GEO Content Similarity Checker

In GEO, similarity isn't just a plagiarism problem — it determines whether AI platforms see your content as a unique, citable source or just another copy of what already exists. Choose your check type below.

What do you want to check?
🤖 AI Answer vs My Page Compare an AI response to your content. Find what AI says that you don't.
🏆 My Page vs Competitor Compare against a page AI frequently cites. Find what makes them more citable.
🔄 Two of My Own Pages Check if two pages on your site are too similar — cannibalisation risk.
📋 Pre-Publish Check Check a new article before publishing. Ensure it's unique enough to be citable.
How to use: Go to ChatGPT, Gemini, or Perplexity and ask the question your page should answer. Copy the full AI response and paste it in the left box. Paste your page content in the right box. The missing words are your GEO gap.
AI-Generated Answer Paste the response from ChatGPT, Gemini, Perplexity, or Claude
Your Page Content Paste your article, landing page, or blog post
