External services

This plugin is an interface to third-party AI provider APIs. To turn the text prompt you type into an ACF field group, it sends a request to the AI provider you select on the Settings page.

What is sent, and when:

• A request is made only when you click “Generate” (or otherwise trigger an AI generation). The plugin does not contact any external service on normal page loads.
• Each request contains only the prompt text you typed and the model name you selected. No other site content, user information, or visitor data is transmitted.
• You must enter your own API key for the chosen provider. Nothing is sent until a key is saved and you trigger a generation. API keys are stored in your site’s database (WordPress options) and are sent only to the matching provider to authenticate your request.

Depending on the provider you configure in Settings, data is sent to one of the following services, each governed by its own terms of use and privacy policy:

• OpenAI – endpoint: api.openai.com – Terms: https://openai.com/policies/ – Privacy: https://openai.com/policies/privacy-policy/
• OpenRouter – endpoint: openrouter.ai – Terms: https://openrouter.ai/terms – Privacy: https://openrouter.ai/privacy
• Google Gemini (AI Studio) – endpoint: generativelanguage.googleapis.com – Terms: https://ai.google.dev/gemini-api/terms – Privacy: https://policies.google.com/privacy
• NVIDIA NIM – endpoint: integrate.api.nvidia.com – Terms: https://www.nvidia.com/en-us/about-nvidia/terms-of-service/ – Privacy: https://www.nvidia.com/en-us/about-nvidia/privacy-policy/
• Anthropic (Claude) – endpoint: api.anthropic.com – Terms: https://www.anthropic.com/legal/consumer-terms – Privacy: https://www.anthropic.com/legal/privacy
• Custom API – if you choose the “Custom API” provider, requests are sent to the OpenAI-compatible endpoint URL that you enter yourself. Review the terms and privacy policy of whichever service that endpoint belongs to.
