Your Rank Math Content AI tools stop working or run out of uses, even though your site has a paid Rank Math plan.
Why this happens. Content AI is a separate subscription from the Rank Math SEO plugin license. The PRO, Business, and Agency plugin plans include only small complimentary monthly Content AI limits, intended as a trial. Once those uses are exhausted, the tools stop responding until the month resets or a dedicated Content AI plan is added.
What you can do. To restore full access, add a Content AI plan to the Rank Math account your site is connected to, then allocate its usage to that site. This activates the full toolset, including AI Visibility. You do not need to reinstall or reconnect the plugin.
