Polaris — X Profile Analyzer

Polaris gives you a complete analytical view of any X (Twitter) profile; instantly, privately, and without using X's API.

Visit any profile on X, click the Polaris icon, and get a full breakdown of the
account: follower trends, posting activity, engagement metrics, tweet analysis,
word clouds, and behavioural patterns. Everything is computed in real time from
publicly visible data on the page.

PRIVACY BY DESIGN

Polaris is built on a simple principle: your data stays on your device. All
analysis is performed locally in your browser. All data is stored in your
browser's built-in IndexedDB storage. Polaris makes zero network requests; no servers, no cloud, no analytics, no telemetry, no tracking. Nothing leaves
your browser, ever.

Polaris does not access X's API. It reads only publicly visible information on
the page; the same data anyone can see by visiting a profile.

You can delete all stored data at any time from the settings panel, or delete
individual profiles from the dashboard. Uninstalling the extension removes
everything.

FREE TO USE

All core features are available for free. No account required. No sign-up. Just
install and start analysing.
