The Free AEO Checker That Scores Your Content for AI Search
An AEO checker is a tool that scores how well your content is optimized for AI answer engines like ChatGPT, Perplexity, and Google AI Overviews. Peplio’s free AEO checker grades your article across 8 ranking factors and tells you exactly what to fix — before you publish.
Most answer engine optimization tools only audit a live URL after it’s already published, and many hide the real insights behind a paywall. Peplio’s tool works differently. It’s a genuinely free AEO checker that scores your draft — paste your text, get an instant score out of 100, and see precisely which signals are helping or hurting your chances of being cited by AI.
It also doubles as a generative engine optimization tool: alongside the score, it runs a real Google Gemini AI citation test on your content and can automatically rewrite your weakest sections for AI search. Whether you’re a blogger, SEO specialist, or small business owner, you get a clear, actionable picture of how AI-ready your content is — completely free, with no signup.
How to Use the AEO Checker — Step by Step
Copy your blog post or article into the box — up to 5,000 words. It works on unpublished drafts too, so you can optimize before the content ever goes live.
The AEO checker instantly analyzes your text across 8 factors — direct answers, statistics, structure, FAQ, authority, citations, entities, and readability — and gives you a score out of 100.
See your full breakdown, your AI-engine compatibility for ChatGPT, Perplexity and Gemini, and a prioritized list of the exact changes that will improve your score the most.
Run a real Gemini citation test, then let the AI rewrite your weakest sections — optimized for AI search. Re-score the improved version to confirm the gain.

What Is AEO — and How Is It Different From GEO and SEO?
AEO (Answer Engine Optimization) is the practice of structuring your content so AI answer engines — ChatGPT, Perplexity, Google AI Overviews, and Gemini — cite it when answering user questions. Where traditional SEO aims to rank a page in a list of blue links, AEO aims to make your content the actual answer the AI gives.
GEO (Generative Engine Optimization) is the content-structuring methodology within AEO — the specific techniques that make generative AI models more likely to reference your content. In practice the two overlap heavily, which is why Peplio works as both an AEO checker and a generative engine optimization tool: it scores the exact signals (direct answers, entities, citations, structured data) that determine whether AI engines trust and quote your content. To rank in AI search, lead each section with a direct 40 to 60 word answer, back claims with statistics and named sources, use clean headings and FAQ schema, and reference specific entities. The AEO checker scores all of these automatically.
How the AEO Checker Works
The tool runs in two layers. First, the moment you paste your draft, an 8-factor scoring engine analyzes your content directly in your browser — no waiting, no data sent anywhere. It checks for a direct answer in your opening, the density of statistics and named sources, your heading and list structure, FAQ and schema signals, author authority, external citations, named entities, and readability. Each factor is scored and combined into your overall AEO score out of 100, with a prioritized list of fixes.
Second, the optional AI citation test is powered by the Google Gemini API, which we’ve integrated directly into the tool. When you enter a target query, your content is sent securely to Google’s Gemini model, which evaluates how likely an AI answer engine is to cite your content for that query and returns a citation-likelihood score with specific reasoning. The same Gemini integration powers the Fix with AI feature, which rewrites your weakest sections — your opening, your FAQ, or the whole article — optimized for AI search. Because the core scoring runs locally and only the AI features call Gemini, the tool stays fast and free for everyone.
