The three problems
🔍

You’re not in the answer

When a potential customer asks ChatGPT “best [your service] in [your city]” you simply don’t appear. Your competitor does. Not because they’re better. Because their site is structured the way AI reads.

Symptom: declining inbound despite stable Google rankings

⚠️

The answer is wrong

AI is already talking about you. It has wrong opening hours. An outdated service list. A description that contradicts your homepage. Customers arrive with incorrect expectations — or don’t arrive at all.

Symptom: “I thought you were…” conversations increasing

📊

Your SEO spend isn’t transferring

Only 38% of top-ranked Google pages appear in ChatGPT responses. Backlinks, keyword density, page authority — near-zero correlation with LLM citation. The game changed. The tools didn’t.

Symptom: organic traffic flat despite top-10 rankings

How Legible works
01

Preview your score

Enter any URL above. Legible crawls your site and scores it on six dimensions LLMs actually care about: entity clarity, factual density, internal consistency, schema presence, freshness signals, and claim verifiability. Your grade appears instantly — free, no account needed.

Free — any URL
02

Get the fix list + llms.txt

Unlock the full report for a one-time $29: specific issues on specific pages, a prioritised fix list, and a generated /llms.txt file ready to deploy. One payment, yours forever. No subscription required to improve your AI visibility.

One-time — $29
03

Monitor weekly

AI models update constantly. A site that scored A in January can score C in March through no fault of its own. The Standard plan monitors ChatGPT, Claude, and Perplexity weekly — alerting you when your citation status changes or competitors overtake you.

What is an llms.txt file?

An llms.txt file is a short text document that lives at yoursite.com/llms.txt. It tells ChatGPT, Claude, Perplexity, and other AI assistants exactly who you are, what you do, and what you want them to know about your business — in a format they can read reliably. Think of it as a business card written specifically for AI. Without one, AI models piece together information from your general web pages and frequently get things wrong. Legible generates yours automatically. Here is ours as a live example:

Common questions
The free preview shows your Legibility Score (A–F), your six dimension scores, and one specific issue. The $29 one-time report unlocks all issues with page-level specificity, a prioritised step-by-step fix list, and your generated llms.txt file ready to deploy. No subscription — one payment, full access.
AI models update constantly — a site that scored A in January can score C in March through no fault of its own. Your own site also changes over time, and every content update is a potential visibility regression. Monitoring catches both: model-driven citation drift and self-inflicted regressions, before your customers notice.
Profound and similar tools tell you what AI says about your brand but give you no tools to fix it — $300+/month for a dashboard. Legible starts at $29 one-time and includes the full fix layer: llms.txt generation, Schema.org improvements, and accuracy verification. The only tool that actively prevents false or contradictory information from reaching AI models.
Yes — permanently. The full free tier including audit, llms.txt generation, and monthly monitoring is always free for nonprofits and educational institutions. Not a time-limited trial. Email hello@legible.ai to apply.
