IndexDecode
Check if AI crawlers can find, read, and cite your site
Free diagnostic that checks 30+ AI crawlers and 70+ Google indexing signals on any URL. See if ChatGPT, Claude, and Perplexity can actually reach your content — with platform-specific fixes for Next.js, WordPress, Shopify & more.
I built IndexDecode because I kept running into the same problem: sites that rank perfectly on Google are invisible to ChatGPT, Claude, and Perplexity.
Google executes JavaScript. Most AI crawlers don't. Google reads your sitemap. AI bots may not even check robots.txt. The rules are completely different, and there wasn't a single tool that checked both worlds together.
Most "AI visibility" tools ask ChatGPT "do you know this brand?" and count mentions. That's brand monitoring — useful, but different.
IndexDecode checks the TECHNICAL layer: can AI crawlers actually reach your page? Can they extract meaningful content from it? Is your content structured so AI can cite you with attribution?
That's our three-layer framework:
Access — Can AI bots technically reach your content?
Extractability — Can they understand what they find?
Citability — Can they quote and attribute it to you?
What's free (everything):
Single page scans — unlimited, no signup
30+ AI crawlers checked (GPTBot, ClaudeBot, PerplexityBot...)
70+ Google indexing checks
Platform-specific fixes (not generic — actual Next.js/WordPress code)
Export to PDF, HTML, Markdown, JSON
12 standalone tools (robots.txt checker, meta tags, redirects...)
What Pro adds:
Site Scanner: scan 25+ pages from your sitemap at once
"Fix Once, Fix Everywhere" — finds template-level issues that one code change resolves across your entire site
LLM-generated action plans
Score tracking over time
I'm a senior data engineer by day, building this nights and weekends. The whole thing runs on Supabase + Lovable.
Would love your honest feedback — and if you scan your own site, share your scores in the comments. I'm genuinely curious what people find.

Who hunted IndexDecode?
IndexDecode was hunted by Ramkumar Perumal.

Hey PH! I'm Ram 👋
I built IndexDecode because I kept running into the same problem: sites that rank perfectly on Google are invisible to ChatGPT, Claude, and Perplexity.
Google executes JavaScript. Most AI crawlers don't. Google reads your sitemap. AI bots may not even check robots.txt. The rules are completely different, and there wasn't a single tool that checked both worlds together.
So I built one.

Most "AI visibility" tools ask ChatGPT "do you know this brand?" and count mentions. That's brand monitoring — useful, but different.
