Chrome extension / selection-only / local-only

Inspect selected text locally

Avoid pasting an entire page elsewhere. Count bytes and format JSON from only the selected text. Nothing is sent outside the device.

Three steps

  1. Open Chrome’s extensions page, unpack the downloaded ZIP, and load it.
  2. Select text on any page and choose “Local Selection Tools” from the context menu.
  3. Review byte count and formatted JSON in the extension page; copy only when you press copy.

The selected text travels through a one-time token to the extension page. The token is removed after receipt, and the text is not placed in a URL or sent to a server.
