Browser extension — check any page’s AI visibility on the spot

Can AI search — ChatGPT, Gemini, Perplexity, AI Overviews — actually read the page you have open? Does it cite you? The extension answers where you already are, without leaving the page.

Install

Add from the Chrome Web Store

It is free. Add it from the Chrome Web Store and it works immediately, with no sign-up. Brave, Vivaldi, Arc and Opera install from the Chrome Web Store too.

How to use it

  1. 1 Add the extension Press “Add to Chrome” in the Chrome Web Store. It asks for activeTab, storage and scripting — and nothing that reads “access to all sites”.
  2. 2 Click the icon on the page you care about Your page or a competitor’s, it makes no difference. Click the Suparanku icon in the toolbar and choose “Check this page”.
  3. 3 Read the verdict right there A panel opens in the top-right with the quick score and all 24 checks, worst first. Click any row to see what that check actually looks at.
  4. 4 Sign in to overlay your own data Sign in and allow your brand’s domains, and on those domains simply opening a page shows SRPS, AI citations and the recommendations for it.

What it does without an account

The check runs entirely inside your browser. It reads the HTML of the page in front of you and makes no network request at all.

  • Title, meta description, canonical, indexability, JSON-LD structured data, Open Graph tags, heading hierarchy, author and freshness signals (E-E-A-T), image alt coverage, mixed content — 24 checks in total.
  • The quick score uses the product’s own formula and weights. Because its evidence is limited to the HTML, it is deliberately never called SRPS.
  • It behaves the same on your pages and on a competitor’s. The other site learns nothing.

If you already have an account — the deep audit, on the spot

If you already use Suparanku, then on your own brand’s domains the panel stops estimating and shows the real audit: the deep-audit checks no browser-side script can compute, for the exact page you have open, without a trip to the dashboard.

  • Not the 24 local checks but every check for that page — fast and deep, with priorities: the rendered page rather than its source HTML alone, content depth and uniqueness, the answer capsule, scannability, whether claims cite their sources, Core Web Vitals.
  • The Suparanku Page Score (SRPS) for that URL, the issue count (total and high priority) and the link-health summary.
  • How many times AI assistants cited the page, and when the data was last fetched.
  • The technical recommendations tied to that page, and a link to its full report.
  • On the Free plan you see the snapshot from your first audit (Free has no re-scan).

The 24 checks

These are the same checks as in the dashboard — same names, same verdicts — so a finding in the extension is one you can follow straight into the report.

Core meta and indexability

  • Title tag
  • Meta description
  • Canonical
  • Indexable
  • HTML lang
  • hreflang
  • Viewport (mobile)
  • Charset declared

Headings and document structure

  • Single H1
  • Heading hierarchy
  • Semantic HTML5

Structured data

  • Structured data
  • Schema type matches page
  • Breadcrumb

Trust and freshness (E-E-A-T)

  • Author & E-E-A-T
  • Freshness
  • Year in title / H1

Sharing preview (Open Graph / Twitter Card)

  • og:title / description
  • og:image present
  • og:type / og:url
  • OG language match
  • Twitter Card

Other quality signals

  • Image alt coverage
  • No mixed content

Checks that do not apply are dropped from the list and from the denominator. A single-language site having no hreflang is not a defect.

What a local check cannot see

A browser-side check only ever sees the HTML. The following need a crawl and real measurement across the whole site — that is the free AI brand audit.

  • HTTP status, robots.txt, llms.txt, sitemap coverage, link health.
  • The rendered DOM and Core Web Vitals.
  • Whether AI assistants actually cite this page, and how often.
  • How competitors look on the same questions, and your relative position across the five axes.

Permissions

  • Installing asks only for activeTab, storage and scripting. It never asks for access to all sites.
  • Standing access to your own domains is granted per domain after you sign in, from a list you can see.
  • Any grant can be revoked at any time from the browser’s extension settings.

The exact score comes from the free AI brand audit

The extension’s quick score is an estimate from the page’s HTML alone. The accurate site-wide diagnosis, measured AI citations and the comparison with competitors are part of the free plan.

Privacy

Without an account, nothing is sent anywhere. Signed in, only the origin and path of pages you open on your allowed domains go to app.suparanku.com — the query string and fragment are stripped inside the extension. Data is stored in the Tokyo region. The handling is set out in section 6-3 of the privacy policy (browser extension).
