AI Grade Tool is a free content grading platform that scores any webpage 0–100 for AI citation readiness — measuring how likely that content is to be selected as a source by ChatGPT, Claude, Perplexity, Google AI Overviews, and Gemini. No account is required.
Why this matters
Search is changing. When someone asks an AI engine a question, the AI synthesizes an answer from a small handful of sources it considers high quality. Being one of those cited sources is the new equivalent of ranking on page one of Google. The signals AI engines use are different from traditional SEO, and most content on the web is not optimized for them.
AI Grade Tool analyzes content against six weighted criteria that influence AI citation likelihood: extractable claims, evidence density, entity clarity, passage independence, information structure, and freshness signals. The result is a score out of 100, the passage an AI is most likely to extract, specific gaps to address, and a rewritten opening optimized for citation.
How it works
Submit a URL or paste content directly. AI Grade Tool also checks four AIO signals — crawlability, schema markup, freshness, and answer clarity — that determine whether a page qualifies to appear in Google AI Overviews. The analysis takes about 10 seconds, results pages are permanent and shareable, and the analysis tools are free with no sign-up required.
Who built this
AI Grade Tool is an independent project built by a small team that believes writers and publishers creating original work should have free access to the same optimization tools that large SEO platforms charge thousands of dollars per year for. AI Grade Tool is funded by display advertising so its core analysis tools stay free for everyone.

Is AI Grade Tool free to use?+
AI Grade Tool's six analysis tools — GEO Score Checker, AIO Checker, Robots.txt Checker, Compare Pages, AI Keyword Finder, and FAQ Generator — are 100% free with no account or sign-up required. Advanced monitoring is paid: Pro ($9.99/mo) unlocks the Dashboard and Domain Monitor for daily score tracking, and Agency ($79.99/mo) adds Bulk Sweep for scoring up to 50 URLs at once.
What is a GEO score?+
A GEO score is a 0–100 rating that measures how likely a piece of content is to be cited by AI search engines. GEO stands for Generative Engine Optimization — the practice of structuring content so AI engines like ChatGPT, Perplexity, and Google AI Overviews select it as a source when answering user queries.
How is AI Grade Tool different from an SEO tool?+
Traditional SEO tools optimize for Google's ranking algorithm — keyword density, backlinks, and page authority. AI Grade Tool optimizes for AI citation signals: extractable claims, entity clarity, passage independence, answer clarity, structured data, and content freshness. These are the signals AI engines use to choose which pages to cite as sources.
What AI search engines does AI Grade Tool optimize for?+
AI Grade Tool optimizes for four major AI search engines: ChatGPT (OpenAI), Perplexity AI, Google AI Overviews, and Gemini. The GEO scoring criteria are weighted based on citation patterns documented across all four engines.
