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`. See the [OpenAI Terms of Use](https://openai.com/policies/) and [Privacy Policy](https://openai.com/policies/privacy-policy/). * **OpenRouter** — endpoint `openrouter.ai`. See the [OpenRouter Terms](https://openrouter.ai/terms) and [Privacy Policy](https://openrouter.ai/privacy). * **Google Gemini (AI Studio)** — endpoint `generativelanguage.googleapis.com`. See the [Gemini API Terms](https://ai.google.dev/gemini-api/terms) and [Google Privacy Policy](https://policies.google.com/privacy). * **NVIDIA NIM** — endpoint `integrate.api.nvidia.com`. See the [NVIDIA Terms of Service](https://www.nvidia.com/en-us/about-nvidia/terms-of-service/) and [Privacy Policy](https://www.nvidia.com/en-us/about-nvidia/privacy-policy/). * **Anthropic (Claude)** — endpoint `api.anthropic.com`. See the [Anthropic Consumer Terms](https://www.anthropic.com/legal/consumer-terms) and [Privacy Policy](https://www.anthropic.com/legal/privacy). * **Custom API** — if you select 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. ## Screenshots [⌊Generate Fields page – describe the fields you need in plain English and click Generate.⌉⌊Generate Fields page – describe the fields you need in plain English and click Generate.⌉[ Generate Fields page – describe the fields you need in plain English and click Generate.

Three providers are completely free: – **OpenRouter** – Dozens of free models, no billing needed (sk-or-v1-… key) – **Google Gemini** – Free tier via Google AI Studio, no credit card required (15–500 req/day depending on model) – **NVIDIA NIM**– Free inference credits auto-added on signup (nvapi-… key) ### Which AI provider gives the best results? For free usage: **Gemini Flash Latest** (Google AI Studio) or **Gemini 2.0 Flash Experimental** (OpenRouter) give the best JSON output quality. For variety: **NVIDIA NIM** lets you try 100+ frontier models for free. For paid usage: **GPT-4o Mini**( best value) or **Claude 3.5 Sonnet** (most capable). ### Does this work with ACF Pro? Yes! The plugin is compatible with both free ACF and ACF Pro. When ACF Pro is active, field groups are created using the Pro import system. ### Can I generate repeater fields with sub-fields? Absolutely. Just mention “repeater” in your prompt. Example: “Create a testimonials repeater with name, company, photo, and quote fields.” ### Is my API key secure? Yes. API keys are stored in WordPress options with password field masking, never exposed in JavaScript, and transmitted only via server-side `wp_remote_post()` calls. ### What happens if the AI returns malformed JSON? The plugin’s JSON validator automatically strips markdown code fences, extracts JSON blocks from text responses, and provides helpful error messages guiding you to fix the issue. ### Can I use a custom/self-hosted AI? Yes! Use the **Custom API** provider with any OpenAI-compatible endpoint (Ollama, LM Studio, etc.). ### Which ACF field types are supported? text, textarea, number, image, file, repeater, select, checkbox, true_false, url, email, wysiwyg, relationship, gallery. ### How many free requests can I make per day? It depends on the provider: – **OpenRouter**: ~50 requests/day per free model ( many free models available) – **Google Gemini 2.0 Flash**: 1,500 requests/day, 15 requests/minute – **Google Gemini 2.5 Flash**: 500 requests/day, 10 requests/minute–** NVIDIA NIM**: ~40 requests/minute, free credits top up automatically ## Reviews There are no reviews for this plugin. ## Contributors & Developers “DB AI Field Generator for Advanced Custom Fields” is open source software.
