Dropndot AI Content for Custom Fields is a powerful WordPress plugin that brings AI-powered content generation directly to your custom fields. Generate high-quality content for any custom field with a single click, using your own OpenAI or Google Gemini API key, or the WordPress AI Client and whichever AI provider you have connected under Settings Connectors (OpenAI, Google Gemini, Anthropic, and others).

Key Features

Smart Field Detection: Automatically detects all custom fields (ACF, Meta Box, Pods, standard WordPress fields, Yoast SEO, Rank Math)
One-Click Generation: Generate content for any field with a single click
Intelligent Content Detection: Automatically detects appropriate content type based on field name
Custom Prompts with Limits: Set custom AI prompts for each field with explicit character/word limits
Precise Length Control: Dedicated character and word limit fields ensure AI respects your requirements
Complete Sentence Truncation: Smart truncation at sentence boundaries, never cuts off mid-word
Advanced Internal Linker: AI-powered keyword extraction and smart post matching for internal linking
AI Chat Assistant: Chat with AI about your article content for suggestions and improvements
Preview & Edit: Review AI-generated content before saving
Two Ways to Connect: Use your own encrypted OpenAI / Google Gemini API key, or the WordPress AI Client (Settings Connectors)
Model Selection: Choose the OpenAI and Gemini model; the OpenAI list is filtered to the models your key can reach
Usage Guardrails: Per-user rate limiting and site-wide daily request and token quotas
Response Cache: Identical generations are served from a short-lived cache (“Regenerate” always bypasses it)
Monitoring: Today’s usage and a log of the 100 most recent AI calls
Optimized Token Usage: Intelligent content truncation to prevent token limit errors
User Access Control: Granular user permissions
Format Support: Plain text, WYSIWYG, JSON, lists, and paragraphs

Safety Net: Intelligent post-processing ensures limits are never exceeded

Dynamic Limits: Adjusts content based on character/word requirements
Configurable Ceilings: Max output tokens, retry attempts and continuations are adjustable in settings

External services

This plugin sends content to an AI provider to generate text. No request is ever made until a site administrator configures a provider (an API key in the plugin settings, or a provider under Settings Connectors) and a permitted user actively triggers a feature. The plugin does not collect analytics and does not track visitors or site users.

When an API key is saved in the plugin settings, requests go directly from your server to the selected provider (OpenAI or Google Gemini). When no key is saved, requests go through the WordPress AI Client to the provider connected under Settings Connectors.

What is sent for content generation, internal links and chat: the post title and post content of the entry being edited (truncated before sending), the custom prompt configured for the field, the chat messages you type, the recent chat history of the current conversation, and your WordPress display name so the assistant can address you by name.

When it is sent: only when a logged-in, permitted user clicks a “Generate” or “Regenerate” button, requests internal links, or sends a chat message.

OpenAI API

Used when “OpenAI (GPT)” is selected and an API key is saved. Requests are sent to https://api.openai.com/v1/chat/completions with the data listed above and your API key. To show which models your key can use, the settings page also sends your API key to https://api.openai.com/v1/models when the key is saved, when “Refresh available models” is clicked, or when the settings page is opened after the cached list (kept for 6 hours) has expired.

Google Gemini API

Used when “Google Gemini” is selected and an API key is saved. Requests are sent to https://generativelanguage.googleapis.com/ with the data listed above and your API key.

WordPress AI Client / connected providers

Used when no API key is saved in the plugin and an AI provider is connected under Settings Connectors (WordPress 7.0+). The request is sent with the data listed above to whichever provider the site owner has connected. Official provider plugins register with the Connectors screen and send the request from your server. Provider terms depend on which connector you enable, for example:

OpenAI terms: https://openai.com/policies/terms-of-use/
OpenAI privacy: https://openai.com/policies/privacy-policy/
Google Gemini terms: https://ai.google.dev/gemini-api/terms
Google privacy: https://policies.google.com/privacy
Anthropic terms: https://www.anthropic.com/legal/terms
Anthropic privacy: https://www.anthropic.com/legal/privacy

Upstash Search (optional)

Used only for the internal linking feature, and only when “Use Upstash for Search” is enabled in the Internal Links settings and an Upstash REST URL and token are configured. When it is disabled, the plugin uses the built-in WordPress search instead and contacts no external search service.

What is sent: search queries derived from the keywords of the post being edited, sent to the Upstash Search REST endpoint you configure, together with your Upstash REST token.

When it is sent: only when a user generates internal link suggestions while the option is enabled.
