Install NibWP and switch it on

Installing NibWP is an ordinary WordPress plugin install. The part people miss is the last step: abilities stay off until you turn them on yourself.

Before you start, check the two minimums from the plugin header — WordPress 6.5 or newer, and PHP 8.0 or newer. You also need an administrator account, since every NibWP screen requires the manage_options capability.

1. Install it. Either search for the plugin in the WordPress.org plugin directory and install from there, or take the .zip and use Plugins → Add New → Upload Plugin. Uploading the nibwp folder into /wp-content/plugins/ by hand works too.
2. Activate it. On multisite, activate per site — each subsite gets its own endpoint.
3. Find the menu. A NIBWP item appears near the top of the wp-admin sidebar. It opens on Dashboard, with Connect, Integrations, AI Abilities, Memory, Audit Log, Sandbox, Status and Settings beneath it.
4. Switch on abilities. Go to NibWP → Connect. Step 1 is Enable AI Abilities: tick Turn on AI Abilities for this site and press Save Settings. A confirmation panel appears first, and it is blunter if the site looks like production — read it before pressing Yes, enable it.

Two things to know afterwards. The switch is tied to the address it was turned on for, so a site that moves to a new domain has its abilities disabled until you turn them on again. And individual abilities have their own toggles under NibWP → AI Abilities, so you can keep the master switch on and still narrow what is exposed.
