Clipboard Inspector

See what sites can read from your clipboard — and how they can silently overwrite it without you noticing.

Reading

Read your clipboard

Clicking the button below triggers the real browser clipboard permission prompt — exactly as any website would. If you grant it, your current clipboard contents will be shown and analysed. Nothing is stored or sent anywhere.

Writing

Sites can also overwrite your clipboard

The clipboard write API needs no permission prompt in most browsers — a site can silently replace what you've copied the moment you interact with the page. A malicious site could swap a safe address for a scammer’s wallet address the instant you click “Copy”.
