclusion. The new model: make your content readable and let AI come to you.
