FAQ
-
Do I need an OpenAI API key?
-
Yes, the free version requires an OpenAI API key. You can get one at platform.openai.com. OpenAI offers a free tier with credits to get started.
-
How much does it cost to use?
-
The plugin itself is free. You only pay for OpenAI API usage, which is typically a few cents per article. GPT-4o-mini is very affordable (approximately $0.01 per 1000 articles).
-

Yes! The plugin works with any WordPress theme. It integrates directly into the WordPress editor.

-
Does it work with Gutenberg?
-
The free version works with the Classic Editor (TinyMCE). Gutenberg support is available in the Pro version.
-
Will it slow down my site?
-
No. Link generation happens in the admin area when you click the button. There’s no impact on your site’s front-end performance.
-
Can I undo the changes?
-
Yes! The editor’s undo function (Ctrl+Z / Cmd+Z) works normally after links are inserted.
-
How many links should I add per article?
-
We recommend 3-5 internal links per article for most content. Quality and relevance are more important than quantity.
-
Does it support other languages?
-
Yes! The AI can generate links for content in any language that OpenAI supports.

Your content is sent to OpenAI’s API for analysis using HTTPS. OpenAI does not use API data for training. API keys are stored securely in your WordPress database.
