One-click SEO audit, plus an AI visibility score

Citewren is a Chrome extension that checks the page you are on for classic on-page SEO and tells you whether AI engines such as ChatGPT, Perplexity, Gemini and Google AI Overviews can reach, understand and quote it.

Chrome Web Store listing coming soon. The Free plan needs no account.

Three audits in one click

All page checks run locally in your browser, only after you click the extension. Nothing is sent anywhere unless you use an AI-powered feature.

Frequently asked questions

What is the difference between SEO, AIO and GEO?

SEO is about ranking in classic search results. AIO (AI optimization) is about making a page easy for AI crawlers and large language models to fetch, parse and trust. GEO (generative engine optimization) is about how often AI engines such as ChatGPT, Perplexity, Gemini and Google AI Overviews mention or cite your brand in their answers.

Does the extension read every page I visit?

No. Citewren only reads a page after you click the extension on it, using Chrome's activeTab permission. It has no permanent access to your browsing.

Is my page content sent to a server?

Not for the SEO and AI readiness checks, which run entirely in your browser. Page text is sent to our server only when you start an AI-powered feature on a paid plan. See the Privacy Policy.

How do I activate a paid plan?

After checkout, Polar emails you a license key. Open the extension, click the plan button, and paste the key. You can remove it from the same place.

Can I cancel?

Yes, any time, from the link in your Polar receipt email or the Polar customer portal. Your plan stays active until the end of the period you paid for.

Which browsers are supported?

Google Chrome and other Chromium browsers that support Chrome extensions (Manifest V3).
