Frequently asked questions about Supercharger.
Does Supercharger generate new content for my site?
No. Supercharger enhances and enriches your existing content. It does not write new articles, create posts, or publish anything on your behalf. All AI-generated output — summaries, highlights, quotes — is derived from content you’ve already written.
Does Supercharger send my content to third parties?
Yes — to your configured AI provider. When Supercharger processes a post, the post content is sent to your AI provider’s API for analysis. This is necessary for the plugin to function. Your content is subject to the privacy policy and data handling terms of your chosen provider.
Supercharger itself does not send any data to its own servers or any third party other than the AI provider you configure.
Which AI provider should I use?
Any supported provider will work for text generation. If you want to use the AI Recommendations module, you must have an OpenAI API key specifically for embeddings. See AI Providers for an overview of each option.
Can I use Supercharger without an API key?
No. Supercharger requires at least one AI provider API key to function. The plugin does not include any built-in AI capabilities — it acts as a client to external AI services.
Modules
Can I use multiple modules at the same time?
Yes. All modules operate independently and can all be active simultaneously. There are no conflicts between modules.
Why is there no output on my post?
The most common reasons are: the module is not enabled, the post type is not included in the settings, or the post has not been processed yet. See Troubleshooting for a full diagnostic checklist.
Can I control which posts a module appears on?
Currently, modules apply to all posts of the configured post types. To exclude an individual post, use the Exclude from Supercharger toggle in the Gutenberg sidebar.
Indexing & Recommendations
How many posts do I need for recommendations to work?
Recommendations work best with at least 20–30 indexed posts. With fewer posts, the semantic similarity calculation has less to compare against and results may be limited.
How often is the index updated?
The index is updated automatically whenever a post is saved in WordPress. New posts are added to the indexing queue and processed on the next cron run. There is typically a delay of a few minutes to a few hours depending on your cron setup and queue depth.
Will indexing slow down my site?
No. Indexing runs entirely in the background via WordPress cron. It does not affect page load times or front-end performance.
Why are some posts showing “Failed” in the index status?
Failed posts usually indicate an API error during indexing. Common causes: invalid API key, rate limit exceeded, or post content that’s too short. Check the Logs for details and see Troubleshooting.
Pro & Licensing
Do I need both the free and Pro plugins?
Yes. The Pro plugin extends the free version — both must be installed and active. The Pro plugin adds the Pro modules and license management.
What happens if my Pro license expires?
Pro modules will stop functioning. Free modules continue to work normally. Your settings are preserved, and re-activating a valid license restores Pro functionality.
Technical
Is Supercharger compatible with page caching plugins?
Yes, with a caveat. AI-generated output is server-side rendered HTML. If a full-page caching plugin caches your pages, the Supercharger widgets will be cached along with the page content — which is generally fine, since the AI output doesn’t change on every request. However, after regenerating AI content for a post, you should clear your caching plugin’s cache for that post to see the updated output.
Does Supercharger work with multisite?
Supercharger supports WordPress multisite. Each site in the network has its own settings and index.
Is Supercharger compatible with the Classic Editor?
The Gutenberg sidebar features require the block editor. However, all front-end output (modules rendering on posts) works regardless of which editor you use. The Gutenberg sidebar is simply unavailable when using the Classic Editor; you can still manage settings from Supercharger → Modules.
