Every website is your design playground.

Inspect any live page like a design file. Tweak it in place, check it for accessibility and usability, and send your coding agent the exact change.

  • Free to start
  • Runs locally
  • No account needed

From “how did they build that?”
to a change you can see.

  1. 01Inspect

    Inspect it like a design file.
    Change it where it lives.

    Click anything on a live page. Read its measured values, then change them in place.

    • Measured type, color, spacing and contrast
    • Rewrite text, resize, move, duplicate
    • Spacing per side, row or column, full width or fit
    img · 307 × 230 → 307 × 264
  2. 02Responsive

    Every width, side by side.
    Scrolling together.

    See every device size at once.

    • Up to six devices, side by side
    • Scroll one and all follow
    • Real layout and media queries
    1280 → 768 → 390 → 375
  3. 03Localize

    Ship it in Arabic.
    Check it first.

    Open the site’s Arabic version, then check how it holds up.

    • Uses the site’s own language version when it has one
    • Mirrors the layout when it doesn’t
    • Checks direction, clipping and fonts
    lang="ar" dir="rtl"
  4. 04Extract and Audit

    Read it as a system.
    Then audit it.

    Values read from the rendered page. Findings checked against WCAG 2.2 and the ten usability heuristics.

    • Colors, fonts, assets and tokens in seven formats
    • HEX, RGB, HSL or OKLCH, in px or rem
    • A free audit: preview fixes, export PDF or Markdown
    --color-accent: #2554C7;
  5. 05AI mode

    Ask about anything on the page.
    With your own AI.

    Pick an element and ask. Its measured styles go along as context.

    • Paste a key, or use your own server
    • Pin comments or paste a screenshot, then ask
    • The answer changes the page, with one Undo

Your turnTry it on three example sites

Enough watching.
Make your move.

Three example sites with the real toolbar on top. Click anything to change it, press K to scale, or open any tool. Each change is written below as code.

Your edits, as code

    Change something above and it shows up here.

    Inspecting needs a mouse or trackpad, so on a phone this demo is a preview. Open this page on a computer to select and edit the example site, or add the extension to try it on any site.

    The extension’s real tools, on example sites. Nothing is sent, and edits reset when you reload.

    Pick your role.
    See what you take away.

    Turn a reference into a decision.

    • Read real type, color, spacing and radius values instead of eyeballing a screenshot.
    • Check contrast on the element, then try a better value on the live page.
    • Compare responsive states before the handoff.
    • Copy an element from one site, paste it on another, and match its style in one click.

    Start from measured values.

    • Export tokens in seven formats, in your colors and units.
    • See the technologies a site uses, and download its assets.
    • Copy a prompt written for your coding agent: Claude Code, Cursor, Codex, Copilot and more.
    • Copy the working code of any element, with notes on what the page does with it.
    Open the tokens in the playground

    Make the review something you can see.

    • Audit a page against WCAG 2.2 and the ten usability heuristics; each finding is linked to its element.
    • Preview a fix on the page before anyone writes a ticket.
    • Turn the finding into a prompt for the tool your team already uses, or share the report as a PDF.

    What does the extension analyze?

    Visible page structure, colors, typography, spacing, radii, shadows, visual assets, design tokens, technology signals, and detectable UX and accessibility concerns, the ten usability heuristics, and loading and stability measured on the page you have open. Results depend on what the browser can access: a very large page is read from its first 1,200 elements, and frames from other sites aren’t read. The extension says so wherever this applies.

    Can I edit websites?

    Yes. The live inspector supports temporary, browser-side visual experiments. It does not change a website’s server, repository, or published content. Playground changes are contained in this page and reset on reload.

    Can I copy an element from one site to another?

    Yes. Copy element takes one element, with its look, from a site you open with Inspect, and Paste element puts it on another site, in your tab only. One click makes the paste take on that site’s colors, type and buttons, and another brings back the style it was copied with. Copy code gives you the element’s working HTML and CSS instead, with notes on what the page does with it. Nothing leaves your device.

    Can I generate a prompt after editing the site?

    Yes. Prompt from edits, in the panel, lists each change you made with the inspector, before and after, written for the AI tool you choose. In the playground it reads your edits to the example sites.

    Can AI change the page for me?

    Yes, in your tab, never on the site itself. With your own key (Anthropic, OpenAI or Google Gemini) or your own server, pin notes or pick an element and ask. Your AI’s edits apply at once and one Undo reverts them all; it asks first when more than 10 elements would change or content would be hidden. If a model is busy, another from your key answers, and the answer says which. Copy as CSS or Create prompt takes the change to your code. Where your provider lists prices, Settings can limit AI to free models, and for OpenRouter it can ask for providers that don’t keep what you send, which leaves fewer free ones. Page details go only to the provider you choose, after you confirm. The playground here sends nothing: it previews the answers locally.

    Which browsers and languages does it support?

    It is made and tested for Google Chrome 116 or later on a computer. Other Chromium browsers that install extensions from the Chrome Web Store may work but aren’t tested. Firefox and Safari aren’t supported. The interface is in English and Arabic (right to left).

    Is it free?

    Yes. Everything on this page is free today, including AI mode and Audit with AI on your own key or server. Our AI, which needs no key, is coming soon.

    What does the extension send, and can I turn it off?

    Anonymous usage counts are on by default, after a notice: which features you use, never URLs, page content or what you type. Switch them off in Settings, under Privacy. With Your AI, your message and the context you keep on go straight to your provider, only when you send. The privacy policy has the details.

    Does the accessibility audit guarantee compliance?

    No. Each finding is checked against a WCAG 2.2 criterion or a usability heuristic and linked to its element, but automated findings are assistance, not certification. Manual testing, assistive-technology testing, and contextual human review are still needed.
