# llms.txt Generator

> What the llms.txt Generator does: build a structurally valid llms.txt for AI context, validate an existing one live, with examples and a format reference.

## A file that explains your website to AI systems

An `llms.txt` is a small Markdown file in your domain's root — reachable at `https://yourdomain.com/llms.txt`. It does for AI language models what `robots.txt` does for crawlers: it gives them a **curated, accurate entry point** into your content. Instead of blindly grazing a whole site, an AI system reads the `llms.txt` like a table of contents and uses it to decide which pages to fetch at all. The [llms.txt Generator](https://www.jpkc.com/tools/llms/) builds exactly that file for you — and validates an existing one on request.

The problem it solves: `llms.txt` is Markdown with a **fixed but easy-to-miss structure** — an H1 title, a blockquote tagline, thematic sections, link lists with descriptions. Done by hand it's error-prone, and a single structural slip (missing tagline, empty URL, everything dumped into one section) devalues the file for the AI. The generator takes the syntax off your hands: you fill in a form, and the tool writes the correct Markdown live as you type.

The tool is for everyone who wants AI systems to capture and cite their site **correctly**: **developers** giving their docs or project site a clean `llms.txt`; **content and SEO people** who want to stay visible in generative search (GEO); and anyone who needs to quickly check a third-party or their own `llms.txt` for validity. Everything runs in the browser — no account, no installation.

## What the tool does

The llms.txt Generator has five tabs (the interface is in English):

- **Generator** — the core: a form for name, tagline, intro, sections, links, and subsections. The tool builds the finished `llms.txt` Markdown live in an editor on the right. **Copy** it to the clipboard, **Download** it as an `llms.txt` file, or use **Open File** to load an existing file back into the form for editing.
- **Check** — the **live checker/validator**: enter a domain (`example.com`, `/llms.txt` is appended automatically) or a full URL, and the tool fetches the file and checks it **against the llmstxt.org specification**. You get required errors, warnings, and hints separately, plus a summary (title, tagline, number of sections and links, file size).
- **Examples** — four real-world templates (open-source library, SaaS product, blog, docs site) you load into the generator with one click and adapt.
- **Tips** — best practices: what makes a good `llms.txt`, what to avoid, where the file goes, and how big it may be.
- **Reference** — the complete **format reference**: a full example, a field table (which element uses which syntax, what's required and what's optional), and the explanation of `llms-full.txt`.

## All in the browser — the generator needs no server at all

The **generator** works entirely client-side: as you type, JavaScript assembles the Markdown, the editor shows it live, and your work in progress is saved locally in the browser (LocalStorage) — so it's still there on your next visit. Nothing leaves your machine.

Only the **Check** tab needs the network, because for security reasons your browser cannot fetch a third-party `llms.txt` directly (CORS). So a **server-side JPKCom proxy** retrieves the file and hands it back to your browser for validation; the actual checking again runs locally on your machine. The checked domain therefore sees a request from the JPKCom server, not your IP; internal and private addresses are blocked server-side. The two PHP endpoints behind this are **not a public API** — they're hardened exclusively for the tool.

## Try it now

**[→ Open the llms.txt Generator](https://www.jpkc.com/tools/llms/)** — fill in the form, read along as the Markdown builds live, download it, and place it in your web root. Or check an existing `llms.txt` in the **Check** tab. No account, free, right in the browser. If you'd like to see what a good file looks like first, the four templates in the **Examples** tab load ready-made structures into the generator.

## Related JPKCom tools

The `llms.txt` is one building block of AI/GEO optimization — these tools complement it:

- **[SEO & GEO Analyzer](https://www.jpkc.com/db/en/tools/seo/)** — inspects a whole page and rates the `llms.txt` as part of the **GEO score** (the `llms.txt Present` and `llms.txt Valid Structure` checks). Here you build the file; there you see how it feeds into the page's AI readiness — both tools use the same validator logic.
- **[Meta Tags Generator](https://www.jpkc.com/db/en/tools/meta-tags/)** — clean titles, descriptions, and Open Graph/Twitter data that, alongside the `llms.txt`, also count in the GEO score.
- **[robots.txt & Sitemap](https://www.jpkc.com/db/en/tools/robots-sitemap/)** — build crawling rules and sitemap entries, including allow-listing AI crawlers.
