Free llms.txt Generator

An llms.txt manifest tells ChatGPT, Perplexity, Claude, and Gemini which pages on your site to ground citations against. Sites with a valid /llms.txt show a 0.55 correlation with AI-citation probability (Princeton 4-factor GEO framework). Build yours in 90 seconds.

Site Name (H1)

Canonical Site URL

Summary (1-3 sentences)

## Docs

Canonical answer pages — your most authoritative, evergreen content.

## Examples

Worked examples, case studies, demos — concrete things models can cite.

## Optional

Supporting context that helps but is not required for grounding.

Spec Readiness

Site name (H1) is empty — required by the spec.
Add a canonical site URL (used as the > blockquote).
Summary is short — aim for 40+ characters so models know what your site is for.
Add at least one entry under Docs — this is the primary grounding section.
Add at least 3 valid links — sparse manifests get ignored by retrievers.

# Your Site

What

A plain-text Markdown file at /llms.txt that lists your most authoritative pages, organized into Docs, Examples, and Optional.

Why

Retrieval-augmented LLMs (Perplexity, SearchGPT, Gemini) face a context-window budget. llms.txt tells them which URLs to prioritize when grounding answers about your site.

How

Pick 6-12 pages that are self-contained and answer real questions. Skip your homepage, about page, and category indexes — they don't carry standalone meaning.
