The logical next step: your verified entry in the AI directory. That way you give ChatGPT, Gemini, Claude & Perplexity your verified first-hand data — instead of letting them guess or name your competitor.
llms-full.txt (detailed AI format), top placement.
Platinum€ 19,99A fixed spot at the head of the directory, named explicitly in llms.txt.
Diamond€ 49,99Permanently at the very top, preferred inclusion in both AI files.
All prices are final (§ 19 UStG, no VAT). One-time payment per entry — no subscription, no recurring costs.
No. There is no subscription — you pay once per entry. The standard entry is and stays free.
AI systems can read your verified first-hand data and recommend you, instead of guessing (hallucinating) or falling back to the more easily readable competition.
You only provide what should be publicly visible. No forced tracking, no tracking cookies, servers in Germany.
A few minutes: enter the URL, check the details, submit. We automatically create a missing llms.txt for you.

List your website for free nowThe decisive question: does your website appear in those answers?
AI systems recommend what they can understand. If your website is hard for AI to read, better-structured competitors may get named instead.
With llmstxt.info you make your website easier for modern AI systems to understand — and easier to find.
Whoever is visible to AI today gets found tomorrow.
Live GEO-score comparison — llms.txt, structure & AI-readiness. Free.
Real organizations in the directory — and more every day.
Listed organizations appear in AI-generated recommendations — whenever someone asks for providers, tools or experts in your category.
Structured AI discoverability is still an open channel. Whoever is present now builds compounding authority.
Standard listings stay in the directory permanently once approved — no subscription, no expiry date.
A single enterprise inquiry through an AI recommendation covers the cost of any premium plan — several times over.

Our AI cleans up your llms.txt & llms-full.txt — spec-compliant, without navigation and cookie clutter, with a clear summary for AI systems. For every plan, including free. One-time €0.99, no subscription.
The llms.txt standard — introduced by Jeremy Howard (Answer.AI) in September 2024 — lets organizations provide a structured Markdown file at /llms.txt. This file guides AI language models to an organization’s most authoritative content, much like robots.txt does for search-engine crawlers — but purpose-built for the AI inference context. Full specification →
How AI systems like ChatGPT, Gemini & Perplexity read websites — and why the llms.txt standard decides your visibility.
Six industry templates following the official standard — copy, adapt, upload.
Every listing gets a personal AI Impact Score from 0 to 100. We check the availability, structure and content of your llms.txt, show you exactly what to improve, and re-check automatically on a regular basis — so you notice immediately if something breaks.
Which problems does llms.txt solve?
Classic websites hand AI systems a raw mix of navigation, ads and body text — llms.txt distills what matters.
Deeply nested HTML is hard for language models to parse. Markdown is the native language of LLMs.
Dynamically loaded content or JavaScript-generated text stays hidden from AI systems without a structured pointer.
Large websites quickly exceed an LLM’s processing capacity — llms.txt provides a clear, prioritized distillate.
What goes into an llms.txt?
| Website name | An H1 heading with the name of the organization or website |
| Short description | 1–3 sentences: who you are, what you offer, for whom |
| Sections | Thematically organized sections with H2 headings, explanations and links to important pages |
| Page links | References to individual pages — optionally as separate .md files for deeper content |
Rule of thumb: main file < 10 KB · Markdown format · root directory (/llms.txt) · complemented by /llms-full.txt for full page details
Who benefits most from llms.txt?
Libraries, frameworks and APIs benefit enormously — AI assistants cite documentation straight from llms.txt.
Product categories, policies and USPs are reliably picked up by AI shopping assistants from structured files.
Courses, publications and resources become discoverable for AI queries and correctly citable.
Frequently asked questions
No — for simple websites with easily accessible content it isn’t mandatory. But as soon as you want to be cited in AI answers specifically, or you have complex content, llms.txt is the most efficient way to give LLMs the right information.
robots.txt controls which pages search-engine crawlers may not visit — a blocklist. llms.txt is the opposite: it actively tells AI systems what they should know — a structured, inviting content offering.
llms.txt is the compact version: concise, under 10 KB, optimized for fast inference. llms-full.txt contains the full content of all linked pages as a single document — for AI systems that can or want to go deeper.
No — and Google now says so itself. Its official guide to generative AI features in Google Search (May 2026) states plainly that additional machine-readable files "neither harm nor help your site's visibility or rankings". The value of llms.txt lies elsewhere: with the systems that actually fetch it — Anthropic, OpenAI, Perplexity and Mistral all serve their own developer docs as an llms.txt — and in the structural discipline a good llms.txt enforces. Current status per system: llms.txt support status.
Recommended: review it at least every 3 months and update it immediately when your offering changes significantly. Outdated llms.txt files can cause AI systems to cite wrong or stale information.

How we verify authenticity: Only businesses with an existing directory entry can submit a review — either signed in to the customer portal or via a personal link we send to the email address stored with that entry. One review per entry. Before publishing we check each review for authenticity and legal violations — not by star rating; we do not filter out negative reviews. We neither buy nor pay for reviews. The average covers all published reviews.
