External Services

This plugin relies on external AI API services to provide image analysis and text generation capabilities. Data is transmitted to the following third-party service:

OpenRouter

Service URL: https://openrouter.ai/

Data Sent: When using OpenRouter, image attachment URLs (or Base64-encoded image data for local or private environments), post titles, post content (context), the site URL (HTTP-Referer header), and the site title (X-Title header) are sent to the OpenRouter API (https://openrouter.ai/api/v1/chat/completions) when generating metadata or testing the connection. Additionally, the settings dashboard queries https://openrouter.ai/api/v1/models to retrieve available vision models.
