About this plugin
Swell AI Image Block uses artificial intelligence to analyze your post content and automatically find the most relevant royalty-free stock photo for each location in your article. Simply add the block and let AI do the rest. A built-in AI Featured Image finder also searches for a featured image based on your post title — no more hunting for the right photo before you hit publish.
Features:
- Automatic Image Selection – AI analyzes the content around the block and selects the best matching stock photo
- AI Featured Image Finder – Find and set a featured image based on your post title directly from the Document sidebar
- Multiple Sources – Searches Unsplash, Pexels, and Wikimedia Commons for free, high-quality images

- Manual Search – Override the AI selection with your own keyword search
- Proper Attribution – Automatically adds photographer credit as required by image licenses
- Premium Suggestions – Optional premium image recommendations from iStock

Third-Party Services
This plugin can connect to external services in two ways:
Option 1 — Managed Service (default, no setup required)
By default, this plugin routes requests through our secure API server for AI-powered content analysis and image matching. Content is processed in real-time and is not stored permanently.
- Service URL: https://smart-image-block-production.up.railway.app
- Privacy Policy: https://swellapps.ai/privacy-policy/
Option 2 — Your Own API Keys (Settings → Swell AI Image Block)
You may instead enter your own API keys. In this case, your WordPress site calls the APIs directly and no data passes through our server.
Our managed server and the direct-key mode both communicate with:
