What is an llms.txt file?

/llms.txt is an emerging standard — a plain-text introduction file at yourapp.com/llms.txt that gives AI a clean, curated summary of what your app is and which pages matter, like a short 'about us' an AI reads first. It follows the llmstxt.org shape: an H1 with your app's name, a blockquote summary, then sectioned lists of key pages. Most vibe-coded apps don't have one yet, which makes publishing one an early-mover edge.

A good one follows the llmstxt.org shape — this is the pattern getAdvantage publishes for itself at getadvantage.app/llms.txt:

# Your App Name

> One-sentence summary of what your app does and who it's for.

## Key pages

- [Home](https://yourapp.com/): What the app is.
- [Pricing](https://yourapp.com/pricing): Plans and prices.
- [Docs](https://yourapp.com/docs): How it works.

How to add an llms.txt to your app

1. Generate — paste your URL above. The tool reads your page and drafts a starter llms.txt from its own title, summary and headings.
2. Review and copy— tighten the summary and the key-page list so they read the way you'd describe your app, then copy or download the file.
3. Publish — serve it at yourapp.com/llms.txt as text/plain. On Lovable, Bolt, v0, Base44 or Replit, paste the contents and ask your builder to publish a file at that path.

Where do I put the llms.txt file?

Serve it at the root of your domain — yourapp.com/llms.txt — as plain text (content-type text/plain), so AI crawlers read it as a real file rather than an HTML shell. On Lovable, Bolt, v0, Base44 or Replit, paste the generated contents and ask your builder to publish a file at that exact path.

Will an llms.txt get my app recommended by ChatGPT?

An llms.txt makes your app more legible to AI — necessary, but not sufficient on its own. Being recommended also takes machine-readable facts (JSON-LD), a clean heading structure, AI crawlers allowed in robots.txt, and real web presence over time. The generated file is an honest starting point you should review and tighten — it improves how assistants can read you; it can't guarantee any assistant's answer.

How is this different from getAdvantage's full scan?

This tool does one thing: generate a starter llms.txt. The full getAdvantage scan measures all nine AI-readability signals an answer engine reads (title, meta, JSON-LD, headings, llms.txt, content ratio, Open Graph, canonical, AI-crawler access), shows which competitors a ChatGPT-class model names instead of you, and hands you every remaining fix as a prompt you paste back into your builder.
