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).
-
Will it work with my theme?
-
Yes! The plugin works with any WordPress theme. It integrates directly into the WordPress editor.
-
Can I customize the AI prompts?
-
Custom prompts are available in the Pro version. The free version uses optimized default prompts.
-
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.
-
Is my content secure?
-
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.
