AI systems don't search your whole page at once. They cut it into pieces first, then only use a piece if it reads as complete on its own — so if a heading and its full answer don't fit in the same piece, the AI may just skip it instead of using half of it.
Paste your page's URL below and we'll show you exactly where those cuts would land.

No — this checks one structural signal Prompt Fit also looks at: whether a section is short enough to be pulled out as one self-contained chunk. It can't tell you whether the answer itself is correct, well-written, or reachable by AI bots — that needs Prompt Fit reading your live URL. See what Prompt Fit checks for the full picture.
Everything from one heading up to the next heading, including the heading itself. That's the same rule our own analysis pipeline uses to break a page into sections before checking it.
Retrieval chunk sizes vary by AI system, typically landing somewhere between roughly 256 and 800 tokens. We flag at the low end of that range, so a flagged section risks being too long even for the smallest common chunk size — a conservative warning, not a guarantee it will be ignored.
If your headings or text are injected by client-side JavaScript after the page loads, this tool won't see them, the same limitation a lot of retrieval crawlers have. Content Visibility checks the rendered version against the raw HTML to catch that gap.
Any page you want an AI assistant to cite — a product page, a pricing page, a detailed guide. Long-form pages with several headings are the most likely to have at least one section running long.
No — we fetch the page through a lightweight proxy so your browser can read it without hitting cross-origin restrictions, then everything is parsed and counted locally. We don't store the HTML or your results. See our privacy policy for details.
