Humans vs LLMs

See your webpage the way ChatGPT, Gemini, and Claude read it. Spot content that is missing, inaccessible, or hidden from AI.

Preview only—some interactive elements may differ from the live page.

What the Comparison Reveals

  • JavaScript-only content

    See browser-rendered content that may be missing from the HTML available to AI crawlers, including dynamic product lists, reviews, and injected copy.

  • Missing alt text and ARIA labels

    Find images, icons, and buttons that lack the labels AI systems and assistive technology rely on.

  • Broken semantic structure

    See where incorrect headings, sections, and landmarks flatten the page hierarchy and make the content harder to interpret.

  • Decorative markup

    Strip away styling, shadows, and background images to reveal the content and structure that remain readable.

  • Low content-to-code ratio

    Spot excessive wrappers and nested markup that bury the page's useful content.

  • Hidden or deferred elements

    Identify text and controls that are hidden, deferred, or absent from the page's initial HTML.

BEHIND THE COMPARISON

How the Humans vs LLMs preview works

A simpler view of your page helps you inspect its text and labels. It is a visual simulation, not a live ChatGPT, Gemini or Claude response.

  1. Fetch the page

    We request the page HTML and attempt a JavaScript-rendered snapshot. The preview uses rendered HTML when available, with the original HTML as a fallback.

    One captured page
  2. Simplify the presentation

    The simplified view removes decorative styling and replaces larger images and controls with text placeholders, using available alt text and control labels.

    Text and labels in focus
  3. Compare the views

    Both views start from the same captured HTML. Look for missing labels and content that depends on visual presentation, then check the finding on your live page.

    A visual diagnostic

Same content. A different presentation.

Illustrative example, not a scan of a real website.

The image’s HTML includes alt="Blue backpack with side pockets".

Alt text supplies the image label. The heading and copy remain; the button becomes a text placeholder.

What to look for: useful labels and meaning that survive the simplified presentation. A missing label is a prompt to inspect your HTML, not proof that every AI system sees this exact view.

Questions about the preview

Is this exactly what ChatGPT, Gemini or Claude sees?

No. Humans vs LLMs is a visual simulation of a simplified webpage, not a response from those assistants or a reproduction of every AI browsing pipeline. Different systems may fetch, render and interpret a page differently. It does not measure whether your page will be indexed, recommended or cited.

Does the tool use the original HTML or JavaScript-rendered content?

The tool requests the original HTML and attempts a JavaScript-rendered snapshot. It uses the rendered HTML when available and falls back to the original HTML if rendering is unavailable. Both preview views use the same selected snapshot; they are not a separate raw-versus-rendered HTML comparison.

What changes in the simplified view?

The preview removes page scripts, embedded frames and common modal or popup elements. The simplified view also resets fonts, backgrounds, shadows and colors, and replaces larger images and form controls with text placeholders. Available image alt text and control labels help describe those elements. This is a presentation transformation, not an AI interpretation of each image.

Does missing content prove that AI cannot read it?

No. Rendering failures, short capture timing, preview cleanup and content loaded only after an interaction can affect the result. A styled-versus-simplified preview alone does not prove that JavaScript content is inaccessible to every AI crawler. Check your live page, its HTML and the relevant crawler documentation before deciding what to change.

How should I use the comparison?

Use it to spot missing image descriptions, unclear control labels and information that relies on visual styling. Check those findings on the live page and improve the underlying HTML where appropriate.
