The Problem
AI search engines like ChatGPT, Perplexity, Claude, and Gemini are becoming how people discover products and services. But most websites are completely invisible to them — and their owners have no idea.

What It Checks

- Schema Markup — Do you have FAQ, HowTo, or Product structured data that AI can extract?
- Content Structure — Is your content formatted so AI can understand and cite it?
- Technical Setup — HTTPS, sitemaps, response time, and crawlability

Hey Uneed!

I'm excited to introduce llms-txt.io today, the #1 llms.txt file generator.

❓ WHAT IS LLMS.TXT?

AI systems like Claude and ChatGPT are becoming more and more important for retrieving information from websites.

But, these systems often struggle to understand website structure and content due to limited context windows.

llms.txt solves this by providing a standardized way for websites to present their content in an AI-friendly format — think of it as robots.txt but specifically designed for large language models.

🔑 LLMS-TXT.IO

Our free generator makes it easy (and free) to create these files for any website.

Just enter your URL, and we'll generate both the basic navigation structure (llms.txt) and full content version (llms-full.txt).

❤️ YOU

We would love your support, feedback and questions!

Keytail is a Growth Automation Engine that turns long-tail questions into published, brand-consistent content — automatically.

Most brands are invisible inside AI. When someone asks ChatGPT, Perplexity, or Gemini for a recommendation in your space, you're not there. Not because your product isn't good — but because you don't have the structured, high-quality content those systems pull from.

Keytail fixes that.

It runs the full pipeline for you:

Discover — Finds the exact long-tail questions your audience is already asking across Google and AI search engines.

Create — Generates SEO and AEO-optimized articles structured to be the best answer on the internet for each query. Not generic AI writing. Intent-driven, schema-ready, metadata-complete content.

Design — Produces branded thumbnails automatically. No Canva. No designers. Every article ships with a brand-aligned visual.

Publish — Connects directly to your CMS (Webflow, WordPress, Sanity). One click. No copy-pasting, no manual uploads.

Repurpose — Turns every article into LinkedIn posts, Instagram carousels, reel scripts, X posts, and Threads content. One asset becomes twenty.

The result: a compounding content engine that makes your brand discoverable — on Google today, and inside AI answer engines tomorrow.
