Google Says You Don't Need llms.txt. Here's the Catch.
Google says llms.txt is unnecessary. Chrome Lighthouse audits it anyway. We fact-checked five studies on what llms.txt really does for AI visibility in 2026.

Free brand check
AI is already talking about your brand.
Radar fixes what it's saying.
Most sites were built for Google, not for how AI reads the web, so engines misread your brand, cite the wrong facts, or skip you. Radar audits why and hands you the exact fix for each issue. Free to start, first audit in 60 seconds.
Every reason AI gets you wrong, in one audit.
Radar runs 13 checks in parallel across the full AI visibility stack, from crawl access and schema to live hallucination detection and share of voice across ChatGPT, Claude, Gemini, and Perplexity.
Find what no single tool can see
Blocking AI bots but expecting citations? Good crawlability but no llms.txt? Radar surfaces cross-tool conflicts no individual check would catch. This is the insight you cannot get from running 13 tools separately.
13 tools, one audit
Crawl check, robots.txt, llms.txt, AI readiness, citations, Reddit, AEO, citation test, source influence, SOV, schema audit, hallucination check, and brand disambiguation. All run in parallel.
One audit covers everything AI reads, from crawl access to hallucination detection.
6 technical readiness tools run free on every check. The 7 AI-response tools (citations, Reddit, hallucination, SOV, source influence, citation test, brand disambiguation) unlock with any paid plan.

Every issue comes with the exact fix, pre-written for your domain.
Radar doesn't just score you. It generates a context-rich AI prompt for every finding, pre-filled with your audit data, ready to paste into Claude, ChatGPT, or Cursor.
AI Prompt Generator
Every action item generates a context-rich prompt pre-filled with your audit data: your blocked bots, missing schema types, citation rates, and domain. Copy it into Claude, ChatGPT, or Cursor and implement the fix. Includes llms.txt and schema markup generators.
Implementation Threads
Actions group into 5 structured fix threads: Crawlability, Structured Data, LLM Communication, Content Authority, and Citation Building. Follow them in order, check off steps as you go, progress saved across sessions.
Re-verify and Track
Re-run any single tool to verify your fix worked. Fix your robots.txt and re-check just the Crawl Check in 15 seconds, no need to re-run all 13 tools.

Why we built this
We were invisible to AI. So we built the tool that fixed it.
In October 2025, ChatGPT was hallucinating about our services. Perplexity didn't know we existed. Over 6 months and 516 commits, we fixed every AI visibility issue manually. Then we packaged those fixes into Radar so you don't have to.

Frequently asked questions
Is Radar really free?
Yes. Your first full 13-tool audit is free with no credit card. Includes all DIY features: implementation threads, AI prompt generator, llms.txt generator, and schema markup generator. Need more audits? Audit packs start at $5, or Pro Retainer $199/mo for 40 audits plus weekly pulse re-scan. See pricing at pixelmojo.io/platform/pricing.
What tools are free vs paid?
Free (6 tools): AI bot crawl check, robots.txt analyzer, llms.txt validator, schema markup audit, AEO page auditor, AI Readiness score. Paid (7 more): citation tracking across ChatGPT/Claude/Gemini/Perplexity, Reddit brand monitoring, hallucination detection, prompt SOV, source influence mapping, answer engine per-page testing, and brand disambiguation.
How long does an audit take?
About 60 seconds for individual tool runs. Full 13-tool audits run all tools in parallel and typically finish in 1-3 minutes depending on your site complexity and how quickly each LLM responds. Free audits run 6 technical readiness tools and complete faster. Results stream in as each tool completes, so you can start reading without waiting for the slowest one.
How is Radar different from Semrush or Otterly?
Semrush and Otterly are monitoring tools that track brand mentions over time. Radar is a DIY audit-and-fix platform: deep technical scan across 12 dimensions, plus AI-ready implementation prompts for every issue it finds. Most teams use Radar to audit and fix, then a monitoring tool to track changes.
What if I want someone to implement the fixes?
Start with Radar DIY: the implementation threads and AI prompts handle most fixes. For complex strategy or ongoing optimization, we offer an AI Visibility Strategy service ($4,500 sprint + retainer) where our team handles everything.
Why should I trust Radar?
We built Radar for ourselves first. In October 2025, AI was hallucinating about our own brand. We spent 6 months and 516 git commits fixing our AI visibility manually, then automated those fixes into Radar. Every feature maps to a real problem we hit. Read the full origin story at pixelmojo.io/blogs/ai-visibility-stack-origin-story.
Can I verify my fixes without a full re-audit?
Yes. Every completed tool has a Re-verify button. Fix your robots.txt and re-run just the Crawl Check in 15 seconds. No need to re-run all 13 tools.
What AI engines does Radar query?
Radar queries ChatGPT, Claude, Perplexity, and Gemini directly for citation tracking, share of voice, and hallucination detection.
What are implementation threads?
Radar groups your action items into 5 structured fix threads: Crawlability, Structured Data, LLM Communication, Content Authority, and Citation Building. Each thread has ordered steps with AI-ready prompts. You follow them in sequence, checking off steps as you go, with progress saved across sessions.
Find what AI gets wrong about you, free.
Run a free check across 6 technical readiness tools and preview all 13. Unlock the 7 AI-response tools and every fix prompt for $5.
