Does the plugin slow down my site?
No. It sends one small ping per hour, and the visitor statistics use one small script that loads after the page.
Can I disconnect?
Yes. Disconnecting removes the application password of Werk AI. Deactivating the plugin stops the pings.
Is the plugin useful without Werk?
It exists to connect your site to Werk. If you do not use Werk yet, Connect to Werk creates your account.
